Porcellio dilatatus
A woodlouse native to south-western Europe and now established around buildings worldwide. The broad oval body is grey to dark brown and it burrows readily. Hardy and drought tolerant, it is a widely used beginner cleanup species.
Porcellio dilatatus, described by Brandt in 1831, is native to south-western Europe and has spread with human traffic to North and South America, Australia and beyond, where it lives around buildings, greenhouses and flower pots; five subspecies are recognised. Adults are about 15-20mm with a broad oval body of grey to dark brown, the central lobe of the head always darker, and a tongue-shaped rounded telson that separates it from similar species. It burrows and eats the substrate itself, so provide a depth of at least 5-10cm. Leaf litter and rotten wood are the staples, supplemented with vegetables, fruit, protein and calcium. It is nocturnal and also active in the early morning. Drought tolerant and forgiving of fluctuations, it is widely used as a vivarium cleanup crew. Breeding is reliable, with moderate colony growth.

Leaf litter, rotten wood and substrate humus as staples, with vegetables, fruit, protein and a calcium source.
15-26C and 50-70% humidity. Keep one third moist and the rest dry; fairly drought tolerant.
It burrows and eats substrate, so lay leaf humus at least 5-10cm deep topped with moss, rotten wood and leaves.
Keep leaf litter and rotten wood available; add vegetables, fruit, protein and calcium.
Harmless. Nocturnal and active at dawn, burrowing by day. Keep in groups.
Established around buildings worldwide, so never release outdoors. Burrowing makes head counts difficult.
Beginner. This is a beginner-friendly species. No special equipment or experience is required, and it can be kept successfully with basic care setup.
