Emerald Cockroach (Pseudoglomeris magnifica)
£10.00
Living up to their "magnifica" name, these Cuban jewels are arguably the most beautiful cockroach species in the hobby. Their stunning metallic green coloration shifts from emerald to lime depending on the light, creating an almost iridescent effect that photographs can barely capture. While more challenging than typical feeder species, their incredible appearance and unique behaviors make them worth the extra attention for dedicated keepers.
A Glimpse
Origin: Cuba and Caribbean Islands
Scientific Name: Panchlora magnifica (formerly P. nivea)
Difficulty Level: Medium
Adult Size: 25-30mm (1-1.2 inches)
Rarity: Uncommon
Temperature: 78°F to 88°F (26°C to 31°C)
Humidity: 75% to 85%
Favorite Foods: Fruits, flowers, soft woods
Supplements: Bee pollen, fruit beetle jelly, brown sugar water
Overview
The Emerald Cockroach belongs to the Panchlora genus, known for their vibrant green coloration - a rarity among cockroaches. Adults display a brilliant metallic green that's unlike anything else in the roach world, while nymphs start brown and gradually develop their emerald sheen through successive molts. They're strong fliers and excellent climbers, capable of scaling any surface including glass, which adds complexity to their husbandry.
Native to tropical Caribbean environments, they naturally inhabit tree canopies where they feed on fruits, flowers, and tree sap. This arboreal lifestyle means they prefer vertical space and appreciate setups that mimic forest canopies. They're also notably clean for roaches, producing minimal odor when properly maintained, though they do emit a distinctive sweet smell when disturbed - some describe it as similar to cucumber or fresh-cut grass.
Basic Care
Enclosure Setup:
Minimum 20-litre container for starter colonies (10-15 individuals)
SECURE, fine-mesh ventilation essential - adults fly readily
4-5 inch substrate layer for nymphs to burrow
Vertical cork rounds and branches crucial
Live or artificial plants enhance natural behavior
Petroleum jelly barrier recommended around lid edges
Substrate Mix:
35% coconut fiber
25% composted leaves
20% rotted white wood (important for nutrition)
15% sphagnum moss
5% sand for drainage
Environmental Conditions: These roaches demand consistently warm, humid conditions - they're truly tropical and won't tolerate temperature drops. Maintain temperatures above 75°F at all times; prolonged exposure below 70°F can be fatal. High humidity is essential but must be balanced with ventilation to prevent bacterial and fungal issues. Mist daily but ensure good airflow. They benefit from a consistent photoperiod and may become more active with appropriate day/night cycling.
Feeding: Feed every other day with emphasis on sweet, soft foods. Ripe fruits like banana, mango, and papaya are eagerly accepted. They have a particular fondness for apple sauce and fruit baby food. Brown sugar water (offered in bottle caps with cotton) is greatly appreciated. Soft, white-rotted wood should always be available as they consume it for both nutrition and digestive health. Fresh flowers, especially sweet varieties like honeysuckle, are a special treat. Remove uneaten foods within 24 hours in this high-humidity environment.
Breeding Notes
P. magnifica can be slow to establish compared to other species. Females produce oothecae containing 20-30 eggs, which they carry briefly before depositing in substrate. Incubation takes 45-60 days at optimal temperatures. Nymphs are initially quite small (3-4mm) and brown, requiring finely ground foods. The color change to green begins around the 4th instar. Full maturity takes 5-7 months. Adults live 12-18 months, with females typically outliving males.
Special Considerations
Their ability to fly and climb any surface makes escape prevention critical. Double-check lid security and consider petroleum jelly barriers. They're attracted to lights and may congregate near enclosure lighting. While beautiful, they're not handling-friendly - they're fast, flighty, and the oils from human skin can damage their delicate coloration.
This species seems particularly sensitive to pesticides and household chemicals. Never use treated wood products or collect leaves from areas that may have been sprayed. Their higher temperature requirements mean heating is essential year-round in most UK homes. Consider using heat mats or ceramic heat emitters with thermostats for stable temperatures.

Extinct/Cave roach (Simandoa Conserfariam)
£10.00
These remarkable roaches carry a unique distinction in the invertebrate hobby - they're extinct in the wild, existing only in captivity after their sole habitat was destroyed in Guinea. Originally discovered in the Simandou Mountains, these living fossils represent a successful conservation story through hobbyist breeding programs. Their manageable size, wingless nature, and fascinating social behaviors make them both a privilege and a responsibility to keep.
A Glimpse
Origin: Simandou Mountains, Guinea (Extinct in Wild)
Scientific Name: Simandoa conserfariam
Difficulty Level: Easy
Adult Size: 20-25mm (0.8-1 inch)
Rarity: Uncommon
Temperature: 75°F to 85°F (24°C to 29°C)
Humidity: 70% to 80%
Favorite Foods: Protein-rich foods, fruits, vegetables
Supplements: Fish flakes, dog food, bee pollen
Overview
Simandoa conserfariam has a tragic yet inspiring story. Their only known habitat - a single cave system in Guinea - was destroyed by bauxite mining operations. Fortunately, specimens had already entered the hobby trade, and dedicated keepers worldwide now maintain the entire global population. The species name "conserfariam" literally means "to preserve," reflecting their conservation-dependent status.
These medium-sized, wingless roaches display interesting yellow-brown coloration with distinctive striping on nymphs. They're completely unable to climb smooth surfaces or fly, making them excellent candidates for open-top displays. Unlike many roach species, they exhibit complex social behaviors including communal child-rearing and group feeding behaviors that make them endlessly fascinating to observe.
Basic Care
Enclosure Setup:
Minimum 10-litre container for starter colonies (10-15 individuals)
Moderate to low ventilation to maintain humidity
3-4 inch substrate layer for burrowing behavior
Multiple layers of egg cartons or cork bark
Dark hiding areas essential for security
Shallow water dish with sponge or crystals
Substrate Mix:
40% coconut fiber
30% decomposed hardwood
20% sphagnum moss
10% crushed leaves
Environmental Conditions: Cave roaches naturally inhabited a high-humidity environment with stable temperatures. Maintain consistent warmth between 75-85°F for optimal breeding. Humidity should remain high but not saturated - aim for that "cave-like" feeling without creating swamp conditions. Mist every other day, focusing on one side to create a moisture gradient. These roaches are largely nocturnal and prefer dim conditions, though they'll adapt to normal room lighting.
Feeding: Feed 2-3 times weekly with protein being particularly important for this species. They're enthusiastic eaters with a preference for protein-rich foods. Dry dog or cat food (fish-based formulas work well), fish flakes, and bee pollen should form the staple diet. Supplement with fresh fruits and vegetables - they particularly enjoy apple, carrot, and squash. Always provide food in shallow dishes to prevent substrate contamination. Remove uneaten fresh foods within 24-48 hours.
Breeding Notes
S. conserfariam are ovoviviparous, giving birth to live young rather than laying egg cases. Females gestate for approximately 60 days before producing 20-30 small nymphs. With proper nutrition and temperatures, colonies can grow steadily. Interestingly, this species shows communal care behaviors - adults will allow nymphs from other mothers to shelter beneath them. Sexual maturity is reached in 4-5 months. Maintaining genetic diversity is important given their extinction in the wild, so avoid excessive culling of breeding adults.
Special Considerations
As an extinct-in-wild species, keeping Simandoa comes with an ethical responsibility to maintain healthy colonies. Never release them outdoors, even if your climate seems suitable. Share offspring with other responsible keepers to ensure the species' continued survival. They cannot climb glass or plastic, but can climb rough surfaces like wood or fabric, so ensure ventilation holes are appropriately sized.
This species seems more sensitive to environmental toxins than many roaches - avoid using any pesticides or chemicals near their enclosure. Cedar and pine should never be used as substrates or hides due to toxic oils.

Madagascar Hissing Cockroach (Gromphadorhina sp)
£7.50
Madagascar Hissing Cockroaches are one of the world's largest cockroach species and among the most recognisable invertebrates kept as pets. They're famous for one thing: the loud hissing sound they produce by forcing air through specialised breathing holes. Unlike most insects that make noise by rubbing body parts together, hissers use a respiratory mechanism more similar to how vertebrates vocalise. They're docile, wingless, easy to care for, and surprisingly personable—making them a classic choice for anyone interested in keeping invertebrates.
Species Information
Scientific name: Gromphadorhina sp. (most commonly G. portentosa, though several similar species are often sold interchangeably)
Common names: Madagascar Hissing Cockroach, Hisser, MHC, Malagasy Hissing Cockroach
Origin: Madagascar
Adult size: 5–7.5cm (2–3 inches), occasionally up to 10cm
Lifespan: 2–5 years
Difficulty: Easy
Taxonomy Note
There are around 20 species of large hissing cockroaches from Madagascar, and pet dealers frequently confuse them with one another. Gromphadorhina portentosa is the most commonly kept species, but G. oblongonota and G. picea are also regularly sold—often under the same name. Care requirements are essentially identical across species, so this rarely matters for keepers.
Appearance
Hissing cockroaches have a distinctive look:
Body: Oval-shaped, shiny brown to dark mahogany, almost black in some individuals
Exoskeleton: Thick, hard, and waxy
Wings: Completely wingless (unlike most cockroaches)
Legs: Equipped with pads and hooks that allow them to climb virtually any surface, including smooth glass
Size: Among the largest cockroaches in the world—adults are substantial, impressive insects
Sexual Dimorphism
Males and females are easy to tell apart once mature:
Males: Have prominent "horns" (raised bumps) on the pronotum behind the head. Antennae are hairier. Generally more aggressive (toward other males, not handlers). Slightly smaller than females.
Females: Lack horns or have only very small bumps. Antennae are smoother. Tend to be larger and wider than males.
Underside: Males have three smaller segments at the rear of the abdomen; females have one larger segment.
The Hissing
The defining feature of these cockroaches is their ability to hiss. They produce sound by forcing air through modified breathing pores (spiracles) on their abdomen. This is unusual—most insects make noise through stridulation (rubbing body parts together) or vibrating membranes.
Types of hiss:
Disturbance hiss: A loud, snake-like sound used when startled or threatened. All cockroaches from the fourth moult onward can produce this.
Courtship hiss: Males use this to attract females.
Fighting hiss: Males hiss during territorial disputes. Winners hiss more than losers—hissing helps establish hierarchy.
The hiss is genuinely loud and can startle people who aren't expecting it. It's part of what makes these cockroaches interesting to keep.
Behaviour
Nocturnal: Most active at night, spending daytime hours hiding
Docile: Generally calm and tolerant of handling—one of the more "handleable" invertebrates
Non-aggressive: Cannot bite humans (mouthparts aren't strong enough) and pose no threat
Climbing: Excellent climbers capable of scaling smooth glass—secure enclosures essential
Social: Live communally in the wild and do well in groups in captivity
Male aggression: Males will fight other males for territory and females, ramming each other with their horns and pushing with their abdomens. This looks dramatic but doesn't cause injury.
