A premium fermented substrate crafted from European hardwoods, perfect for isopods, millipedes, and beetle larvae. Flake Soil is a specially prepared breeding substrate made from crushed, milled, and fermented oak and beech wood. Through a careful composting process, the wood breaks down into a nutrient-rich, easy-to-digest material that invertebrates thrive on. This 1L portion is ideal for hobbyists wanting to try flake soil without committing to larger quantities, or for topping up existing enclosures. What is Flake Soil? Unlike standard substrates, flake soil has been pre-fermented—meaning the tough cellulose and lignin in the wood has already begun breaking down. This makes it far more digestible for detritivores and provides a ready source of nutrition. The fermentation process also encourages beneficial microorganisms that support a healthy enclosure ecosystem. Ideal for: Isopods – Works brilliantly as part of a substrate mix for Cubaris species and other tropical varieties. Combine with coconut coir, sphagnum moss, and leaf litter for an enriched environment that supports burrowing behaviour and healthy moulting. Millipedes – An excellent primary substrate for millipede keeping, providing both nutrition and a comfortable medium for burrowing. Beetle larvae – Originally developed for rhinoceros beetle and stag beetle breeding, flake soil remains the gold-standard substrate for rearing larvae to their full potential. How to Use Flake soil is supplied slightly dried for storage stability. Before use, gradually add dechlorinated water and mix thoroughly until you achieve the desired moisture level—it should hold together when squeezed but not drip. Allow it to rest for 24 hours before introducing your invertebrates. For isopod enclosures, flake soil works best as part of a layered substrate. Use it alongside your existing mix to add variety and nutrition. It pairs perfectly with springtails in bioactive setups, as both will work together to process organic matter and maintain a clean, balanced environment. Specifications Volume: 1 Litre & 2.5 Litre Composition: Fermented European hardwood (primarily oak and beech) Moisture: Approximately 50-60% (may vary slightly) Fibre content: Approximately 25% Storage Store in a cool, dry place. If the substrate dries out during storage, simply rehydrate before use. Properly stored flake soil will keep for several months. Whether you're keeping Porcellio, Armadillidium, or building a bioactive vivarium, flake soil is a versatile addition to your supplies. Grab a bag and see the difference quality substrate makes.

A Glimpse Scientific Name: Porcellio werneri "Silverback" Common Names: Greek Shield Isopod, Pancake Isopod, Werner's Woodlouse Family: Porcellionidae Origin: Greece — rocky, dry habitats on the Aegean islands and surrounding areas Adult Size: Up to 20 mm Difficulty: Medium — not a beginner species, but manageable if you understand what they need Temperature: 17–26°C (room temperature is fine) Humidity: 50–65% — this is a dry-habitat species Ventilation: Medium to high — good airflow is important Diet: Leaf litter, rotting white wood, vegetables, protein supplements, moss, lichen Supplements: Cuttlebone, crushed limestone, or oyster shell — calcium is important Breeding: Seasonal — only 1–2 broods per year What Makes Werneri Special Porcellio werneri is one of the most visually distinctive isopods you can keep. Forget the usual rounded woodlouse shape — these are flat. Remarkably flat. The body is broad, disc-like, and shield-shaped, with a wide white or cream skirt edging the dark central body. They look like tiny flying saucers, or — as the common name suggests — miniature Greek shields. The "Silverback" variety adds to this with a prominent silvery-white stripe running down the centre of the back, creating even more contrast against the dark body. It's a naturally occurring variation from a distinct wild population, not a selectively bred morph, which gives it a slightly different character to the standard grey P. werneri. The flat body shape isn't just aesthetic — it's a functional adaptation. In their native Greece, these isopods inhabit rocky, dry limestone habitats where being able to press flat into crevices and under stones is a survival advantage. In captivity, you'll see them doing exactly the same thing — gripping flat against cork bark, wedged into narrow gaps, or pressed against the sides of hides. It's a very different behaviour from rounder isopod species and it's fascinating to watch. Enclosure A standard culture tub (12 litre) is sufficient for a starter colony, but P. werneri benefits from more space than many isopod species for an important reason: adult males can be territorial. They may squabble with other males, and in a cramped enclosure this can become a problem. A 25 litre tub gives a more established colony room to spread out and reduces conflict. Provide plenty of hides — cork bark pieces (both flat and curved), stone pieces, and stacked structures work well. The flat body shape means these isopods will use very narrow gaps that other species can't fit into, so thin crevices between cork bark pieces or flat stones are particularly appreciated. Consider arranging hides at different heights. Using a taller enclosure with stacked or raised structures gives the isopods the ability to self-regulate their position relative to the moisture gradient — closer to the damp substrate when they need moisture, higher up in drier air when they don't. Substrate and Humidity This is where P. werneri differs significantly from most isopods you might have kept. They're a dry-habitat species. The natural habitat is rocky, calcareous limestone terrain in Greece — not tropical forest floor. In practical terms, this means keeping the enclosure drier than you would for most other species. No more than a third of the substrate should be damp at any time. A patch of moist sphagnum moss in one corner provides a hydration zone they can visit when needed, but the majority of the enclosure should be dry to moderately dry. The substrate itself should be organic topsoil with leaf litter and crumbled white rotten wood. Keep it on the drier side overall. The moisture gradient is critical — damp at the bottom, dry on the surface, with a distinct wet patch in one area and the rest left dry. Good ventilation supports this. Airflow helps prevent the enclosure from becoming too humid and reduces the risk of mould, which thrives in the stagnant, damp conditions that would stress this species. Mesh vents in the lid or upper sides of the enclosure are the simplest way to achieve this. An important note: dry doesn't mean bone dry. All isopods need access to moisture for respiration and moulting. The goal is a predominantly dry enclosure with reliable access to a small damp area — not a desert. Getting this balance right is the main skill involved in keeping