Armadillidium pallasii 'Orange' (Corfu) Isopods for Sale

Armadillidium pallasii 'Orange' is one of the most genuinely beautiful Armadillidium morphs in the UK hobby — a vibrant, semi-translucent orange selectively-bred variant of the large Greek pill woodlouse from Corfu. Their bodies glow in a warm, almost luminous orange tone that catches the light beautifully, and combined with the impressive size of the species (one of the largest Armadillidium available), they make a properly striking display isopod. The orange colouration is a form of hypomelanism — a selectively-bred reduction in dark pigmentation — and the Pallasii Orange is considered by many keepers to be among the brightest orange Armadillidium morphs in the hobby today.

The species itself, A. pallasii, is also known as Pallas's Pill Woodlouse — its scientific name honours Peter Simon Pallas, the celebrated 18th-century German zoologist and botanist (pronounced palace-sea-eye). You may also find this species traded under older or alternative names: Armadillidium frontirostre, Armadillidium frontesignum, A. cf. frontirostre, or as the popular common name "Croatian Giants". Whatever the name, the animal is the same — and a colony's worth of them is a genuinely lovely sight.

They sit alongside the standard A. pallasii (same species, wild grey-brown colour) as a clean two-morph pairing, and within the broader Greek/Corfu Armadillidium cluster alongside the metallic A. corcyraeum 'Silver' — both pallasii morphs and corcyraeum being Corfu natives. Like all Armadillidium, they conglobate (roll into a tight defensive ball) when disturbed, and combined with that bright orange they're among the widest-rolling isopods in the hobby.

What Makes Pallasii Orange Isopods Special

Several factors make the Pallasii Orange a genuinely beautiful Armadillidium:

The vibrant, semi-translucent orange body. This is the headline. The colouration is brighter and warmer than most orange isopods — almost luminous in the right light, with a subtle translucent quality that catches light beautifully. It's a real visual standout, and considered by many keepers to be the brightest orange Armadillidium morph available.

Impressive size. A. pallasii is one of the largest Armadillidium species in the hobby — adults reach up to 24 mm, larger than most popular Armadillidium and comfortably exceeding species like Zebra (~18 mm) or Magic Potion vulgare (~15 mm). Combined with the bright colour, they're a properly substantial display species.

Lovely scientific heritage. The species epithet pallasii honours Peter Simon Pallas, the celebrated 18th-century zoologist, geologist and botanist (pronounced palace-sea-eye). For keepers who appreciate the natural-history side of their hobby, it's a quiet but memorable detail.

Year-round prolific breeders. Once established, they breed continuously throughout the year — building substantial colonies quickly under good conditions, which makes them dependable cleanup crew for bioactive setups as well as a display species.

One of the widest-rolling isopods. When disturbed, they conglobate into particularly wide, full balls — a satisfying behavioural feature on a large isopod.

A natural Corfu Armadillidium cluster. Both pallasii morphs (standard and Orange) and the metallic A. corcyraeum 'Silver' are native to Corfu, making them a coherent collector's set built around a single Greek island.

Calm temperament. They're notably calm and tolerate group housing well — peaceful as colonies grow, and visible at night and early morning rather than perpetually hidden.

How Pallasii Orange Compares to Other Large and Orange Armadillidium

If you're choosing between large or warm-toned Armadillidium, here's how the Pallasii Orange fits in:

• vs Standard Armadillidium pallasii: Same species, different look — the standard shows wild-type grey-brown colouration; the Orange is the selectively-bred hypomelanism morph. Identical care, identical size — choose by preference, or keep both as a clean morph pair.
• vs A. corcyraeum 'Silver': Both are Corfu natives, both true Mediterranean Armadillidium. Corcyraeum 'Silver' is the smaller metallic-silver morph; Pallasii Orange is the larger vibrant orange. Natural Corfu companions — different colours, same Greek island.
• vs A. vulgare T+ Albino: Both are warm-toned Armadillidium morphs. The T+ Albino is a smaller orange-gold vulgare; Pallasii Orange is the larger, brighter Greek species. Different species, complementary in a warm-Armadillidium collection.
• vs Magic Potion (A. vulgare): Magic Potion is the small pale-toned vulgare morph; Pallasii Orange is the much larger, vivid Greek species. Different scales and intensities.

Setting Up the Enclosure

Because these are larger Armadillidium with a prolific breeding rate, give them room — a 10–15 litre plastic container or terrarium suits a starter colony, with larger housing as the population grows. Plastic tubs with clip-lock lids hold appropriate humidity while allowing the ventilation Armadillidium need. The 3L Braplast tub works only for small starter groups; this species genuinely benefits from more space.

Provide plenty of hides — cork bark, leaf litter, decaying wood, and bark pieces — for cover and surface activity. The vibrant orange colouration shows particularly beautifully against darker, naturalistic substrate. Keep the enclosure dim and out of direct sunlight, as they're more active at night and early morning. Browse our accessories collection for appropriate enclosures, vents, and other essentials.

Substrate

Build a Mediterranean-style substrate appropriate for this hardy Greek species:

• Organic topsoil base (pesticide-free) as the foundation
• Sphagnum peat moss mixed throughout for moisture retention in moderation
• Flake soil mixed in for added nutrition
• Crushed limestone or eggshells distributed throughout for calcium — important for the large adults' moulting
• Decaying hardwood pieces and rotting wood incorporated throughout
• A little forest moss for humidity and grazing

We recommend a topsoil and sphagnum-based mix rather than coco coir. Substrate depth: 5–8 cm for burrowing and security.