Territorial: Males may claim and defend small territories (a rock, a piece of bark) for extended periods
Despite being cockroaches, hissers are clean animals that groom themselves frequently. They don't have the pest associations of household cockroach species.
Enclosure Setup
Container
Glass or plastic aquarium, plastic storage container, or purpose-built terrarium
Size depends on colony size—a 5–10 gallon tank suits a small group; larger colonies need proportionally more space
Secure, well-ventilated lid is essential
Escape prevention: They can climb smooth surfaces. Apply a 5cm band of petroleum jelly around the top inside edge of the enclosure to prevent escapes. This is important.
Substrate
Several options work:
Coconut fibre (coco coir)
Peat moss
Sphagnum moss
Wood chips (not cedar or pine)
Some keepers use no substrate at all for easier cleaning
If using substrate, keep it slightly moist but not wet.
Hides and Climbing
Egg cartons: The classic choice—cheap, provides lots of surface area and hiding spots, easy to replace
Cork bark
Cardboard tubes
Vertically placed bark or branches for climbing
Hissers like dark hiding places and will spend most of the day tucked away. Providing adequate hides keeps them comfortable and reduces stress.
Temperature
Survival range: Mid-teens°C (60s°F) to around 35°C (95°F)
Optimal range: 24–29°C (75–85°F)
Breeding: Warmer temperatures (27–32°C / 80–90°F) encourage faster breeding
Room temperature: They'll survive at typical UK room temperatures but will be less active and breed slowly
If supplemental heating is needed, heat mats on the side of the enclosure or ceramic heat emitters work well. Provide a temperature gradient so roaches can move to their preferred temperature zone.
Humidity
Range: 50–70%
Maintenance: Occasional misting, keeping substrate slightly damp, or providing a water source
Moulting: Adequate humidity helps ensure successful moults
They're reasonably tolerant of humidity variation and don't require precise conditions.
Water
Provide water via:
Water crystals/gel (safest option—prevents drowning)
Cotton wool or sponge soaked in water
Shallow dish with pebbles (to prevent drowning)
Misting (they'll drink droplets)
Fresh vegetables and fruit also provide moisture.
Diet
Hissing cockroaches are detritivores and omnivores—they're not fussy eaters:
Staples:
Dry dog or cat food (high protein)
Fish flakes
Chicken laying mash
Commercial roach chow
Fresh foods:
Vegetables: carrots, courgette, sweet potato, leafy greens, Chinese cabbage
Fruit: banana, apple, orange, melon (they love overripe fruit)
Notes:
They're not enthusiastic about lettuce or spinach
Remove uneaten fresh food before it moulds (within a few hours for fruit)
Dry food can be left available constantly
Feeding carrots and other carotenoid-rich foods can enhance their colour
Breeding
Hissing cockroaches breed readily in captivity:
Reproduction: Ovoviviparous—females carry eggs internally and give birth to live nymphs
Gestation: Approximately 60 days
Litter size: 15–60 nymphs per brood (typically 30–40)
Broods per year: 2–3 under good conditions
Sexual maturity: 3–6 months depending on temperature
Development: Nymphs undergo 6 moults over approximately 7 months to reach adulthood
Breeding behaviour:
Males court females with hissing and antennal contact
Mating occurs end-to-end and lasts around 30 minutes
Females are not receptive immediately after moulting—receptivity begins about 20 days later once their exoskeleton hardens
Breeding rate is moderate compared to some feeder species—don't expect explosive population growth. Warmer temperatures (27–32°C) speed things up considerably.
Handling
Hissing cockroaches are one of the better invertebrates for handling:
Generally calm and slow-moving
Tolerate regular handling well and can become quite "tame"
Cannot bite—mouthparts aren't capable of harming humans
May hiss when first picked up (this is normal and harmless)
Legs are spiny and can feel prickly but aren't harmful
Note: Some people develop allergies to hissing cockroaches with prolonged exposure and frequent handling. If you notice skin irritation or respiratory symptoms, reduce contact.
Feeder Use
Hissers can be used as feeder insects for larger reptiles, amphibians, and invertebrates, though they have limitations:
Pros: Good size for large animals, easy to gutload, relatively soft-bodied for their size
Cons: Breed more slowly than dedicated feeder species like dubia. Adult males have horns and spiny legs that can make them uncomfortable or potentially harmful for some predators to eat. Hard adult exoskeletons can be difficult for some animals.
Best practice: Use nymphs or adult females as feeders. Consider offering freshly killed adults to prevent struggling and potential injury from legs.
For serious feeder production, faster-breeding species like dubia or orange-head roaches are more practical. Hissers work better as pets or as occasional feeders for larger animals.
Mites
Hissing cockroaches commonly host a species of mite (Androlaelaps schaeferi) that lives on their bodies, particularly at the base of the legs. These mites have a commensal relationship—they eat debris and help keep the cockroach clean. They're not harmful to the roaches and don't affect humans. If you see small mites on your hissers, this is normal and not a cause for concern.
Care Summary
Temperature: 24–29°C optimal (room temperature acceptable, warmer for breeding)
Humidity: 50–70%
Substrate: Coco coir, peat moss, or bare floor
Hides: Egg cartons, cork bark, cardboard tubes
Diet: Dry dog food, fish flakes, vegetables, fruit
Water: Gel crystals, soaked sponge, or shallow dish with pebbles
Escape prevention: Petroleum jelly barrier around top of enclosure
Lifespan: 2–5 years
Breeding: Live-bearing, 30–60 nymphs per brood, moderate reproduction rate
Who Are They For?
Madagascar Hissing Cockroaches suit:
Beginners: Hardy, forgiving, and easy to care for
Educational settings: Popular in classrooms and zoos for teaching about insects
Handlers: One of the most handleable invertebrate species
Anyone wanting an unusual pet: They're genuinely interesting animals with observable behaviours
Keepers who want audible insects: The hissing is unique and entertaining
They're not ideal for:
High-volume feeder production (too slow-breeding)
Anyone who can't secure enclosures properly (they will escape if given the opportunity)
Madagascar Hissing Cockroaches have been popular pets for decades for good reason. They're large, impressive, surprisingly docile, and genuinely interesting to observe. The hissing alone makes them memorable—it's loud, distinctive, and never fails to get a reaction. If you're looking for an easy, low-maintenance invertebrate with genuine character, hissers are hard to beat.

Four Spotted Jade Roach (Eustegasta Buprestoides)
£10.00
One of the most visually striking roaches available in the UK hobby, the Four Spotted Jade Roach brings a burst of metallic beauty to any invertebrate collection. With their distinctive jade-green base coloration punctuated by four prominent golden-yellow spots, these Australian natives look more like living jewelry than traditional roaches. Their manageable size, inability to climb smooth surfaces, and relatively calm demeanor make them an excellent choice for keepers seeking something truly unique without the challenges of more demanding species.
A Glimpse
Origin: Eastern Australia (Queensland and New South Wales)
Scientific Name: Eustegasta buprestoides
Difficulty Level: Low to Moderate
Adult Size: 20-25mm (0.8-1 inch)
Rarity: Common
Temperature: 72°F to 82°F (22°C to 28°C)
Humidity: 60% to 70%
Favorite Foods: Leaf litter, fruits, vegetables
Supplements: Fish flakes, bee pollen, dried mushrooms
Overview
The Four Spotted Jade Roach inhabits forest floors in eastern Australia, where they play a crucial role in breaking down leaf litter and fallen fruits. Their common name perfectly describes their appearance - a lustrous jade-green body decorated with four distinct yellow-gold spots arranged symmetrically on their wing covers. The metallic sheen of their exoskeleton is particularly pronounced under good lighting, creating an almost iridescent effect that shifts between emerald and bronze tones.
Unlike many exotic roach species, E. buprestoides cannot climb smooth surfaces and are flightless, making them ideal for open-top displays or bioactive vivarium inhabitants. They're primarily nocturnal but will venture out during the day in established colonies, especially when favorite foods are offered. Adults exhibit mild sexual dimorphism, with males being slightly smaller and more slender than females.
Basic Care
Enclosure Setup:
Minimum 10-litre container for starter colonies (10-15 individuals)
Moderate ventilation - cross ventilation preferred
3-4 inch substrate layer essential for burrowing
Multiple hides using cork bark, egg cartons, or leaves
Dried oak or magnolia leaves as both food and shelter
Optional moss patches for humidity zones
Substrate Mix:
40% coconut fiber
30% decomposed hardwood leaf litter
20% rotted white wood
10% sand or perlite for drainage
Environmental Conditions: These roaches tolerate a wider temperature range than many tropical species, making them well-suited to UK room temperatures. They thrive between 22-28°C but can tolerate drops to 18°C without issues. Humidity should be moderate - they don't require the high humidity of rainforest species. Mist one side of the enclosure twice weekly, creating a moisture gradient. Good ventilation is important to prevent stagnant conditions.
Feeding: Feed 2-3 times weekly with a varied diet. They're excellent decomposers with a strong preference for dead leaves, which should always be available. Supplement with fresh vegetables like carrot, sweet potato, and squash. Fruits are eagerly accepted but should be given sparingly. Protein sources like fish flakes or dried mealworms should be offered weekly. They have a particular fondness for dried mushrooms and lichen when available.
Breeding Notes
E. buprestoides are ovoviviparous, producing live young after a gestation period of approximately 40-50 days. Females typically produce 15-25 nymphs per brood. Newborn nymphs are tiny (3-4mm) and immediately burrow into substrate, emerging to feed at night. They reach adult size in 4-6 months under optimal conditions. Adults live 12-18 months, with females capable of producing multiple broods. Colony growth is steady and manageable - they won't explode in numbers like some feeder species.
Special Considerations
Their inability to climb smooth surfaces makes them excellent for naturalistic setups, but they can climb rough surfaces like cork bark and wood. They're surprisingly good at squeezing through small gaps, so ensure ventilation holes are appropriately sized (maximum 2mm). While generally hardy, they're sensitive to excessive moisture - soggy conditions can lead to fungal issues. They coexist well with isopods and springtails in bioactive setups, occupying slightly drier areas than most isopod species prefer.
This species benefits from seasonal temperature variations, with slightly cooler winter periods (18-20°C) potentially improving breeding success. They're completely harmless and cannot infest homes, requiring specific conditions to survive and breed.

Sapphire Flower Cockroach (Eucorydia Yasumatsui)
£10.00
These jewel-like cockroaches from the Yaeyama Islands of Japan are among the most visually striking invertebrates available in the hobby. With their metallic blue-green sheen and bright orange head markings, Eucorydia yasumatsui brings a splash of tropical color that rivals any butterfly. While not as straightforward as some feeder roaches, their manageable size and stunning appearance make them an excellent choice for display colonies and those looking to branch out from isopods.