P. werneri. Temperature 17–26°C — which, for most UK houses, is simply room temperature. No additional heating or lighting is needed in the majority of situations. Avoid placing the enclosure in direct sunlight or near radiators, which can dry things out too aggressively and cause temperature spikes. These isopods are comfortable across a fairly wide temperature range, which is one of the things that makes them more manageable than their reputation might suggest. Diet The primary diet is leaf litter and decaying white rotten wood, both of which should always be available in the enclosure. Interestingly, P. werneri reportedly prefers more aged, well-decayed leaves over fresher ones — so don't worry about replacing leaf litter the moment it starts breaking down. That's when they want it most. Supplement with root vegetables (sweet potato, carrot, yam) and other veg. Protein is important — offer fish flakes, dried shrimp, or freeze-dried bloodworm once or twice a week. Calcium should always be available: cuttlebone is the simplest option. Remove uneaten fresh food before it moulds. In a drier enclosure this is slightly less urgent than with tropical species, but still good practice. Breeding Here's the thing that sets P. werneri apart from most Porcellio species you might be used to: they're seasonal breeders. While most Porcellio will breed continuously if conditions are right, werneri typically only produce 1–2 broods per year. This is a significant difference and it means colony growth is slow. This isn't a fault in your husbandry — it's the natural reproductive strategy of the species. In their native Greek habitat, they've adapted to breed in response to seasonal cues rather than breeding constantly. In captivity, you can't really override this with warm temperatures or extra food. They breed on their own schedule. The practical implication is that starting with 5 is fine, but you shouldn't expect the rapid colony expansion you'd get from something like P. scaber or P. laevis. Building a large colony takes time — potentially years rather than months. This is part of why they remain rare and relatively expensive despite being well-established in the hobby. Male Territoriality Worth mentioning separately because it's unusual for isopods: adult male P. werneri can be territorial and may fight with other males. This is rarely a serious problem in a well-sized enclosure with plenty of hides, but it's something to be aware of. Providing enough structure and space for males to establish their own areas reduces conflict. In a small, bare container with too many adult males, you may see aggression. Being Realistic At £40 for 5, P. werneri Silverback sits at a mid-range price point. The difficulty rating of Medium is fair for captive bred stock — these aren't as demanding as Ardentiella or challenging Cubaris species, but they do require you to understand and manage a dry setup, which is the opposite of what most isopod care guides teach. If you've only kept tropical or temperate species that like it damp, the adjustment to a dry-habitat species is the main learning curve. The instinct to mist regularly and keep things humid will work against you with werneri. If you can resist that instinct and trust the moisture gradient approach, they're perfectly manageable. The slow breeding is the other factor to consider. If you want a colony that fills out quickly and gives you the satisfaction of rapid growth, this isn't the species for that. If you're happy with a slower-paced, more deliberate keeping experience where each new brood feels like an event, werneri is genuinely rewarding.

Leopard Bee Isopods represent one of the most visually captivating species emerging from the biodiverse Philippines, combining eye-catching spotted patterns with the robust character typical of the remarkable Filippinodillo genus. These medium-sized tropical beauties have earned their common name through distinctive leopard-like markings accented with bee-inspired yellow tones, creating a stunning appearance that elevates any collection beyond ordinary species. Species Overview Place of Origin: PhilippinesGenus: FilippinodilloSpecies: Filippinodillo sp. "Leopard Bee" Key Care Requirements Maintenance Effort: MediumIdeal Temperature Range: 72°F-80°F (22°C-27°C)Reproduction Rate: ModerateVentilation: Medium to HighGeneral Size: 15-20mmRarity Level: Very RareHumidity Range: 70%-80%Preferred Diet: Hardwood, tropical leaf litter, protein supplementsEssential Supplements: Limestone chunks, cuttlefish bone, calcium powder Natural Habitat and Behaviour In the lush tropical forests of the Philippines, Leopard Bee Isopods inhabit the moisture-rich microhabitats beneath decomposing hardwood logs and thick accumulations of leaf litter. These island environments provide the perfect combination of high humidity, stable warm temperatures, and abundant organic matter that these remarkable creatures require to thrive. Like other members of the Filippinodillo genus, Leopard Bee Isopods display confident, exploratory behaviour compared to more secretive species. They actively forage through substrate layers and navigate complex terrains with purpose, making them engaging subjects for observation. Their conglobation ability—rolling into a protective ball when startled—provides both defensive capability and entertainment value for dedicated keepers. These isopods serve essential roles as ecosystem engineers in their native habitats, breaking down substantial amounts of organic matter and returning vital nutrients to the forest floor. Understanding these natural behaviours helps recreate appropriate conditions in captivity, ensuring successful bioactive vivarium setups that mirror their wild environments. Physical Characteristics Leopard Bee Isopods showcase the impressive size and robust build characteristic of Philippine Filippinodillo species. Their medium to large bodies typically reach 15-20mm in length, providing substantial presence without the space demands of truly giant varieties. Their most distinctive feature remains the striking spotted pattern that gives them their leopard designation. Rich brown to chocolate base coloration provides canvas for irregular creamy-yellow spots distributed across their armoured segments, creating natural camouflage that becomes stunning ornamentation in captivity. The bee-inspired yellow tones add warmth to their appearance, distinguishing them from other spotted isopod varieties. The heavily calcified exoskeleton displays characteristic thickness associated with conglobating species, requiring significant calcium intake to maintain. Their segmented bodies show clear demarcation between pereon segments, creating visual interest as they move through their environment. Diet and Nutrition As specialized detritivores adapted to nutrient-rich Philippine forests, Leopard Bee Isopods require diverse feeding programmes that reflect