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.

Simandoa cave roach (Simandoa Conserfariam)
from £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: Low to Moderate
Adult Size: 20-25mm (0.8-1 inch)
Rarity: High (Conservation Dependent)
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.

from £10.00
Here's a realistic product description for your Emerald Cockroach:
Emerald Cockroach (Panchlora magnifica)
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: Moderate to Advanced
Adult Size: 25-30mm (1-1.2 inches)
Rarity: Medium to High
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.