A Glimpse
Origin: Yaeyama Islands, Okinawa Prefecture, Japan
Scientific Name: Eucorydia yasumatsui
Difficulty Level: Moderate
Adult Size: 12-15mm (0.5-0.6 inches)
Rarity: Uncommon
Temperature: 72°F to 82°F (22°C to 28°C)
Humidity: 60% to 75%
Favorite Foods: Fruits, pollen, jellies, leaf litter
Supplements: Bee pollen, fruit beetle jelly, honey
Overview
The Sapphire Flower Cockroach is a diurnal species, meaning they're actually active during the day - unusual for roaches and perfect for display setups. Native to subtropical Japanese islands, they've evolved alongside flowering plants and can often be found visiting blooms in their natural habitat. Their common name comes from both their jewel-like coloration and their flower-visiting behavior. Adults display sexual dimorphism, with males showing more vibrant blue-green coloration and longer wings than females.
Unlike many cockroach species, these remain relatively small and are completely harmless, unable to bite or cause any household infestations. They're also notably clean in their habits, lacking the distinctive odor associated with larger roach species. However, they can be somewhat delicate compared to the hardier species like Dubia or Red Runners, requiring more consistent conditions.
Basic Care
Enclosure Setup:
Minimum 5-litre container for starter colonies (10-15 individuals)
Moderate ventilation - balance between humidity retention and air flow
2-3 inch substrate layer of coconut fiber mixed with leaf litter
Plenty of cork bark arranged both horizontally and vertically
Live or artificial plants enhance display value
Small branches for perching and molting
Substrate Mix:
40% coconut fiber
30% decomposed oak leaf litter
20% orchid bark or wood chips
10% sphagnum moss
Environmental Conditions: These roaches appreciate stable, warm conditions with moderate to high humidity. Unlike many tropical roaches, they don't thrive in extremely humid conditions and need some air circulation to prevent fungal issues. Mist every 2-3 days, allowing the enclosure to dry slightly between mistings. They benefit from a day/night light cycle and may display more during daylight hours with appropriate lighting.
Feeding: Feed 2-3 times weekly with variety being key to success. Fresh fruits like apple, pear, and melon are readily accepted. Artificial beetle jellies (the type used for stag beetles) are particularly appreciated and provide balanced nutrition. Bee pollen should be available constantly as a protein source. They'll also consume dried leaves and dead flowers, particularly from fruit trees. Remove uneaten fresh foods within 48 hours to prevent mold.
Breeding Notes
E. yasumatsui reaches maturity in 3-4 months under optimal conditions. Females produce small oothecae (egg cases) containing 8-12 eggs, which they partially bury in substrate or attach to bark. Incubation takes 4-6 weeks at proper temperatures. Nymphs are tiny (2-3mm) and require fine foods like powdered pollen and finely ground fish flakes. Colony growth is steady but not explosive - expect gradual, sustainable population increases rather than rapid booms.
Special Considerations
Adults are capable of flight, though they rarely do so in captivity. Ensure your enclosure has a secure lid with appropriate ventilation. They're more sensitive to pesticides and chemicals than many roach species, so avoid using treated wood or leaves from areas that may have been sprayed. Their small size and daytime activity make them excellent inhabitants for planted terrariums, where they serve as both decomposers and visual interest.
Temperature drops below 65°F can be fatal, particularly for nymphs. If keeping in cooler climates, supplemental heating may be necessary year-round.

Giant Flower Cockroach (Eucorydia Dasytoides)
£9.00
Giant Flower Cockroach (Eucorydia dasytoides) is a stunning species and the largest of the flower roaches currently available in culture. Native to Taiwan and parts of China, this species belongs to the Eucorydia genus - commonly known as flower roaches because males are frequently observed visiting flowers during the day in the wild.
What makes this species so desirable is the transformation. The nymphs are nothing to write home about - small, brownish, and frankly a bit dull. But after the final moult, adults emerge with a gorgeous metallic blue-green iridescent colouration that genuinely has to be seen to be believed. It's like keeping ugly ducklings that turn into tiny jewelled beetles.
Eucorydia dasytoides is considered one of the rarer species in the UK hobby. They're relatively new to culture here and remain highly sought after by collectors. Once you understand their needs, they're not particularly demanding to keep, though patience is required - nymphs take 7-10 months to reach adulthood.
A Glimpse
Origin: Taiwan, China (Southeast Asia)
Scientific Name: Eucorydia dasytoides
Difficulty Level: Easy to Moderate
Size: 15-20mm (adults)
Temperature: 20-27°C (can benefit from winter cooling)
Humidity: 50-70% (prefers drier conditions with good ventilation)
Favourite Foods: Fresh fruits, pollen, decaying leaves, protein supplements
An Overview
Eucorydia dasytoides is the largest species in the flower roach genus, reaching around 15-20mm as adults - roughly twice the size of the popular Sapphire Flower Roach (Eucorydia westwoodi). The UK stock currently in culture originates from Taoyuan, Taiwan.
In the wild, male flower roaches are pollinators, frequently visiting flowers during daylight hours. Females are more secretive, preferring to hide under bark and within rotting wood. This natural behaviour hints at their care requirements - they appreciate a setup that allows both burrowing and some climbing opportunity.
The entire Eucorydia genus is found exclusively in Asia, with various species occurring across China, Taiwan, Vietnam, Japan, India, and Southeast Asia. They belong to the Corydiidae family (previously known as Polyphagidae), which also includes the sand cockroaches.
One thing worth noting: adults are relatively short-lived compared to the lengthy nymph stage. Adult males typically live 2-3 months, with females lasting slightly longer. This makes starting with a reasonable group size important to ensure you have overlapping generations once the colony establishes.
Basic Care
Nymphs cannot climb smooth surfaces, but adults of both sexes can - secure lids are essential, especially since males can fly.
Ventilation is critical. This cannot be overstated. Poor airflow leads to fungal infections that can wipe out adults. Keep airflow high and humidity on the lower side.
These roaches do better in drier, well-ventilated enclosures rather than humid ones. Think more "airy" than "tropical rainforest."
Nymphs and females spend much of their time burrowed in substrate. Males are more active and visible.
A winter cooling period (diapause) at around 15-18°C for a few months can help synchronise male and female maturation times and improve breeding success. This isn't strictly essential but is beneficial.
Expect nymphs to take 7-10 months to reach adulthood. The wait is worth it.
Keep colonies small initially. A starter group of 5-10 nymphs in a compact enclosure makes monitoring easier and helps you track oothecae (egg cases).
Feeding
Flower roaches have a varied diet, and their wild pollen-feeding behaviour means they appreciate fresh fruits more than many other roach species.
Good food options include:
Fresh fruits (especially important for adults) - apple, banana, melon, berries
Vegetables - cucumber, courgette, carrot, leafy greens
Decaying hardwood leaf litter (oak, beech) - important dietary component
Fish flakes or similar protein supplement - once weekly
Pollen granules (if you can source them) - excellent for adults
Dog/cat biscuits (small amounts for protein)
Remove uneaten fresh food within 24-48 hours to prevent mould growth - this species is particularly susceptible to issues from mould.
Leaf litter isn't just decoration for flower roaches - it forms a significant part of their diet. A thick layer of decaying hardwood leaves on top of the substrate is essential.
Appearance and Behaviour
The transformation from nymph to adult in this species is genuinely remarkable. Nymphs are small, brownish, and rather unremarkable - they've been nicknamed the "ugly ducklings" of the roach world. They spend most of their time burrowed in substrate, only emerging occasionally.
Adults are a different story entirely. After the final moult, they develop stunning metallic blue-green iridescence that makes them one of the most visually striking roach species available. The colouration can vary somewhat between individuals.
Size-wise, Eucorydia dasytoides is the giant of the flower roach group at 15-20mm - still a relatively small roach overall, but nearly twice the size of the common Sapphire Flower Roach.
Males are more active and will explore the enclosure, while females remain more secretive and prefer hiding under bark or burrowing. Males can fly when disturbed, so be prepared for this when opening the enclosure.
Breeding behaviour is straightforward - males chase females briefly before initiating tail-to-tail copulation that lasts several hours. Females produce small oothecae (egg cases) once or twice weekly, each containing 5-10 eggs. Oothecae take approximately two months to hatch.
Habitat
For small starter colonies (up to 10 nymphs), a compact enclosure around 8x8x8cm works well and makes monitoring easier.
For established colonies, a larger enclosure such as a small kritter keeper or similar (around 15x10x12cm) is suitable.
Adults can climb and males can fly - ensure lids are secure with no gaps.
Excellent ventilation is essential. Multiple ventilation holes or mesh sections are recommended. This species does poorly in stuffy, humid conditions.
Temperature should be kept between 20-27°C for normal activity. A winter cooling period at 15-18°C for a few months helps synchronise breeding.
Humidity should be moderate - around 50-70%. Keep the enclosure on the drier side with occasional light misting to one corner. Do not keep this species wet.
No additional hides are strictly necessary as they'll burrow, but a piece of cork bark is appreciated and makes it easier to check on them.
Substrate Mix
Substrate requirements for flower roaches are straightforward but important.
A suitable substrate consists of:
Coconut fibre (coco coir)
Organic potting soil
Peat moss
Or a combination of the above
Substrate depth should be around 2.5-5cm (1-2 inches) to allow for burrowing.
On top of the substrate, add a thick layer (2.5-5cm) of decaying hardwood leaf litter. This is important - leaf litter serves as both food and habitat enrichment. Oak and beech leaves work well.
A small piece of cork bark provides a focal point and makes it easier to check on the colony without disturbing the substrate too much.
Designate one corner as a "hydration corner" - lightly mist this area when needed rather than wetting the entire enclosure. The substrate should be mostly dry with this one area kept slightly damp.
Replace substrate every 6-8 months to prevent frass buildup affecting the enclosure conditions.

Glowspot Cockroaches (Lucihormetica Subcincta)
£2.00
Glowspot Cockroaches (Lucihormetica subcincta) are one of the more sought-after roach species in the hobby, and for good reason. Males sport two striking yellow-orange spots on their pronotum that, in the wild, actually glow thanks to bioluminescent bacteria. In captivity they don't glow—whatever microorganisms cause that effect aren't present in captive-bred colonies—but they're still visually impressive roaches with a lot going for them.
Native to the montane forests of Colombia, these are calm, slow-moving burrowers that spend most of their time underground. They're closely related to the Headlight Cockroach (L. verrucosa) but can be distinguished by their smoother pronotum and pale ivory-coloured wings. They're often considered the "original" glowspot in the hobby, though they're actually a bit more challenging to breed than their warty cousin.
Fair warning: if you're after fast colony growth, these aren't the species for you. They're notoriously slow breeders—we're talking potentially 12+ months before you see any nymphs. But for keepers who appreciate beautiful, handleable roaches and don't mind playing the long game, Glowspot Cockroaches are genuinely rewarding to keep.