their tropical origins. Their natural diet consists primarily of decomposing hardwoods—particularly tropical varieties—along with the thick leaf litter layers characteristic of Southeast Asian forests. Provide a foundation of quality hardwood pieces including oak, beech, and any available tropical woods. Cork bark serves dual purposes as both hiding structure and supplemental food source, making it invaluable in their setups. Calcium supplementation proves absolutely critical for maintaining their impressive exoskeletons. Provide limestone chunks, cuttlefish bone pieces, and crushed oyster shell throughout the substrate. Protein requirements remain moderate but important for colony health. Offer high-quality fish flakes, dried shrimp, or specialized isopod protein foods 2-3 times weekly. Creating the Perfect Enclosure Successfully housing Leopard Bee Isopods requires replicating the warm, humid conditions of Philippine tropical forests. Start with well-ventilated containers of at least 6-8 quart capacity for starter cultures. Substrate depth should reach 6-8cm minimum to accommodate their burrowing behaviours. Create a base layer using quality organic topsoil mixed with decomposed hardwood matter. Avoid products containing fertilizers, pesticides, or coconut-based materials. Layer substantial amounts of hardwood leaf litter over the base substrate, creating the thick accumulations these isopods encounter in nature. Add cork bark pieces, hardwood chunks, and limestone rocks throughout to create complex environments. Temperature and Humidity Management Maintain enclosures between 72-80°F (22-27°C), with 74-78°F representing the ideal range. Temperature stability proves more important than achieving specific numbers—avoid dramatic fluctuations that stress colonies. Humidity management requires careful attention with these tropical species. Maintain 70-80% relative humidity through regular misting with dechlorinated water. Create moisture gradients by keeping one enclosure section slightly drier. Breeding and Colony Development Leopard Bee Isopods reproduce at moderate rates once established. Females typically produce broods of 10-20 offspring after 6-8 week gestation periods in their marsupial pouches. Sexual maturity arrives at approximately 4-6 months under optimal conditions. Creating breeding-conducive environments requires maintaining consistent temperature and humidity levels, providing abundant high-quality foods, and minimizing disturbances. Care Difficulty and Considerations Leopard Bee Isopods fall firmly into the medium to advanced difficulty category, making them inappropriate for absolute beginners. Their tropical requirements demand attention to environmental parameters that more forgiving temperate species tolerate. However, experienced keepers familiar with tropical isopod care fundamentals find them rewarding subjects. Those new to isopod keeping should gain experience with hardy species before attempting Leopard Bee Isopods. Understanding fundamental care principles with forgiving varieties builds skills necessary for success with these demanding tropical beauties. Why Choose Leopard Bee Isopods? These remarkable Philippine natives represent outstanding additions for intermediate to advanced collectors seeking distinctive species that command attention. Their leopard-and-bee inspired patterning creates visual interest surpassing most common varieties. Whether expanding existing isopod collections or seeking centerpiece species for tropical display setups, Leopard Bee Isopods deliver exceptional value through their combination of beauty, behaviour, and breeding potential.

A Glimpse Scientific Name: Cubaris sp. Common Name: Albino Ducky (Rubber Ducky variant) Family: Armadillidae Origin: Thailand — limestone cave systems Adult Size: 15–20 mm Difficulty: Medium-Hard — not the hardest Cubaris, but not a beginner species either Temperature: 22–28°C Humidity: 70–85% Ventilation: Medium — cross-ventilation important but enclosure should retain moisture well Diet: Leaf litter, rotting wood, vegetables, protein supplements, moss, lichen Supplements: Cuttlebone, crushed limestone — calcium is critical for this genus Albino Ducky: Overview The Rubber Ducky isopod is probably the most famous isopod in the hobby. Discovered in limestone caves in Thailand in 2017, the original Rubber Ducky Cubaris sp. kicked off what's sometimes called the "Cubaris craze" — a surge of interest in exotic isopod morphs that's still going strong. The distinctive duck-like face and warm yellow-brown colouration made them instantly iconic. Since then, a number of colour variants have emerged in the hobby: Blonde Ducky, White Ducky, Black Lip Ducky, Pink-Faced Ducky (Pak Chong), and others. The Albino Ducky is part of this family of variants — a lighter, paler form that lacks the typical pigmentation of the standard morph. In albino individuals, the dark body pigments are reduced or absent, leaving a much lighter overall appearance while retaining the characteristic Rubber Ducky body shape and proportions. As with many newer Cubaris variants, "Albino Ducky" is a trade name rather than a formal taxonomic designation. All Ducky variants share fundamentally the same care requirements, so whether you've kept standard Rubber Duckies, Blonde Duckies, or other variants before, the husbandry will be familiar. What Makes Rubber Ducky Types Different to Keep Rubber Ducky-type Cubaris have a few characteristics that set them apart from other Cubaris species and from isopods in general: Deep burrowers. These isopods spend significant periods fully submerged in the substrate, especially during moulting. This is normal behaviour, not a sign of stress. You may not see your isopods for days or even weeks at a time, particularly early on as they settle in. This is one of the most common sources of worry for new Ducky keepers — the temptation to dig them up to check on them is strong, but resist it. Disturbing a moulting isopod can kill it. Slow breeders. Even by Cubaris standards, Ducky-type isopods breed slowly. Brood sizes are small (typically 1–10 mancae), generation times are long, and colony growth is gradual. Some keepers report needing months for a colony to acclimate before breeding begins. This is the main reason Ducky variants remain expensive despite being well-established in the hobby — you simply can't produce them quickly. Limestone cave origins. Like other Thai Cubaris, Ducky-types originate from limestone cave environments. Providing limestone or calcium-rich materials in the enclosure isn't just a supplement — it mimics their natural habitat and seems to noticeably improve how settled and active the colony is. Enclosure A sealed plastic container (6–12 litre) with ventilation holes works well for a starter culture. Cross-ventilation is important — holes on opposite sides — but the enclosure should retain humidity well. A