Armadillidium sordidum (Sordid Pill Woodlouse)

Native to southern France, Corsica and parts of Italy, Armadillidium sordidum is a beautifully patterned European isopod with warm, autumnal-brown colouring and intricate golden marbling. Its markings resemble patches of lichen scattered across its body, giving it excellent natural camouflage.

One of the loveliest things about this species is how much the pattern varies between individuals. Some have delicate golden flecks, while others display larger, irregular patches across their segments, meaning no two look quite the same.

Hardy, active and prolific, Armadillidium sordidum is a lovely choice for keepers who enjoy colourful, naturally patterned isopods and want a colony that is rewarding to watch grow.

Care Information

• Size: Mixed sizes.
• Diet: Rotting hardwood, leaf litter (oak, beech, maple, chestnut, Asian species), and lichen form the staple diet. Supplement regularly with calcium (cuttlefish bone, limestone, or powdered calcium carbonate), protein-rich treats (fish flakes, shrimp pellets) and vegetables (squash, carrot, zucchini, or sweet potato).
• Temperature: 20–24 °C. Room temperature is usually fine
• Humidity: 40–60%. Maintain a moist/dry gradient: one side humid with moss or damp substrate, the other drier. Mist lightly or use a dropper every week to maintain stability without waterlogging.
• Ventilation: Provide good cross-ventilation to prevent stagnation, while keeping humidity stable.
• Substrate: Substrate minimum ~5cm deep mix, organic soil, flake soil, rotting wood, sphagnum moss, and leaf litter. Add cork bark and hardwood pieces for shelter.
• Enclosure: 3L Braplast tub or larger. For growing colonies 5L and 11L tubs may be more suitable.

Isopods are shipped securely in ventilated tubs with damp moss for safe travel.