A Glimpse
Origin: Colombia, South America
Scientific Name: Lucihormetica subcincta
Difficulty Level: Easy to Moderate
Size: 24-28mm (adults)
Temperature: 22-29°C
Humidity: 50-70%
Rarity: Moderate
Favourite Foods: Leaf litter, decaying wood, vegetables, fruits
Supplements: Protein (fish flakes, dog/cat kibble), calcium sources
Overview
Lucihormetica subcincta belongs to the family Blaberidae and has been a hobby favourite for years. They originate from humid montane forests in central and northeastern Colombia, typically at elevations of 1,200-1,800 metres where they live under loose bark and within leaf litter.
The species is admired primarily for its colouration. Nymphs are dark maroon to glossy black with distinctive little orange heads—quite attractive in their own right. Adults are mostly black with a subtle bronzy sheen, and males have those famous two prominent yellow spots on their pronotum. The spots can even be manipulated through diet—feed them foods high in beta-carotene (like carrots) and the spots will deepen to orange.
One unique feature of L. subcincta compared to the similar Headlight Cockroach (L. verrucosa) is their ivory-coloured wings. While neither species can fly, the pale wings on subcincta give them a slightly different look. They also have a smoother pronotum—verrucosa has the "warty" bumps that give it its common name.
These roaches exhibit some interesting behaviour. Unlike many species that just hide under bark, Glowspots form semi-permanent burrows where they raise their young. Some hobbyists have observed adults actually dragging leaves into their burrows—a level of housekeeping you don't often see in cockroaches.
Appearance and Behaviour
Adults reach approximately 24-28mm in length. Females are slightly larger and broader than males, but the easiest way to tell them apart is the glowspots—only males have them.
Physical features:
Adults: Glossy dark brown to black with bronzy sheen
Males: Two prominent yellow-orange spots on pronotum
Females: Plain pronotum, no spots, broader body
Nymphs: Dark maroon/black with orange heads
Wings: Ivory/pale coloured (adults only, non-functional)
Behavioural traits:
Nocturnal—most active at night
Strong burrowing instinct—they'll spend significant time underground
Calm and slow-moving—one of the best handling species
Don't exhibit the frantic "evasive manoeuvres" common to many roach species
Adults can climb smooth surfaces; nymphs cannot
Cannot fly despite having wings
May display parental care behaviours
Their calm temperament makes them one of the better cockroach species for handling. They don't bolt when picked up, and they don't have the nervous energy that makes many roaches difficult to work with. For keepers who actually want to interact with their insects, these are an excellent choice.
Basic Care
Glowspot Cockroaches are hardy once established, but they have some specific requirements that set them apart from truly beginner-level species.
Temperature: Keep them between 22-29°C. They'll tolerate room temperature, but breeding activity increases noticeably when kept at the warmer end of their range (26-29°C / above 80°F). If breeding is your goal, invest in a heat mat for one side of the enclosure.
Humidity: Moderate humidity around 50-70% works well. The key is creating a moisture gradient—one side of the enclosure should be kept damp while the other stays drier. This lets them regulate their own moisture needs. Mist the damp side regularly but never let the substrate become waterlogged.
Ventilation: Good airflow is important. Use ventilated containers or add air holes to plastic tubs. Our screw-in air vents work well for this. Stagnant, overly humid conditions can cause moulting problems.
Substrate depth: This is critical—provide at least 8-10cm (3-4 inches) of substrate. These are dedicated burrowers that will dig down and create semi-permanent tunnels. Shallow substrate will stress them and discourage breeding.
Climbing: Adults can climb glass and smooth plastic, so you'll need a secure, escape-proof lid. Nymphs can't climb smooth surfaces, so escapes are mainly an adult concern. A thin layer of petroleum jelly around the top rim provides extra security if needed.
Feeding
Glowspot Cockroaches are omnivorous detritivores. They're not particularly fussy, though some keepers report them being pickier than their verrucosa relatives—occasionally ignoring fresh fruit that other roaches would devour.
Primary foods (always available):
Dead oak leaves and mixed hardwood leaf litter
Decaying/rotting wood—they'll consume this and it encourages breeding
These should form the foundation of their diet
Supplementary foods:
Vegetables: carrot, courgette, sweet potato, pumpkin
Fruits: banana, orange, apple (some colonies may ignore these)
Protein: fish flakes, soaked dog/cat kibble, dried shrimp
Insect jelly (clean, doesn't spoil, reportedly well-received)
Calcium: Provide cuttlebone or crushed eggshells for healthy moulting.
Feeding tip: If you want to intensify the colour of the males' spots, feed them foods high in beta-carotene like carrots. The thin cuticle over the spots allows the inner tissues to show through, and those tissues are affected by diet. More carotenoids = more orange spots.
Habitat
A plastic container with secure lid and ventilation works well for breeding colonies. Glass terrariums are fine for display but require more attention to humidity management.
Key requirements:
Deep substrate (minimum 8-10cm) for burrowing
Cork bark or tree bark pieces for surface hides
Generous leaf litter layer
Pieces of rotting wood (food source and breeding encouragement)
Moisture gradient—damp area with moss, drier area elsewhere
Good ventilation
Secure, escape-proof lid
Colony density tip: They actually seem to breed better when kept slightly crowded in smaller containers. This keeps them in close proximity with food, water, and each other. Small colonies spread across large enclosures may struggle to establish.
Substrate Mix
A moisture-retentive substrate that mimics their forest floor habitat works best.
Recommended mix:
Peat moss or coconut coir as a base
Well-rotted compost or organic topsoil (pesticide-free)
Small amount of sand for drainage
Pieces of decaying wood mixed in
Generous layer of dead oak leaves on top
The substrate should be just barely moist—damp but definitely not soggy. Create a moisture gradient by misting one end more heavily. Natural bark pieces stacked to provide shelter work better than egg cartons for this species and help maintain proper humidity in their burrow areas.
Breeding
Let's be honest: Glowspot Cockroaches are slow breeders. Very slow. This is probably their main drawback and something you should know going in.
What to expect:
Nymphs take 6-10 months to mature through 6-7 moults
Colonies may take 12+ months before producing offspring
Some keepers report waiting 17 months from acquiring nymphs to seeing the first babies
Females give birth to approximately 15 live nymphs per brood
Newborn nymphs are tiny (2-3mm) and will immediately burrow
They're ovoviviparous, meaning females retain eggs internally and give birth to live young. This is common in the Lucihormetica genus.
Breeding tips:
Keep temperatures at the higher end (26-29°C) to encourage breeding
Maintain the moisture gradient—humidity affects moulting success
Add rotting wood—it supplements diet and reportedly encourages breeding
Don't disturb them excessively—patience is key
Keep colonies slightly crowded rather than spread thin
Provide adequate protein for reproducing females
Be patient. These aren't prolific breeders like Dubia or Discoid roaches. If you want rapid colony growth, choose a different species. If you're happy to wait, the eventual reward of seeing those little orange-headed nymphs is worth it.
Comparing to Headlight Cockroaches (L. verrucosa)
Since we stock both species, here's how they compare:
Feature
Glowspot (L. subcincta)
Headlight (L. verrucosa)
Wing colour
Ivory/pale
Brown
Pronotum texture
Smooth
Warty/bumpy
Breeding
Slower, more challenging
Easier, more reliable
Nymph appearance
Maroon/black with orange heads
Shiny black with orange markings
Care difficulty
Moderate
Easy
Both species have the characteristic glowspots on males, and both don't actually glow in captivity. Care requirements are similar. If you're new to Lucihormetica, the Headlight Cockroach is the slightly easier starting point. If you've had success with verrucosa and want a new challenge, subcincta is a logical next step.
Who Are These Roaches For?
Glowspot Cockroaches suit:
Keepers who appreciate beautiful, handleable roaches
Patient hobbyists not expecting fast colony growth
Anyone wanting a calm display species
Experienced keepers looking beyond common feeder roaches
Those interested in the Lucihormetica genus
They're not ideal if:
You want rapid breeding for feeders
You expect them to glow (they won't in captivity)
You're impatient with slow-developing species
You want highly visible roaches (they burrow most of the time)
Glowspot Cockroaches have earned their status as one of the hobby's most sought-after species. They're not the easiest or fastest-breeding roaches, but they're hardy, beautiful, and have genuinely interesting behaviour. The males' yellow spots are striking even without the bioluminescence, and their calm temperament makes them a pleasure to work with. Just be prepared to wait—these roaches do things on their own schedule.

Indian Spotted Cockroaches (Therea Petiveriana)
£2.00
Indian Spotted Cockroaches (Therea petiveriana), more commonly known as Domino Cockroaches, are one of the few roach species that genuinely changes people's minds about cockroaches. With their striking black bodies covered in crisp white spots—looking exactly like domino tiles—they're about as far from the common house roach as you can get. Native to southern India, these are beautiful, easy-to-keep roaches that make excellent display animals and great beginner species.
What makes them particularly interesting is that their bold pattern isn't just for show. They've evolved to mimic the aggressive ground beetle Anthia sexguttata, which can spray chemical irritants at predators. By copying this beetle's appearance, Domino Cockroaches benefit from predators' learned avoidance—a clever bit of evolutionary trickery called Batesian mimicry.
Fair warning if you're buying nymphs: they don't look like much at first. Juveniles are plain brown and spend most of their time burrowed in the substrate. The dramatic black-and-white transformation only happens when they reach adulthood. But once they do, you'll understand why these are one of the hobby's most popular display roaches.
A Glimpse
Origin: Southern India & Sri Lanka
Scientific Name: Therea petiveriana
Common Names: Domino Cockroach, Seven-spotted Cockroach, Desert Cockroach
Difficulty Level: Easy
Size: Males ~25mm, Females ~35mm
Temperature: 21-29°C (70-85°F)
Humidity: 40-60% (air), moist substrate
Rarity: Common
Favourite Foods: Leaf litter, vegetables, fruits, protein supplements
Overview
Therea petiveriana belongs to the family Corydiidae and is considered one of the more "basal" or primitive cockroach groups. They're found in scrub forest habitats in southern India, where they spend the heat of the day burrowed under leaf litter or loose soil, emerging at dawn and dusk (crepuscular activity) to forage.
The species has been popular in the hobby for decades, though there's an interesting taxonomic note: in 2009, researchers suggested that most captive stock might actually be a separate species, Therea bernhardti, rather than true T. petiveriana. The two are visually similar and require identical care, so for practical purposes it doesn't change how you keep them. But if you're a stickler for taxonomy, it's worth knowing.
One of their most appealing features for display purposes is that adult males are often quite active during the day, running around on top of the substrate rather than hiding. This makes them much more visible than many roach species that only emerge at night. Females tend to be shyer and more inclined to burrow, but you'll still see them regularly.