clip-lock tub with drilled ventilation is the standard approach. Ducky-types don't need large enclosures, and a smaller space can actually be easier to manage humidity-wise. A shoebox-sized container is fine for a group of 5 to start. As the colony grows (slowly), you can move up. Substrate This is arguably the most important element. Provide deep substrate — at least 8–10 cm, ideally deeper. Ducky-type Cubaris burrow extensively, and substrate depth directly affects their ability to moult safely and feel secure. If your substrate is too shallow, they can't exhibit natural behaviour and may fail to thrive. Use organic topsoil mixed with crumbled white rotten hardwood and leaf litter. Oak and beech leaves work well. The substrate and leaf litter are a major part of the diet, so quality matters — this isn't just bedding, it's food. Limestone is essential. Add pieces of limestone, crushed oyster shell, or cuttlebone throughout the enclosure. Some keepers use limestone cave stone or Texas holey rock as both hides and calcium sources. The isopods will graze on limestone surfaces and it helps with moulting. Cubaris from cave environments have evolved with constant access to calcium-rich rock, and providing it makes a noticeable difference to colony health. Create a moisture gradient: one end consistently damp (sphagnum moss patch), the other end drier. This lets the isopods choose their preferred humidity level. Cork bark pieces provide hides at the surface for animals that aren't currently burrowed. Temperature and Humidity 22–28°C is the target range. In a UK house, room temperature in summer will often be sufficient. In cooler months, a heat mat on a thermostat may be needed — placed on the side of the enclosure, not underneath (you don't want to cook the substrate where isopods are burrowing and moulting). Humidity should be maintained at 70–85%. The sealed container approach helps hold humidity naturally. Mist lightly when the surface starts to dry, but don't waterlog the substrate. Soggy conditions promote mould and bacterial growth that can crash a colony. The deep substrate should hold moisture at the bottom even when the surface is relatively dry — this is the gradient the isopods need. Ventilation is a balancing act. Enough airflow to prevent stagnant air and mould, but not so much that the enclosure dries out rapidly. Start with fewer ventilation holes and add more if you see condensation covering every surface or mould developing. Diet The substrate itself (leaf litter and rotting wood) is the primary food source. Keep it well stocked. Supplement with: Vegetables: Cucumber, courgette, sweet potato, carrot — in small amounts Protein: Dried shrimp, fish flakes, freeze-dried bloodworm, or fish food pellets — Cubaris are protein-hungry compared to most other isopod genera. Offer protein once or twice a week Calcium: Cuttlebone permanently available, plus limestone in the enclosure Moss and lichen: Eaten and appreciated Some keepers report that Ducky-types are less interested in fresh vegetables than other Cubaris and prefer to graze on substrate, leaf litter, and protein supplements. Your mileage may vary — offer a variety and see what gets eaten. Remove uneaten fresh food within a day to prevent mould. In a warm, humid enclosure, food spoils quickly. Breeding Patience is the word. Ducky-type Cubaris can take months to acclimate to a new enclosure before breeding begins. Once established, they breed year-round but slowly — small broods, long intervals. A starting group of 5 gives a reasonable chance of both sexes being represented, but don't expect rapid colony growth. The keys to breeding success are the same as for general health: consistent warmth, appropriate humidity, deep substrate for burrowing, abundant calcium, and minimal disturbance. The last point is particularly important — repeatedly opening the enclosure, digging through substrate, or rearranging hides stresses Cubaris and can suppress breeding. A colony that is left alone, checked on weekly rather than daily, and kept consistently will outperform one that's fussed over constantly. Colour Stability in Albino Lines A note worth including: with any albino or reduced-pigment isopod line, there can be some variation in how strongly the albino trait expresses across individuals and generations. It's been observed across multiple Cubaris types that body colour in captivity can shift somewhat from what's seen in the wild or in breeding stock, possibly influenced by diet, environment, or genetics. If you're keeping Albino Duckies specifically for their reduced pigmentation, maintaining them as a separate line (not mixed with standard Duckies or other variants) preserves the trait most reliably. Being Realistic About the Price At £120 for 5, Albino Ducky is one of the most expensive isopods on the site. The price reflects genuine rarity — this is a less common variant of an already slow-breeding species. If you haven't kept Cubaris before, starting here would be a costly experiment. Standard Rubber Duckies or a more established Cubaris like Panda King would let you learn the genus at a lower financial risk. The care isn't dramatically harder than other Cubaris species, but the combination of slow breeding, burrowing behaviour (which can make it hard to assess colony health), and the financial stakes of getting it wrong means prior Cubaris experience is strongly recommended. If you have kept Ducky-type Cubaris before and you're adding the Albino variant to your collection, the care will hold no surprises. Set up identically to your existing colonies, keep conditions consistent, and give them time

  Scientific Name: Ophistreptus guineensis Common Name: African Giant Chocolate Millipede Family: Spirostreptidae Origin: West Africa — Ghana, Nigeria, and surrounding regions (dry savannah habitats with distinct rainy and dry seasons) Adult Size: Up to 25–26 cm — this is a large species Lifespan: 7–10 years with good care Difficulty: Easy — hardy and forgiving Temperature: 24–28°C (can tolerate higher, up to 30°C) Humidity: 60–80% — notably drought-tolerant for a tropical millipede Activity: Surface-active, good climbers, often visible during the day Diet: Leaf litter, rotting wood, fruit, vegetables, moss Supplements: Cuttlebone, crushed limestone, or oyster shell for calcium Chocolate Millipedes: Overview The Chocolate Millipede is one of the larger species available in the UK hobby, growing up to 25–26 cm as an adult. The name is straightforward — they're a rich, warm chocolate-brown to reddish-tan colour throughout, with a glossy sheen that catches the light. They closely resemble Archispirostreptus gigas (the African Giant Black) in overall body shape and proportions, but where the AGB is dark and sometimes a bit dull-looking, Chocolates have a warmth and lustre to them that makes them genuinely striking. They originate from the dry savannah