Top layer: Generous hardwood leaf litter — magnolia leaves and oak leaves work particularly well for long-lasting cover and food. Add cork bark and decaying wood for hides, plus a sphagnum moss patch concentrated in roughly one-third of the enclosure to create the moist zone of the gradient.

Humidity and Temperature

Maintain moderate humidity (around 60–75%) with a clear moisture gradient. Keep roughly one-third of the enclosure moist with sphagnum moss and damp leaf litter, while the rest stays drier with leaf litter and bark cover. Critically, both extremes — too humid OR too dry — cause moulting problems in this species; the balance matters more than absolute precision.

Avoid spraying the isopods directly; mist the moist side of the enclosure as needed to maintain the gradient. As one PostPods customer noted about following the website's care guidance for Mediterranean isopods, getting moisture right is the key to keeping them successfully — too much moisture is a common mistake, but uniform dryness causes moulting failures too. A modest springtail culture in the moist corner helps manage mould.

Temperature should be 20–28°C — they're warmth-tolerant Mediterranean isopods comfortable across a wide range (15–28°C overall acceptable). UK room temperature suits them year-round in most heated homes.

Diet

Pallasii Orange isopods are detritivores with broad, slightly protein-leaning appetites:

• Primary diet (always available): Hardwood leaf litter (oak, beech), decaying rotting wood, dried plant matter
• Vegetables (1–2x weekly): Carrot, courgette, sweet potato, squash, leafy greens. Replace within 24–48 hours.
• Fruit (occasionally): Small amounts of soft fruit
• Protein (1–2x weekly — slightly more than most species): Fish flakes, freeze-dried shrimp, dried daphnia. They benefit from a slightly higher protein intake than many other Armadillidium. Browse our accessories collection for the full range of protein supplements.
• Calcium (essential — always available): Cuttlefish bone, crushed limestone, oyster shell, eggshells. Especially important for this large-bodied, prolific species — provide multiple sources distributed throughout.

Feeding approach: Maintain a base of leaf litter and decaying wood, supplementing with vegetables, occasional fruit, regular protein (slightly more than most species), and a constant calcium source. Remove uneaten fresh foods within 24–48 hours to prevent mould.

Breeding

Pallasii Orange isopods are very prolific year-round breeders once established — building substantial colonies quickly under stable conditions.

Breeding basics:

• Females carry developing young in a marsupium and release fully-formed live juveniles
• Breeding continues throughout the year, not just seasonally
• The vibrant orange colouration develops as juveniles mature through successive moults
• A pure Orange colony breeds the morph reliably

For breeding success:

• Stable temperatures within range (22–25°C is ideal)
• A proper moisture gradient (60–75% humidity with one-third moist)
• Abundant calcium for the large breeding females
• Regular protein supplementation (more than most species)
• Plenty of cork bark and leaf-litter hides
• A larger starter group — see the establishment note below

One honest note worth setting expectations on: the Orange morph has been observed to have a slightly higher mortality rate than the wild-type during initial establishment. Starting with a larger group (rather than the absolute minimum) and giving them time to settle into stable conditions helps ensure the colony establishes successfully. Once they're settled, they're as prolific as any wild-type pallasii.

Pair With Springtails

Add a thriving springtail culture to any Pallasii Orange setup. Springtails handle mould and microbial growth at a scale isopods can't manage — particularly useful around protein foods (this species takes more than most) and in the moist zone of the moisture gradient. They coexist peacefully with the Pallasii Orange and form a helpful cleanup partnership.

Who Should Buy Pallasii Orange Isopods?

Ideal for:

• Keepers wanting a bright, vibrant orange display Armadillidium
• Those drawn to large, substantial isopods (these are among the biggest)
• Collectors building a Greek/Corfu Armadillidium cluster (standard + Orange Pallasii + Corcyraeum Silver)
• Bioactive setup builders wanting an attractive, prolific year-round breeder
• Anyone interested in semi-translucent isopod colour morphs
• Reptile/amphibian keepers wanting large soft-bodied isopods that double as occasional feeders

Not ideal for:

• Heavily-planted bioactive setups where plant-nibbling is a concern
• Tiny enclosures that won't accommodate large adults or fast colony growth
• Setups prone to humidity extremes in either direction (both too wet and too dry cause moulting problems)
• Keepers wanting absolute beginner-easiest stock — start with a larger group to manage initial mortality

Realistic Expectations

The orange is the genuine selling point. Set expectations toward the vivid, semi-translucent orange colouration — that bright glow is what makes them stand out, and it deepens with maturity through successive moults.

They're properly large. Don't underestimate the size — at up to 24mm they're substantially bigger than most popular Armadillidium. Plan enclosure space accordingly, especially given how prolific they are once established.

Humidity balance matters more than extremes. Both too wet and too dry cause moulting problems with this species — aim for the moderate-with-gradient sweet spot and avoid pushing in either direction.

The Orange morph has slightly higher establishment mortality. As a selectively-bred hypomelanistic morph, the Orange line shows somewhat higher early-stage mortality than the wild-type. Starting with a larger group helps the colony establish reliably.

They eat more protein than most. Worth knowing for feeding planning — they benefit from slightly more frequent protein supplementation than the average Armadillidium.

Building Your Setup

A complete Pallasii Orange setup needs a roomy enclosure, basic substrate components, abundant calcium-rich materials (essential for the large breeders), generous leaf litter and bark, and regular protein supplements. Browse our accessories collection for everything you need — enclosures, ventilation, leaf litter, calcium (cuttlebone, limestone, oyster shell), and protein supplements.