Appearance and Behaviour
The transformation from nymph to adult is dramatic. Nymphs are solid brown with fine hairs giving them a slightly fuzzy appearance—they look like ordinary roach nymphs and spend nearly all their time underground. Adults emerge with that spectacular black-and-white domino pattern that makes the species famous.
Physical features:
Adults: Glossy black with bold white spots arranged like domino tiles
Females larger (up to 35mm) and broader than males (~25mm)
Hidden orange-yellow colouring on upper abdomen (visible if they raise wings)
Rounded, somewhat beetle-like body shape
Nymphs: Plain brown, hairy, unremarkable until final moult
Behavioural traits:
Crepuscular—most active at dawn and dusk, though adults often visible during the day
Strong burrowing instinct, especially nymphs and females
Adults can climb smooth surfaces; nymphs cannot
Cannot fly despite having wings
When disturbed, may raise wings and release alarm pheromones
Social—do best in groups rather than kept alone
Generally calm and tolerant of handling
Their calm nature and inability to fly or jump makes them suitable for handling and even appropriate for supervised interaction with children. They don't exhibit the frantic escape behaviour common to many roach species.
Basic Care
Domino Cockroaches are genuinely easy to keep, making them an excellent choice for beginners or anyone wanting a low-maintenance display species.
Temperature: Keep them between 21-29°C (70-85°F). They'll tolerate room temperature in most UK homes, but growth and breeding activity increases at warmer temperatures (24-29°C). Below 21°C they'll slow down significantly; below 18°C isn't recommended.
Humidity: They come from temperate rather than tropical climates, so they don't need high humidity. Air humidity of 40-60% is fine. However, they do need moist substrate—particularly for females to lay egg cases. Create a moisture gradient with damper areas at the bottom/back of the enclosure.
Ventilation: Moderate to high ventilation is important. Good airflow helps prevent stagnant conditions. Our screw-in air vents work well for creating proper ventilation in plastic tubs.
Substrate depth: Provide at least 5-8cm (2-3 inches) of substrate. Nymphs are dedicated burrowers and will spend the vast majority of their time underground—in the wild they can burrow up to 30cm deep during dry seasons. Adequate depth is essential for their wellbeing.
Climbing: Adults can climb glass and smooth plastic, so you'll need an escape-proof lid. A thin band of petroleum jelly around the top rim provides extra security. Nymphs cannot climb smooth surfaces, so they're not an escape risk.
Feeding
Domino Cockroaches are detritivores that primarily feed on decaying plant matter. They're not fussy eaters, though leaf litter should form the foundation of their diet.
Primary foods (always available):
Decaying hardwood leaf litter (oak is excellent)
This should always be present—nymphs especially will consume it continuously
Supplementary foods:
Vegetables: carrot, potato, sweet potato, courgette
Fruits: apple, orange, banana (for moisture as well as nutrition)
Protein: fish flakes, fish food pellets, bee pollen, dog/cat kibble
Insect jelly—clean, doesn't spoil, reportedly well-received
Calcium: While not as calcium-demanding as some invertebrates, providing cuttlebone or crushed eggshells supports healthy moulting.
They have symbiotic gut bacteria and flagellates (similar to termites) that help them digest cellulose from decaying plant matter. This makes leaf litter not just a food source but essential for their digestive health.
Habitat
A 10-gallon enclosure is sufficient for a well-established colony. Smaller containers (around 4 litres) work fine for starter cultures of 5-10 individuals.
Key requirements:
Secure, escape-proof lid (adults climb)
Deep substrate (5-8cm minimum) for burrowing
Layer of leaf litter on top of substrate
Cork bark pieces—provide climbing opportunities for males and additional cover
Branches or fake plants for adult males to explore (optional but appreciated)
Moisture gradient in substrate
Good ventilation
Unlike many roach species that need extensive hiding spots, Domino Cockroaches don't require elaborate hides since nymphs and females naturally burrow into the substrate. Adult males will appreciate some climbing surfaces and bark pieces, but the enclosure can be relatively simple.
Substrate Mix
A moisture-retentive substrate that supports burrowing is essential. Avoid sand—it's not suitable for this species.
Recommended mix:
Coconut fibre (coir) as a base
Organic potting soil or peat moss mixed in
Optional: cypress mulch for texture
Generous layer of hardwood leaf litter on top
Create a moisture gradient by keeping the substrate damper at one end (where it's deepest) and drier toward the surface at the other end. The damp areas are where females will deposit their egg cases. Mist when the top few inches dry out, but don't waterlog the substrate.
Breeding
Domino Cockroaches breed readily in captivity once their basic needs are met. They're oviparous—females produce oothecae (egg cases) rather than giving birth to live young.
Breeding characteristics:
Females produce up to 13 oothecae over their lifetime
Each ootheca contains 6-14 nymphs (some sources report up to 20-30)
Oothecae are deposited in moist leaf litter
Incubation takes approximately 2-3 months depending on temperature
Newborn nymphs are tiny (around 3mm—sesame seed sized)
Nymphs develop over several months before reaching adulthood
Breeding tips:
Ensure moist leaf litter is available—essential for egg deposition
Maintain humidity to prevent oothecae from drying out
Warmer temperatures (24-29°C) speed up development
Keep them in groups—they're social and breed better with company
Be patient—nymphs take several months to mature
Once established, colonies can become quite prolific. Since adults only live a few months while nymphs take longer to mature, you'll want to maintain overlapping generations to ensure there are always adults in the enclosure for display.
Interesting reproductive note: once a female has mated, she actively rejects other males, kicking them away with her hind legs. One mating is apparently sufficient.
Display Value
Domino Cockroaches are considered one of the best display roach species available:
Adults (especially males) are often visible during the day
Striking appearance that draws attention
Calm temperament allows for observation without them fleeing
Active enough to be interesting but not frantic
Work well in bioactive setups alongside springtails and isopods
Safe for children to observe and handle (supervised)
They're one of the few roach species that non-enthusiasts genuinely find attractive. If you want to change someone's mind about cockroaches, showing them an adult Domino Cockroach is a good place to start.
Who Are These Roaches For?
Domino Cockroaches suit:
Complete beginners to exotic roach keeping
Anyone wanting an attractive, visible display species
Keepers who want low-maintenance insects
Families with children interested in invertebrates
Bioactive setup enthusiasts
People who want to challenge negative perceptions of cockroaches
They're not ideal if:
You want instant visual impact—nymphs are plain brown
You're expecting to see them constantly (they do burrow)
You need fast-breeding feeder colonies (there are better options)
Domino Cockroaches have earned their reputation as the "gateway roach" that gets people interested in keeping cockroaches. They're beautiful, easy to care for, breed readily, and have enough interesting biology (beetle mimicry, crepuscular activity, burrowing behaviour) to keep you engaged. The wait for nymphs to mature into their adult colouration is worth it—there's something satisfying about watching that first plain brown nymph transform into a striking black-and-white adult.

Chrome Cockroach (Gyna Caffrorum)
£5.00
Gyna caffrorum is one of the more visually striking cockroaches available in the hobby. The common name "Chrome Cockroach" comes from their metallic, almost porcelain-like wing colouration—young adults display a distinctive blue-grey sheen that matures into silvery-white with mottled patterning. Combined with vivid orange legs and abdomen colouration that persists throughout life, they're genuinely attractive insects. Small, relatively easy to breed, and interesting to observe, they make an excellent introduction to the Gyna genus.
Species Information
Scientific name: Gyna caffrorum
Common names: Chrome Cockroach, Chrome Roach, Chrome Porcelain Roach, Ghost Porcelain Cockroach, Pink Cockroach
Origin: Southern Africa (South Africa, Mozambique, Zimbabwe, Botswana, Namibia, Angola, Swaziland)
Adult size: Males approximately 29–30mm, females approximately 34–35mm
Lifespan: Adults live 4–5 months; total lifecycle approximately 10–12 months
Difficulty: Easy
Appearance
Chrome Cockroaches go through a striking colour transformation as they develop:
Nymphs: Black and white peppered pattern, similar to the related species Gyna lurida
Young adults: Gorgeous blue-grey colouration with a metallic, almost chrome-like sheen
Mature adults: Silvery-white with mottled patterning on the wings
Throughout life: Vivid orange-red legs and abdomen colouration
Wings: Fully developed, patterned to camouflage with leaf litter
Body: Smooth, porcelain-like surface texture
Sexual dimorphism is noticeable—females are slightly larger and broader, while males are more slender and typically more active.
Behaviour
Burrowers: They spend much of their time buried in substrate—you won't always see them
Nymphs: Less shy than many Gyna species; more likely to be visible on the surface
Adults can climb: Smooth surfaces including glass and plastic (nymphs cannot climb)
Adults can fly: Capable of flight, especially when startled or at higher temperatures (nymphs cannot)
Fast: They're quick movers when disturbed
Nocturnal: Most active at night, though they may emerge during the day
Not heavy feeders: They eat less than you might expect for their size
The flight capability is worth emphasising—higher temperatures make adults more likely to take off. They're not constantly airborne, but an open enclosure at warm temperatures is asking for escapees.
Enclosure Setup
Escape Prevention
This is the single most important aspect of keeping Gyna caffrorum. Adults can both climb smooth surfaces and fly:
Use containers with tight-fitting lids
Apply a thick petroleum jelly (Vaseline) barrier around the top inside edge
Some keepers prefer front-opening enclosures—when adults fly, they fly upward toward the ceiling rather than outward
Be especially careful at higher temperatures when flight is more likely
The good news: escapees won't survive UK room conditions long-term. But preventing escapes is still essential.
Ventilation
Good airflow is important—they need moderate to high ventilation. This means:
Multiple vents or mesh panels
Avoid stagnant, overly humid conditions
Balance ventilation with humidity retention
Substrate
As burrowers, they need adequate substrate depth:
5–10cm of substrate
Coconut fibre (coco coir) works well as a base
Mix with decaying hardwood leaves and rotten wood pieces
Alternative: flake soil mixed with leaf litter (reported to increase breeding success and speed nymph development)
Keep substrate slightly moist but not wet
Hides and Structure
Cork bark pieces (horizontal and vertical)
Leaf litter layer on top
Branches for climbing and perching
They use leaf litter both as cover and as food
Don't overcrowd the enclosure—they appreciate space. Containers developed more in length than height work well since they spend most time at substrate level.
Temperature
Range: 21–29°C (70–85°F)
Optimal for breeding: 25–28°C (77–82°F)
Room temperature: Acceptable—they're more tolerant than some Gyna species
Winter: Can be kept as low as 18–20°C during winter months without issues
Higher temperatures (upper 20s°C) encourage breeding activity but also make adults more likely to fly. Find the balance that works for your setup.
Humidity
Range: 50–70%
Substrate: Keep slightly moist, not wet
Important: Avoid excessively high humidity—this species doesn't thrive in very humid conditions and can experience moulting problems
Humidity gradient: Many Gyna keepers recommend keeping roughly half the substrate moist and half drier
Misting: Light misting once or twice weekly, allowing some drying between
Gyna caffrorum is more forgiving about humidity than some relatives like G. centurio, but "moderate" is the key word—they don't want constant dampness.