regions of Ghana and Nigeria, which makes them notably different from many tropical millipedes in one important way: they're drought-tolerant. In the wild, they experience distinct dry and rainy seasons rather than constant tropical humidity. This translates into an animal that's more forgiving of humidity fluctuations in captivity than many other species — which is a significant advantage for less experienced keepers or anyone who sometimes forgets to mist. Like the Ghana Speckled Legs (T. aoutii) that we also stock, Chocolate Millipedes are active and surface-dwelling. They'll climb on branches, cork bark, and enclosure furniture, and they spend a lot of time above ground rather than permanently buried in the substrate. Combined with their size, this makes them one of the more visually rewarding millipede species to keep. Enclosure These are large millipedes and they need space. A minimum enclosure size of 60x20 cm floor space is the baseline, but bigger is better, particularly if you're keeping a group. A large plastic storage box with ventilation, a converted aquarium, or a glass terrarium all work. Provide thick branches for climbing — Chocolates will use them. Cork bark pieces, both horizontal and angled, give hides and climbing surfaces. The enclosure should be secure, especially if you're keeping juveniles, which are smaller and better at escaping than you'd expect. Ventilation is needed but doesn't have to be as elaborate as for some humidity-sensitive species. A few ventilation holes or a mesh section in the lid will do. Substrate Depth should be at least 10 cm, ideally deeper for adults — the general rule with millipedes is substrate depth at least equal to the animal's body length for safe moulting. For a 25 cm millipede, that's a serious depth of substrate, so factor this into your enclosure planning. Use organic topsoil (pesticide-free, fertiliser-free) mixed with crumbled white rotten hardwood and dried leaf litter. Oak and beech leaves are both good. The substrate forms a major part of their diet — they eat it — so this isn't just bedding, it's food. Top with a thick layer of whole leaves, moss, and additional pieces of soft rotting wood. Keep the substrate moist to the touch but not saturated. These millipedes are more tolerant of drier conditions than many species, but they still need access to moisture. Their mouthparts aren't strong enough to chew hard, dry material — humidity keeps the wood and leaves soft enough for them to eat. A completely dry substrate means they can't feed properly, even if there's plenty of organic material available. Temperature and Humidity 24–28°C is the target range, with some sources recommending up to 30°C. These are warm-climate millipedes that appreciate higher temperatures than some other species. In a UK house, a heat mat on a thermostat will almost certainly be needed. As with all burrowing millipedes, place the heat mat on the side of the enclosure above the substrate line, never underneath. Humidity should be maintained at around 60–80%. The drought tolerance of this species gives you more margin for error than with something like Centrobolus, but don't take that as permission to let things dry out completely. A moderate level of misting — once every few days, or when the top layer of substrate starts drying — will keep things in the right range. Diet Chocolate Millipedes are enthusiastic and unfussy eaters. The substrate (leaf litter and rotting wood) is their primary food and should always be well stocked. On top of that, they'll happily take a wide range of fruit and vegetables. Favourite foods from keeper experience include cucumber, melon, banana, oranges, and cooked sweetcorn. Moss and lichen are also eaten and appreciated. Calcium should always be available — cuttlebone, crushed limestone, or oyster shell. This is especially important for growing juveniles and breeding females. Protein can be offered occasionally — fish flakes or similar. Remove uneaten fresh food within a day or two to prevent mould. Breeding Chocolate Millipedes will breed in captivity, but there's a detail worth knowing: breeding often seems to be triggered by simulating seasonal changes. In the wild, these animals experience dry periods followed by wet periods, and replicating this cycle — allowing the enclosure to dry out slightly for a few weeks, then increasing misting and humidity — can stimulate egg-laying. Males can be identified by the modified legs (gonopods) on the seventh body segment. Mating is conducted face to face, and pairs can remain coupled for extended periods. An important point about the young: leave them with the adults. Juvenile Chocolate Millipedes feed on the frass (droppings) of the adults, which provides them with essential gut bacteria they need to properly digest their food. Separating them too early can be detrimental. Sexing Males have their legs on the seventh body segment replaced by gonopods — specialised reproductive structures that are tucked into pouches. On females and immature animals, the seventh segment has normal legs. This is the most reliable way to sex any Spirostreptid millipede. Handling These are calm, gentle millipedes that tolerate handling well once accustomed to it. They're not aggressive and won't bite. When startled, they'll either walk backwards toward cover or curl into a defensive coil. Like all millipedes, they can secrete defensive chemicals — and Chocolate Millipedes are reportedly noted for producing a faintly chocolate-like scent, which is where some people trace the common name from (though the colour is the more obvious explanation). Wash your hands after handling. The secretion can stain skin temporarily and may irritate sensitive areas. Lifespan and Expectations This is where Chocolate Millipedes really stand out. With good care, they can live 7–10 years — significantly longer than many other commonly available species. That's a genuine long-term commitment, but it also means you get more from the relationship than with shorter-lived species. A well-maintained group can provide years of observation and breeding. Growth is slow. Juveniles go through many moults over a long period before reaching adult size, doubling their length along the way. Don't expect a baby to become a 25 cm adult in a few months — this is a species that rewards patience. Taxonomic Note It's worth mentioning that there's some uncertainty in the hobby about whether everything sold as Ophistreptus guineensis is actually a single species. The recorded distribution of O. guineensis according to scientific databases doesn't always match the collection localities reported in the hobby (Ghana/Nigeria/Cameroon), and it's possible that multiple species within the genus are being sold under the same name. For practical keeping purposes this doesn't change the care advice, but it's an honest reflection of where the taxonomy currently stands.