Diet
Chrome Cockroaches are omnivores and not particularly fussy eaters:
Staples:
Leaf litter (main food source in the wild)
Dry dog or cat food
Fish flakes
Fresh foods:
Fruits: banana, apple, mango (they particularly enjoy sweet, soft fruits)
Vegetables: carrot, courgette, cucumber
Protein sources:
Dog/cat biscuits
Fish flakes
Bee pollen
Avoid:
Solanaceous plants (potato, tomato, pepper)
Very acidic fruits (lemon, grapefruit, pomegranate)
They're not heavy eaters compared to some cockroach species. Protein is important—inadequate protein can slow development and may lead to cannibalism in some Gyna species, though caffrorum is less prone to this than some relatives.
Breeding
Gyna caffrorum breed readily in captivity—they're considered one of the easier Gyna species:
Reproduction: Ovoviviparous—females retain eggs internally and give birth to live nymphs
Litter size: Potentially large—some sources report up to 200 nymphs per clutch, though typical numbers are lower
Birth pattern: Females don't usually give birth to all nymphs at once; they produce several smaller litters from one ootheca over a few months
Ootheca: Females typically produce only one ootheca in their lifetime, which they retain internally
Development: Nymphs take approximately 4–6 months to reach adulthood
Adult lifespan: 4–5 months (females tend to live slightly longer than males)
Breeding Tips
Keep temperatures in the optimal range (25–28°C)
Ensure adequate protein in the diet
Don't overcrowd—give them space
Maintain the humidity gradient (half moist, half drier)
Males typically mature before females—this is normal for the genus
Using flake soil in the substrate has been reported to increase breeding success and speed up nymph development, if you want to optimise production.
Care Summary
Temperature: 21–29°C (25–28°C optimal for breeding)
Humidity: 50–70%, moderate—avoid excess moisture
Substrate: 5–10cm deep, coconut fibre with leaves and rotten wood
Ventilation: Good airflow required
Diet: Leaf litter, fruits, vegetables, protein sources
Escape prevention: Critical—adults climb and fly
Breeding: Ovoviviparous, potentially large litters, 4–6 month development
Difficulty: Easy
Comparison with Other Gyna Species
Gyna caffrorum is often recommended as a starter species for the genus:
Easier than G. centurio: More forgiving of humidity and temperature variations
Easier than G. capucina: The "Pink Roach" is notoriously difficult; caffrorum is far more reliable
Similar to G. lurida: Both are relatively straightforward, with similar nymph colouration
If you're interested in the Gyna genus but haven't kept them before, caffrorum is a sensible starting point before moving to more demanding species.
Feeder Use
Chrome Cockroaches can work as feeders due to their manageable size and breeding rate. However:
Their attractive appearance means many keepers prefer them as display animals
Adult climbing and flight ability makes colony management more demanding than non-climbing species
Other species (dubia, red runners) may be more practical for pure feeder production
They're popular in bioactive setups where their burrowing behaviour and appearance add interest beyond simple clean-up crew function.
Who Are They For?
Gyna caffrorum suit:
Beginners to the Gyna genus: More forgiving than most relatives
Display keepers: The colour progression from nymph to adult is genuinely attractive
Bioactive enthusiasts: Good size, interesting behaviour, visually appealing
Experienced keepers: Low-maintenance compared to many exotic species
The main requirement is secure housing—if you can prevent escapes, they're straightforward to keep and breed. Their tolerance for varying conditions makes them more suitable for UK room temperatures than some tropical species, though supplemental heating will encourage breeding.

Shadow Cockroach (Pynoscelus Nigra)
£10.00
The Shadow Cockroach is a sleek, jet-black roach species from Southeast Asia, named for its dark, shadowy appearance. Unlike flashier ornamental roaches, Pycnoscelus nigra is valued for its understated look, hardy nature, and remarkably easy care requirements. This parthenogenetic species—meaning females reproduce without males—makes colony establishment straightforward and population growth reliable. Whether you're keeping them as display animals, bioactive cleanup crew, or feeder insects, Shadow Cockroaches are a practical and attractive choice.
Species Information
Scientific name: Pycnoscelus nigra
Common names: Shadow Cockroach, Shadow Roach
Origin: Southeast Asia
Adult size: 2.5–3cm (approximately 1 inch)
Lifespan: 1–2 years
Care level: Easy—hardy and beginner-friendly
Appearance
Shadow Cockroaches are almost entirely jet-black, giving them their "shadow" name. They're closely related to the Surinam Cockroach (Pycnoscelus surinamensis) but distinguished by their darker overall colouration. Look for red-orange legs contrasting against the black body—this colour difference is one of the easiest ways to tell them apart from their Surinam cousins.
Adults reach around 2.5–3cm, making them a medium-small roach species. They have a rounded, compact body shape typical of burrowing roaches. While adults can climb smooth surfaces like glass and plastic, they're slow-moving and poor flyers despite having wings—escapes are manageable with basic precautions.
Behaviour
Shadow Cockroaches are dedicated burrowers. They spend most of their time beneath the substrate surface, emerging primarily to feed. Don't expect to see them constantly—they're shy and prefer staying hidden. When they do surface, they move slowly and deliberately rather than darting around.
This burrowing nature makes them peaceful enclosure inhabitants. They won't compete aggressively with other species and integrate well into multi-species setups. They're non-aggressive, non-invasive, and pose no threat to plants or other invertebrates in bioactive enclosures.
Parthenogenetic Reproduction
One of the most notable features of Pycnoscelus nigra is parthenogenesis—females reproduce without mating, essentially cloning themselves. This means:
All-female colonies: The entire population consists of females (males are extremely rare and sterile when they do appear)
Single roach can start a colony: One individual is enough to establish a breeding population
Steady population growth: Females can produce 30–36 offspring approximately once per month
Reliable breeding: No need to worry about male-female ratios or mating success
This reproductive strategy makes Shadow Cockroaches excellent for anyone wanting to establish a self-sustaining colony without the complexity of managing breeding pairs.
Enclosure Setup
Container
A secure plastic container with ventilated lid works well. Shadow Cockroaches can climb smooth surfaces, so ensure your enclosure has a tight-fitting lid or use a barrier like petroleum jelly around the upper rim. Good ventilation prevents excess humidity buildup while maintaining the moisture they prefer.
Substrate
Deep substrate is essential—these are burrowing roaches that spend significant time underground. Provide at least 5–10cm depth of:
Organic topsoil
Coco coir (coconut fibre)
Or a mix of both
Keep the substrate lightly moist but not waterlogged. Shadow Cockroaches aren't particularly fussy about substrate humidity, but they do best with consistently damp conditions that support their burrowing lifestyle.
Hides and Décor
Cork bark pieces
Egg crate sections (positioned vertically to increase floor space)
Leaf litter scattered on substrate surface
Pieces of rotting wood
While they'll primarily use the substrate itself for hiding, surface-level cover gives them options and makes the enclosure more naturalistic.
Temperature and Humidity
Temperature
Optimal range: 24–28°C (75–82°F)
Acceptable range: Room temperature to low 30s°C
Breeding: Higher temperatures (high 20s to 30°C) encourage faster reproduction
They tolerate room temperature but breed more prolifically with supplemental heat. A heat mat on one side of the enclosure works well if your ambient temperature runs cool.
Humidity
Preference: High humidity
Substrate: Keep lightly moist
Ventilation: Maintain airflow to prevent stagnation
Shadow Cockroaches are adaptable regarding humidity—they're not as demanding as some tropical species. Keep things damp rather than wet, and they'll do fine.
Diet
Shadow Cockroaches are unfussy eaters. Offer a varied diet including:
Staples:
Leaf litter (oak, maple, birch)
Vegetable scraps (carrot, potato, squash, leafy greens)
Fruit pieces (apple, banana, melon—remove before moulding)
Supplements:
Fish flakes or dry roach chow for protein
Dog or cat biscuits (dry)
Rotting wood pieces
They're excellent at gut-loading if you're using them as feeders—whatever you feed them passes on to whatever eats them. Remove uneaten fresh food before it moulds to maintain enclosure hygiene.

While not the most colourful roach species, Shadow Cockroaches have an understated elegance. Their jet-black appearance and calm demeanour make them interesting to observe, particularly when they emerge to feed. They're a good choice for keepers who appreciate subtle beauty over flashy colours.
Bioactive Cleanup Crew
Shadow Cockroaches work well in bioactive enclosures alongside isopods and springtails. Their burrowing behaviour helps aerate substrate, and they'll consume waste, decaying plant matter, and leftover food. They're peaceful enough to coexist with other cleanup crew species without competition issues.
Their burrowing nature means they integrate into substrate rather than competing for surface space with isopods. They're a useful addition to bioactive setups for larger reptiles or amphibians where additional waste processing is beneficial.
Feeder Insects
Shadow Cockroaches make excellent feeders for:
Reptiles (bearded dragons, geckos, monitors)
Amphibians (larger frogs, salamanders)
Tarantulas and other arachnids
Large invertebrates
Their soft bodies, appropriate size (2.5–3cm adults, smaller nymphs available for smaller predators), and excellent gut-loading capacity make them nutritious prey items. The parthenogenetic reproduction ensures steady supply once a colony is established.
Comparison to Surinam Cockroach
Shadow Cockroaches (P. nigra) and Surinam Cockroaches (P. surinamensis) are closely related and share many characteristics:
Both are parthenogenetic
Both are burrowing species
Both have similar care requirements
Both reach similar adult sizes
The main differences:
Colour: Shadow Cockroaches are darker overall (jet-black vs. brown)
Leg colour: P. nigra has distinctive red-orange legs
Abdominal segment: The last ventral segment is more distinct in P. nigra
Care requirements are essentially identical between the two species.
Care Summary
Temperature: 24–28°C (room temperature acceptable, warmer for faster breeding)
Humidity: High—keep substrate lightly moist
Substrate: Deep (5–10cm+) soil or coco coir for burrowing
Diet: Vegetables, fruit, leaf litter, protein supplements
Ventilation: Moderate—prevent stagnation while maintaining humidity
Climbing: Yes—adults can climb smooth surfaces
Flying: Poor flyers despite having wings
Reproduction: Parthenogenetic (females only, no males needed)
Breeding rate: 30–36 offspring per female, approximately monthly
Important Notes
Escape potential: Can climb glass/plastic and may establish in houseplants if escaped—use secure enclosures with barriers
Burrowing: Will spend most time underground—don't expect constant surface activity
Colony growth: Parthenogenesis means rapid population expansion once established
Multi-species compatible: Peaceful species that works well with other invertebrates
Who Are They For?
Shadow Cockroaches suit:
Beginners: Hardy, forgiving, and easy to breed
Feeder breeders: Reliable reproduction and good gut-loading capacity
Bioactive keepers: Useful cleanup crew addition for larger setups
Collectors: Attractive species for diverse roach collections
They're not ideal if you want highly visible, active display animals—their burrowing nature means most activity happens out of sight. But for practical purposes (feeders, bioactive, easy breeding), they're hard to beat.
Shadow Cockroaches offer reliable, low-maintenance roach keeping with the bonus of parthenogenetic reproduction. One roach becomes many with minimal effort, making them a practical choice whether you're feeding reptiles, stocking bioactive enclosures, or simply want an interesting invertebrate colony that largely takes care of itself.

Banana Cockroach (Panchlora Nivea)
£6.00
The original "green banana roach," Panchlora nivea stands out as one of the most successful and adaptable species in the exotic roach hobby. Their soft, pale green coloration and excellent breeding productivity have made them a staple for both display colonies and as nutritious feeders for larger reptiles and amphibians. While perhaps not as brilliantly colored as their cousin P. magnifica, these hardy roaches offer beginners an accessible entry into keeping green roaches with their forgiving care requirements and reliable reproduction.
A Glimpse
Origin: Cuba, Caribbean, and now pantropical
Scientific Name: Panchlora nivea
Difficulty Level: Low
Adult Size: 22-25mm (0.9-1 inch)
Rarity: Common in hobby
Temperature: 75°F to 85°F (24°C to 29°C)
Humidity: 65% to 75%
Favorite Foods: Fruits, vegetables, grains
Supplements: Fish flakes, bee pollen, oats
Overview
Cuban Cockroaches have a fascinating history, having spread from their Caribbean origins to tropical regions worldwide through human commerce - particularly the banana trade, hence their nickname. Adults display a pleasant lime to pale green color that's less metallic than other Panchlora species but still attractive. Nymphs start brown and gradually develop their green coloration through successive molts, with the transformation beginning around the third or fourth instar.
Despite being excellent climbers and capable fliers, they're surprisingly manageable in captivity with proper precautions. They're primarily nocturnal but less skittish than many roach species, often remaining visible during daylight hours in established colonies. Adults emit a distinctive but mild odor when disturbed - some describe it as musty or cucumber-like - but proper ventilation keeps this minimal.
Basic Care
Enclosure Setup:
Minimum 15-litre container for starter colonies (10-15 individuals)
Secure, fine-mesh ventilation essential - adults can fly
3-4 inch substrate layer for nymphs
Mix of horizontal and vertical hides
Egg cartons, cork bark, or cardboard tubes work well
Apply petroleum jelly barrier below lid as escape prevention
Substrate Mix:
40% coconut fiber
30% peat moss or compost
20% crushed dried leaves
10% sand or perlite
Environmental Conditions: Cuban Cockroaches are notably tolerant of varying conditions, part of what makes them excellent for beginners. They thrive at normal room temperatures (22-26°C) but breed faster with slight warming. Humidity should be moderate - they're more forgiving of occasional dry periods than many tropical species. Mist every 2-3 days, or provide a moisture gradient with one damp corner. Good ventilation is crucial to prevent fungal issues and minimize any odor.
Feeding: Feed 2-3 times weekly with a varied diet. They're unfussy eaters with robust appetites. Dry foods like fish flakes, dog kibble, and rolled oats should always be available. Fresh fruits and vegetables are eagerly consumed - apple, orange, carrot, and potato are favorites. They have a particular fondness for sweet foods and will swarm over banana or melon. Grains and cereals are excellent for boosting reproduction. Remove uneaten fresh foods within 48 hours.
Breeding Notes
P. nivea are prolific breeders under proper conditions. Females produce oothecae containing 20-30 eggs, which they carry briefly before depositing in substrate or hidden crevices. Incubation takes 40-50 days at optimal temperatures. Nymphs grow quickly, reaching maturity in 3-4 months with good nutrition. Adults live 12-20 months, with females capable of producing multiple oothecae throughout their lives. Colonies can grow rapidly - be prepared for population management or have a plan for excess roaches.
Special Considerations
Their climbing and flying abilities require secure enclosures - double-check all ventilation and apply barriers. While they cannot establish in UK homes due to temperature requirements, they're hardy enough to survive temporary escapes, so vigilance is important. They're excellent as feeders due to their soft bodies and high protein content, making them popular for poison dart frogs and small chameleons.
This species cohabits well with other roaches and clean-up crew invertebrates. They're particularly good in bioactive setups where their active foraging helps prevent food waste accumulation. While generally healthy, overcrowding can lead to stress and reduced breeding - maintain appropriate colony sizes or split regularly.
The mild odor they produce is completely harmless but can be minimized through good ventilation and regular cleaning. Some keepers report that adding activated carbon to the substrate helps absorb any smells. Their relatively small size and green color make them less intimidating than larger roach species, potentially helping nervous keepers overcome their hesitations about keeping roaches.

Headlight Cockroaches (Lucihormetica Verrucosa)
£2.00
Headlight Cockroaches (Lucihormetica verrucosa), also known as Warty Glowspot Roaches, are one of the more visually interesting cockroach species available in the hobby. Native to Venezuela and Colombia, these burrowing roaches get their common name from the two distinctive yellow-orange spots on the males' pronotum—they genuinely look like tiny headlights. Females lack these spots and tend to be slightly larger.
What makes this species particularly fascinating is that in the wild, those headlight spots are reportedly bioluminescent, glowing thanks to symbiotic bacteria the roaches consume. In captivity, they don't glow—whatever bacteria causes this effect isn't present in captive-bred colonies. It's a shame, but the spots are still striking enough to make males stand out.
These are calm, slow-moving roaches that spend most of their time buried in substrate. They're not the flashiest species you'll find, but they're genuinely easy to keep and make decent display animals for anyone interested in something a bit different from the standard isopod fare.
A Glimpse
Origin: Venezuela & Colombia, South America
Scientific Name: Lucihormetica verrucosa
Difficulty Level: Easy
Size: Up to 4cm (adults)
Temperature: 22-28°C
Humidity: 60-70%
Rarity: Common
Favourite Foods: Leaf litter, decaying wood, vegetables, fruits
Supplements: Protein (fish flakes, dog/cat kibble), calcium sources
Overview
Lucihormetica verrucosa belongs to the family Blaberidae and is sometimes called the Warty Glowspot due to the small bumps or "warts" on the exoskeleton. They're a medium-sized cockroach species that's been in the hobby for years, popular with keepers who appreciate their docile temperament and interesting appearance.
Males are the showstoppers here—their pronotum features two prominent yellow to orange spots that really do resemble car headlights. The rest of the body is dark brown to black with a white margin around the dorsal plates. Interestingly, if you feed them lots of carrots, the spots can deepen to orange or even red due to carotenoid accumulation.
These roaches are fossorial, meaning they spend most of their time buried. Don't expect them to be wandering around on the surface constantly—they're shy creatures that prefer to hide during the day and become active at night. When you do see them out, they're notably slow-moving and calm compared to many cockroach species, making them one of the better species for handling if that's your thing.
Appearance and Behaviour
Adults reach approximately 3-4cm in length. Males are slightly smaller than females but are easily identified by those characteristic headlight spots on their pronotum. Females are plain by comparison—dark brown/black without the spots.
Nymphs are small, shiny, and jet-black when young, developing their adult colouration through successive moults. Older nymphs display attractive orange markings on their thorax before reaching adulthood.
Behaviourally, these are quiet, undemanding roaches:
Primarily nocturnal—most active at night and early morning
Strong burrowing instinct—they'll dig down into substrate and stay hidden
Calm temperament—they don't panic or dart around when handled
Adults can climb smooth surfaces like glass; nymphs cannot
Not aggressive feeders—they won't mob food like some species
One thing to note: adults can climb glass and smooth plastic, so you'll need a secure lid. Some keepers apply a thin layer of petroleum jelly around the top of the enclosure as extra insurance. Nymphs don't climb, so escapes are mainly an adult concern.
Basic Care
Headlight Cockroaches are genuinely easy to keep, making them suitable for beginners to exotic invertebrates.
Temperature: Keep them between 22-28°C. Room temperature in most UK homes works fine, though they'll be more active and breed faster at the warmer end of this range. Avoid cold spots and sudden temperature drops.
Humidity: Moderate humidity around 60-70% suits them well. They like a moisture gradient—keep one side of the enclosure slightly damp while the other remains drier. This allows them to regulate their own hydration needs.
Ventilation: Good airflow is important. These aren't humidity-demanding species that need sealed enclosures. Ventilation holes or mesh-covered openings work well. Our screw-in air vents are ideal for creating proper airflow in plastic tubs.
Substrate depth: This is important—provide at least 8-10cm (3-4 inches) of substrate. These are burrowing roaches that spend significant time underground. Shallow substrate will stress them. Deeper is better.
Feeding
Headlight Cockroaches are detritivores with modest appetites. They're not the voracious eaters that some roach species are, so don't expect them to demolish food overnight.
Primary foods:
Dead oak leaves and other hardwood leaf litter (essential, always available)
Decaying wood and bark
They seem to prefer leaf litter over other foods
Supplementary foods:
Vegetables: cucumber, courgette, carrot, pumpkin, sweet potato
Fruits: apple, banana, orange (in moderation)
Protein: fish flakes, dog/cat kibble, dried shrimp
Calcium: Provide a calcium source like cuttlebone or crushed eggshells. While not as calcium-demanding as some invertebrates, it supports healthy moulting.
They're not big eaters, so feed sparingly and remove uneaten fresh food within a day or two to prevent mould and pest issues.
Habitat
Any well-ventilated container with a secure lid works. Plastic tubs are practical for breeding colonies; glass terrariums work for display setups.
Key requirements:
Deep substrate (minimum 8-10cm) for burrowing
Cork bark or wood pieces for surface hides
Leaf litter covering the substrate
Moisture gradient—damp corner with moss, drier areas elsewhere
Good ventilation
Secure lid (adults climb)
Substrate Mix
A moisture-retentive substrate that allows for burrowing is essential.
Recommended mix:
Coconut fibre or coir as a base
Organic topsoil (pesticide-free)
Sphagnum moss mixed in for moisture retention
Decaying wood pieces
Generous layer of leaf litter on top
Keep one section of the substrate slightly damp by misting, while allowing other areas to dry out more. Cork bark pieces on the surface provide additional hiding spots for any roaches that venture topside.
Breeding
Lucihormetica verrucosa breeds reasonably well in captivity, though they're not the fastest reproducers. They're ovoviviparous—females carry eggs internally and give birth to live nymphs.
Courtship is an involved process. Males use their antennae and palps to stimulate females, and mating can last around an hour when successful. Females become receptive about twenty days after their final moult, once their exoskeleton has fully hardened.