A Glimpse Scientific Name: Cubaris sp. Common Name: Cappu Cream Family: Armadillidae Origin: Thailand Adult Size: Up to approximately 20 mm Difficulty: Medium Temperature: 24–29°C Humidity: 75–85% Diet: Leaf litter, rotting wood, vegetables, protein supplements, moss, lichen Supplements: Cuttlebone or crushed limestone for calcium — essential for Cubaris Cappu Cream: Overview Cappu Cream is one of a growing number of coffee-themed Cubaris sp. morphs originating from Thailand. As with many of these newer trade-named varieties, specific documentation on this exact morph is limited — "Cappu Cream" doesn't appear widely in keeping databases or care guides as a separately established variety. What we can say is that it belongs to the broader group of Thai Cubaris that also includes Cappuccino, Latte, and similar coffee-inspired morphs, and its care requirements follow established Cubaris sp. husbandry. That's worth being upfront about. If you're buying these expecting to find a detailed species-specific care sheet online, you won't find one. What you will find is solid, well-tested care information for Thai Cubaris as a group, and that's what this description is based on. Like other Cubaris from Thailand, these isopods originate from limestone cave environments and the surrounding tropical forest floor. They're adapted to warm, humid conditions with access to calcium-rich substrates — understanding this natural habitat is the key to keeping them successfully. Enclosure A sealed plastic container (such as a 6-litre clip-lock box) with ventilation holes works well for a starter culture of 5. This is one of those setups where the balance between humidity retention and airflow matters — you need both. Drill or melt small ventilation holes in the lid or upper sides, but not so many that the enclosure dries out quickly. Cross-ventilation (holes on opposite sides) helps prevent stagnant air, which is a common cause of colony crashes in Cubaris. As the colony grows, move up to a larger container. There's no rush with Cubaris — they don't breed explosively, so a small starting enclosure won't become overcrowded for a long time. Substrate and Setup Provide a deep substrate layer — at least 7–8 cm. Cubaris like to burrow, and substrate depth gives them the humidity gradient they need (damper at the bottom, drier at the surface). Use organic topsoil mixed with crumbled white rotten hardwood and leaf litter. Oak and beech leaves work well. The substrate and leaf litter form a significant part of their diet, so quality matters. Limestone is important. Thai Cubaris originate from karst cave systems where limestone is everywhere. Adding pieces of limestone, crushed oyster shell, or cuttlebone to the enclosure provides both calcium for moulting and mimics their natural environment. Many keepers report that Cubaris are noticeably more settled and breed better when limestone is present — it's not just a supplement, it's habitat enrichment. Create a moisture gradient across the enclosure: keep one end consistently damp (a patch of sphagnum moss works well for this) and allow the other end to stay drier. This lets the isopods choose their preferred humidity level at any given time. Add cork bark pieces for hides. Cubaris appreciate enclosed spaces to retreat into, and cork bark is light, natural, and holds moisture well. Temperature and Humidity 24–29°C is the target range. These are tropical isopods that need warmth to thrive and breed. In a UK house, you'll likely need a heat mat on a thermostat during cooler months. Room temperature in summer may be sufficient depending on your home. Humidity should stay between 75–85%. The sealed container setup helps maintain this — mist lightly when the surface starts to look dry, but don't waterlog the substrate. Soggy conditions are as dangerous as dry ones for Cubaris. The moisture gradient mentioned above is your best tool here. Ventilation matters alongside humidity. Stagnant, humid air encourages mould and bacterial growth that can wipe out a colony. The goal is humid but not stuffy. Diet The substrate itself (leaf litter and rotting wood) is the primary food source — keep it well stocked and replenished as it breaks down. Supplement with: Vegetables: Cucumber, courgette, sweet potato, carrot — offered in small amounts Protein: Dried shrimp, fish flakes, or freeze-dried bloodworm — Cubaris are noticeably more protein-hungry than many other isopod genera. Offer protein once or twice a week Calcium: Cuttlebone left permanently in the enclosure, or crushed limestone/oyster shell mixed into the substrate Moss and lichen: Eaten and appreciated Remove uneaten fresh food within a day to prevent mould. In a warm, humid Cubaris enclosure, food spoils quickly. Breeding Cubaris as a genus breed more slowly than Porcellio or Porcellionides species. Expect smaller broods, longer intervals between them, and slower growth to maturity. This is normal — it's why Cubaris morphs tend to be more expensive than common isopod species, and it's why starting with 5 gives you a reasonable foundation without expecting overnight colony growth. Consistent warmth, humidity, and good nutrition are the keys to breeding success. Cubaris that are stressed, too cold, or underfed will simply stop reproducing. The most common mistake is inconsistency — allowing conditions to fluctuate significantly between checks. Patience is genuinely the main requirement. A healthy colony will grow, but on Cubaris time, not Porcellio time. What to Expect at £90 At £90 for 5, Cappu Cream sits in the premium Cubaris price range alongside other rare Thai morphs. For that investment, it's worth being realistic about what you're getting into. If you've successfully kept other Cubaris species — Cappuccino, Rubber Ducky, Panda King, or similar — you already understand the care requirements and the pace of colony growth, and Cappu Cream won't present any surprises. The care is fundamentally the same. If Cubaris is new to you, these aren't the ideal starting point. The combination of specific environmental needs (warmth, humidity, ventilation balance, limestone) and slow breeding means mistakes are expensive and slow to recover from. Consider starting with a more established and less costly Cubaris morph to learn the genus first, then move to rarer varieties once you're confident in your setup. A Note on Naming The isopod hobby has a lot of coffee-themed Cubaris morphs — Cappuccino, Latte, Cappu Cream, and others. These are trade names rather than scientific classifications, and the boundaries between them aren't always clearly defined. If you're collecting multiple coffee-themed morphs, it's worth keeping them in separate enclosures to maintain the integrity of each line, even if they look similar. Crossbreeding between morphs can produce offspring that don't reliably express either parent's colouration.

These underground sanctuaries provide the perfect combination of high humidity, stable temperatures, and abundant calcium sources from the surrounding limestone geology that these remarkable creatures require to thrive. Like their standard Rubber Ducky cousins and other Cubaris species, Helios specimens are naturally shy and secretive creatures. They spend much of their time burrowing deep through substrate layers and hiding beneath cork bark, emerging primarily during nighttime hours to forage for food. This fossorial behaviour makes them excellent candidates for bioactive vivarium setups where they can fulfil their natural role as ecosystem engineers. The limestone cave environment has shaped every aspect of their biology—from their calcium-dependent exoskeletons to their preference for complete darkness and their remarkable burrowing abilities. Understanding these natural behaviours helps recreate appropriate conditions in captivity, ensuring successful bioactive terrarium setups that mirror their wild environments. Physical Characteristics Helios Rubber Ducky Isopods display the characteristic charm that has made Rubber Ducky species so incredibly popular among collectors worldwide. Their most distinctive feature remains the endearing duck-like facial structure—when viewed head-on, their rounded head profile and eye placement create an uncanny resemblance to a rubber duckling's face, a trait that captured global attention following their discovery in 2017. What sets Helios apart from standard Rubber Ducky morphs is their distinctly lighter, golden-yellow coloration. Where typical specimens display rich yellows and oranges, Helios individuals showcase brighter, sun-kissed tones that give them their "sunny" designation. This luminous quality makes each sighting particularly rewarding, as their brilliant coloration contrasts beautifully against darker substrate and leaf litter. Adult Helios Rubber Ducky Isopods typically reach 12-15mm in length, making them substantial enough to observe their fascinating behaviours whilst remaining manageable in captive environments. Their segmented bodies feature the smooth, rounded profile characteristic of all Cubaris species, allowing them to roll into perfect spheres when threatened—earning them classification as true "pill bugs" within the Armadillidiidae family. The exoskeleton displays a glossy, almost polished appearance that enhances their visual appeal. Sexual dimorphism becomes apparent in mature specimens, with females showing slightly broader builds to accommodate their marsupial pouches. These physical differences assist dedicated breeders in colony management and selective breeding programmes. Diet and Nutrition As natural detritivores adapted to cave environments, Helios Rubber Ducky Isopods play a crucial ecological role in breaking down organic matter. In captivity, their diet should reflect the materials they encounter in their natural limestone cave habitats. The foundation of their diet consists of softwood and well-aged hardwood pieces. Unlike species preferring harder woods, Rubber Ducky isopods particularly appreciate softer, partially decomposed wood that they can more easily process. Providing varied wood sources ensures consistent nutrition as they gradually consume these materials. Leaf litter forms an essential component of their feeding programme. Offer generous layers of quality hardwood leaves—oak, beech, and magnolia work excellently. The thick litter layers not only provide ongoing nutrition but also create the dark, protected environments these cave-dwelling species instinctively seek. Calcium supplementation is absolutely critical for Helios Rubber Ducky Isopods—even more so than many other species. Their limestone cave origins mean they've evolved expecting constant access to calcium-rich materials. Provide limestone chunks, powdered calcium, cuttlefish bone, and crushed eggshells liberally throughout their enclosure. Insufficient calcium leads to failed molts, weakened exoskeletons, and poor reproductive success. Protein sources support healthy moulting and reproduction. Offer high-quality fish flakes, dried shrimp, or specialized isopod pellets 2-3 times weekly. Some keepers successfully use freeze-dried insects or quality fish food as protein supplements. Their protein requirements remain moderate but consistent. Supplement sparingly with organic vegetables such as carrots, sweet potatoes, and squash. However, their primary nutrition derives from wood and leaf litter rather than fresh produce. Remove uneaten fresh foods within 24-48 hours to prevent mold issues in the high-humidity environment these species require. Creating the Perfect Enclosure Successfully keeping Helios Rubber Ducky Isopods requires replicating their natural cave environment with exceptional attention to detail. These are not forgiving species—environmental lapses quickly result in colony decline, making proper setup essential from the beginning. Start with well-ventilated containers of at least 6-8 quart capacity for starter cultures. Proper ventilation proves crucial despite high humidity requirements—create multiple airflow holes covered with fine mesh to maintain air circulation whilst preventing escapes and retaining necessary moisture levels. The substrate must be deep—at least 15cm (6 inches) minimum—to accommodate their extensive burrowing behaviour. Helios Rubber Ducky Isopods are fossorial specialists that spend much time underground, particularly during molting periods. Shallow substrate causes stress and prevents natural behaviours essential for their wellbeing. Create your base substrate using quality organic topsoil mixed with decomposed hardwood matter and well-aged leaf mold. Avoid any products containing fertilizers, pesticides, or unnecessary additives. The substrate should feel like rich forest soil—moist but structured, allowing tunneling without collapsing. Layer generous amounts of softwood pieces, cork bark, and additional leaf litter throughout. These materials serve triple duty as food sources, hiding spots, and structural support for their tunnel systems. As they consume and process these materials, regular replacement maintains both nutrition and environmental complexity. Limestone incorporation proves essential—mix crushed limestone throughout the substrate and place larger chunks on the surface. This recreates the calcium-rich geology of their natural caves whilst providing ongoing dietary