For breeding success:
Maintain temperatures at the higher end of their range (25-28°C)
Ensure deep substrate for gravid females
Keep humidity consistent
Provide adequate nutrition, including protein
Don't disturb them excessively
Nymphs are tiny when born and will burrow immediately. Growth is steady but not rapid—expect several months before juveniles reach maturity.
As Feeders
While primarily kept as display animals, Headlight Cockroaches can work as feeders for larger reptiles like monitor lizards. Their calm nature and inability to climb (as nymphs) makes them easy to manage. However, their slow breeding and burrowing habits mean they're not ideal for high-volume feeder production—there are more efficient species for that purpose.
Who Are These Roaches For?
Headlight Cockroaches suit:
Keepers looking for an easy-care exotic roach species
Anyone wanting something calmer than typical darting cockroaches
Hobbyists interested in burrowing species
Those who appreciate unusual invertebrates
Beginners to exotic roach keeping
They're not for you if:
You want highly visible, active roaches
You're after fast-breeding feeder colonies
You expect them to glow (they won't in captivity)
Headlight Cockroaches won't win any awards for being the most exciting roaches in the hobby—they spend most of their time buried, after all. But for keepers who appreciate a calm, easy species with interesting sexual dimorphism and a bit of natural history behind them, they're well worth considering. The males really do look like they have little headlights, and that alone makes them a conversation piece.

Centurion Porcelain Cockroaches (Gyna Centurio)
£2.00
Centurion Porcelain Cockroaches (Gyna centurio), also known as Chrome Porcelain Roaches, are one of the prettiest cockroach species you'll find in the hobby. Native to West and Central Africa, adults sport a smooth, elegant shape with beautiful splashes of cream, maroon, and brown across their pronotum and wings—genuinely attractive insects that look nothing like the pest roaches people imagine when they hear "cockroach."
They're part of the Gyna genus, a group known for their clean, porcelain-like appearance and live-bearing reproduction. What makes centurio particularly appealing is the combination of stunning adult colouration and easy care requirements. They're prolific breeders too—females can produce up to 200 nymphs from a single brood, so colonies can grow quickly once established.
One important thing to know: adult Gyna can both climb and fly. They're not aggressive about it, but when startled or when the enclosure is opened, adults may take short flights. This means escape-proofing your setup is essential. Nymphs, however, cannot climb or fly and spend most of their time burrowed in substrate—you won't see much of them until they mature.
A Glimpse
Origin: West & Central Africa (Cameroon, DRC, Gambia region)
Scientific Name: Gyna centurio
Common Names: Centurion Roach, Chrome Porcelain Roach, Gambia Roach
Difficulty Level: Easy to Moderate
Size: 2.5-3.5cm (females slightly larger)
Temperature: 24-30°C (75-86°F)
Humidity: 40-60% (air), moist substrate
Rarity: Moderate
Favourite Foods: Leaf litter, fruits, vegetables, protein supplements
Overview
Gyna centurio belongs to the family Blaberidae and is sometimes known by its old name Gyna sp. "Gambia" from before it was formally described. They're one of several Gyna species in the hobby, alongside relatives like G. lurida (the classic "Porcelain Roach"), G. caffrorum (Chrome Roach), and G. capucina (Pink Roach).
What distinguishes centurio from its cousins is its particular colour pattern—the cream, maroon and brown markings give them a distinctive look that some keepers describe as "chrome-like." They're considered one of the easier Gyna species to keep and breed, being less fussy about humidity than some relatives and tolerating slight crowding better than others.
Like all Gyna, they're ovoviviparous—females retain eggs internally and give birth to live nymphs rather than depositing oothecae. This is always satisfying to witness, as you'll suddenly discover tiny nymphs appearing in the substrate without having to worry about incubating egg cases.
Appearance and Behaviour
The contrast between nymphs and adults is significant. Nymphs are dark-coloured, somewhat plain, and spend nearly all their time buried in substrate—you'll rarely see them. Adults emerge with their characteristic smooth, porcelain-like wings displaying those attractive cream, maroon, and brown patterns.
Physical features:
Adults: Smooth, graceful shape with cream/maroon/brown patterned wings
Females slightly larger and broader (up to 3.5cm) than males
Males more slender, active, and prone to flying
Nymphs: Darker colouration, wingless, burrowing
Flattened, oval body shape typical of Gyna
Behavioural traits:
Adults can climb smooth surfaces—escape prevention essential
Adults can fly—short, somewhat erratic flights, especially when startled
Nymphs cannot climb or fly—dedicated burrowers
Generally shy—prefer to burrow and hide
Males more active and visible than females
Most active during evening/night hours
Voracious eaters, especially fond of fruit
The flying ability is the main thing that sets Gyna apart from many other pet roach species. It's not constant—they won't be buzzing around the enclosure—but when disturbed or when the lid is opened, adults may launch into brief flights. Higher temperatures make them more likely to fly. This is something to be aware of but shouldn't put you off; with proper precautions, escapes are easily prevented.
Basic Care
Centurion Porcelain Cockroaches are relatively forgiving compared to some Gyna species, making them a good entry point into the genus.
Temperature: Keep them between 24-30°C (75-86°F). They can survive at room temperature in UK homes, but growth and breeding slow significantly below 24°C. Warmer temperatures (26-30°C) encourage faster development and more prolific breeding. Be aware that higher temperatures also make adults more flighty.
Humidity: Air humidity of 40-60% is fine—they don't need tropical conditions. However, the substrate should be kept moderately moist (not wet). Create a moisture gradient with one side damper than the other. Avoid over-moistening; they don't like swampy conditions.
Ventilation: Good airflow is important. Use well-ventilated enclosures—but ensure all ventilation holes are too small for adults to squeeze through or are covered with fine mesh. Our screw-in air vents work well when properly sized.
Substrate depth: Provide at least 5-8cm of substrate. Nymphs are dedicated burrowers and will spend nearly all their time underground. Adult females also burrow, especially when gravid. Only adult males regularly hang about on the surface.
Escape prevention: This is critical. Adults climb and fly, so you need:
A secure, tight-fitting lid with no gaps
A barrier of petroleum jelly or silicone grease around the top rim
Caution when opening the enclosure—consider doing so inside a larger container or room where escapees can be recaptured
The good news: even if one escapes, they cannot survive UK household conditions and won't establish as pests.
Feeding
Centurion Porcelain Cockroaches are omnivorous and not particularly fussy. They're actually quite voracious eaters compared to some roach species.
Primary foods (always available):
Hardwood leaf litter (oak, beech)—essential staple
Decaying wood
Supplementary foods:
Fruits: They love fruit—banana, apple, orange, peach, berries
Vegetables: carrot, courgette, sweet potato
Protein: fish flakes, fish food pellets, bee pollen, dog/cat kibble
Beetle/insect jelly—clean, doesn't spoil, well-received
Feeding tip: Don't use deep food bowls—nymphs may not be able to access them and could starve. Scatter food on the substrate surface or use very shallow dishes. Remove uneaten fresh food within a day or two to prevent mould and mite issues.
Avoid citrus fruits, which may be harmful, and be careful not to overfeed protein, as Gyna can resort to cannibalism if conditions become crowded or food-stressed.
Habitat
A medium-sized, well-ventilated enclosure with a secure lid is essential. Plastic containers work well for breeding colonies; glass terrariums are fine but require extra attention to escape prevention.
Key requirements:
Secure, escape-proof lid (absolutely essential)
Petroleum jelly barrier around upper rim
Deep substrate (5-8cm minimum) for burrowing
Generous layer of leaf litter
Cork bark pieces for climbing/hiding
Moisture gradient—damper on one side
Good ventilation (but escape-proof)
For a starter colony, a container around 4-10 litres is sufficient. As the colony grows (and it will grow quickly), you may need to upgrade or split the population.
Note on crowding: Gyna centurio tolerates crowding better than some relatives, but severe overpopulation can cause problems including sudden die-offs. Monitor colony size and be prepared to thin numbers if needed.
Substrate Mix
A moisture-retentive substrate that allows for burrowing is essential.
Recommended mix:
Coconut fibre (coir) as a base
Organic topsoil or peat moss mixed in
Generous layer of hardwood leaf litter on top
Cork bark pieces for surface hides
Keep the substrate moderately humid but not wet—damp to the touch, not soggy. Create a moisture gradient by misting one end more than the other. The damper areas are where females prefer to give birth.
Avoid sand, as it's not suitable for this species.
Breeding
Centurion Porcelain Cockroaches are prolific breeders—one of their main appeals. They're ovoviviparous, meaning females retain eggs internally and give birth to live nymphs.
Breeding characteristics:
Females give birth to live nymphs (no egg cases to incubate)
Broods can be huge—up to 200 nymphs per female
Females don't usually give birth to all nymphs at once; they produce several smaller litters over time
Females likely only produce one internal ootheca in their lifetime
Nymphs mature in approximately 4-6 months
Adults live 4-5 months (females tend to live longer than males)
Males typically mature before females
Breeding tips:
Keep temperatures at the higher end (26-30°C) for faster breeding
Ensure females aren't stressed—stress can cause them to abort their developing ootheca
Avoid severe overcrowding
Provide plenty of food—they eat a lot, and hungry roaches may cannibalise
Maintain moderate substrate moisture for successful births
Important timing note: Because males often mature before females and adults don't live very long (a few months), there can be timing issues in small colonies where males die before females are ready to mate. Starting with a decent number of individuals (10-15+) helps ensure you have males and females maturing at overlapping times.
Comparing Gyna Species
Several Gyna species are available in the hobby. Here's how centurio compares:
Species
Common Name
Notes
G. centurio
Centurion/Chrome Porcelain
Easy, prolific, cream/maroon/brown colouration
G. lurida
Porcelain Roach
Classic species, hobby staple, yellow/tan adults, very prolific
G. caffrorum
Chrome Roach
Larger, more colourful, nymphs more active/visible
G. capucina
Pink Roach
More finicky, females sensitive to stress, pink colouration
Gyna centurio is one of the easier and more forgiving species in the genus—a good starting point if you're new to Gyna.
Who Are These Roaches For?
Centurion Porcelain Cockroaches suit:
Keepers wanting beautiful display roaches
Anyone interested in live-bearing cockroach species
Those who want prolific breeding potential
Keepers comfortable managing climbing/flying species
People looking for an entry into the Gyna genus
They're not ideal if:
You want a "set and forget" species with no escape risk
You're uncomfortable with insects that can fly
You want constantly visible roaches (nymphs burrow, adults are shy)
You can't maintain warm temperatures (breeding slows significantly below 24°C)
Centurion Porcelain Cockroaches offer a great combination of beauty and breeding potential. Yes, the flying ability requires some extra precautions, but with a properly secured enclosure, they're perfectly manageable. The reward is watching those stunning adults emerge and eventually witnessing females produce swarms of tiny live nymphs. For keepers ready to step beyond basic roach species, they're an excellent choice.