supplementation. Cork bark pieces, ceramic caves, and additional wood create dark refuges mimicking cave conditions. Consider aesthetic presentation whilst prioritizing function. These stunning isopods deserve display-worthy environments, though their shy nature means sightings remain precious moments. Creating viewing windows or strategic cork bark placement allows observation opportunities without compromising their need for darkness and security. Temperature and Humidity Management Helios Rubber Ducky Isopods require consistently warm temperatures reflecting their tropical Thai origins. Maintain enclosures between 75-82°F (24-28°C), with the warmer end of this range promoting activity and breeding behaviours. Temperature stability proves absolutely critical—avoid fluctuations exceeding 2-3°F daily, as instability stresses colonies and impairs reproduction. Room temperature typically falls short for optimal care. Heat mats placed on enclosure sides (never bottoms, which create dangerous hot spots) provide gentle supplemental warmth. Always use thermostats—overheating quickly proves fatal in sealed, high-humidity environments. Monitor temperatures using reliable thermometers placed at substrate level where isopods actually experience conditions. Humidity management represents perhaps the most critical aspect of Helios Rubber Ducky care. These cave specialists require very high humidity levels of 80-90%—substantially higher than most isopod species. The consistently moist cave environments they evolved in mean they possess limited desiccation resistance compared to surface-dwelling varieties. Maintain humidity through regular misting with dechlorinated water, but create slight moisture gradients by keeping one small section marginally drier. This allows individuals to self-regulate whilst ensuring overall conditions remain suitably moist. The substrate should feel consistently damp throughout—squeeze-testing should yield moisture without excessive water drainage. Deep substrate layers help maintain stable humidity by creating moisture reservoirs that resist rapid drying. The burrowing nature of these isopods means they can access deeper, more consistently moist substrate layers during their active periods. However, adequate ventilation prevents stagnant air despite extreme humidity—this delicate balance requires careful monitoring and adjustment. Monitor humidity using reliable hygrometers, though substrate observation often provides better practical guidance. If substrate surfaces begin drying between mistings, increase frequency. Conversely, if standing water appears or substrate feels muddy, improve ventilation and reduce watering. Finding the perfect balance takes time but proves essential for success. Breeding and Colony Development Helios Rubber Ducky Isopods reproduce at slow to moderate rates—substantially slower than prolific species like Porcellio varieties. Patience proves essential when establishing breeding colonies, as rapid population growth should never be expected. This slower reproduction partly explains their high value and ongoing rarity in the hobby. Females carry eggs in specialized marsupial pouches for approximately 6-8 weeks before releasing miniature juveniles. Broods typically contain 5-15 offspring, with exact numbers depending on female size, age, and environmental conditions. The specialized reproductive strategy ensures high juvenile survival rates, though the limited brood sizes mean population expansion progresses gradually. Sexual maturity arrives at 6-8 months under optimal conditions, though some individuals require longer development periods. Breeding activity increases when stable warm temperatures and high humidity trigger reproductive behaviours. Disruptions to environmental conditions often pause breeding entirely, emphasizing the importance of consistency. Creating breeding-conducive environments requires unwavering attention to temperature, humidity, and substrate depth. Adequate calcium availability proves essential—calcium-deficient females often reabsorb developing eggs or produce weak offspring unable to survive. The deep substrate these species require becomes particularly important during breeding, as females seek secure underground locations for releasing their young. Juvenile isopods emerge as perfect miniatures of adults but remain particularly vulnerable during early life stages. They require 8-12 months to reach full size, with growth rates varying based on temperature, nutrition, and overall environmental quality. Their extended development period means breeding programmes require long-term commitment and patience. Successful colonies eventually become self-sustaining, with multiple generations coexisting peacefully. However, reaching this point demands months or even years of dedicated care. Rush attempts to expand populations through over-collection or inadequate environmental conditions typically fail, often resulting in colony collapse. Care Difficulty and Considerations Helios Rubber Ducky Isopods fall firmly into the medium to advanced difficulty category, making them entirely inappropriate for beginners. Their exacting environmental requirements, slow reproduction, and sensitivity to care errors mean they demand experienced keepers familiar with specialist Cubaris husbandry. Success requires commitment to maintaining very high humidity levels and stable warm temperatures—conditions that challenge even experienced keepers in temperate climates. Their extreme burrowing behaviour means rarely seeing your expensive specimens, testing the patience of collectors accustomed to more visible species. The high initial investment combined with slow breeding means losses prove particularly costly. The deep substrate requirements create maintenance challenges. Spot-cleaning becomes nearly impossible without disturbing extensive tunnel systems, whilst complete substrate changes risk catastrophic colony disruption. Most successful keepers adopt long-term substrate management strategies, gradually refreshing portions whilst leaving established areas undisturbed. Their sensitivity to environmental fluctuations means Helios Rubber Ducky Isopods require dedicated, climate-controlled spaces. Casual keeping in rooms experiencing seasonal temperature variations or inconsistent heating typically ends in failure. The specific combination of high heat, extreme humidity, and good ventilation proves technically demanding to maintain consistently.
