Cylisticus convexus
A woodlouse native to Europe and now established worldwide. It rolls up, but the antennae and long uropods stick out of the incomplete ball. Colour ranges from grey to wine-red; hardy, fast-breeding and popular as a cleanup crew.
Cylisticus convexus, described by De Geer in 1778, is a woodlouse of the family Cylisticidae native from Europe to the Caucasus and introduced to North and South America and North Africa. It is often found around buildings and is called the 'urban woodlouse' in German. Adults are about 10-15mm, with colour ranging from slate grey and grey-brown to wine-red, and pale dashes along either side of the back. It can roll up, but the antennae and long pointed uropods protrude from the incomplete ball, which separates it from Armadillidium; it also has five pairs of pleopodal lungs. Leaf litter and rotten wood are the staples, and protein from isopod food or fish flakes boosts breeding. It is very active and prolific, and a pied line from Ukraine is traded as 'Ukraine Pied'.

Leaf litter and rotten wood as staples, with isopod food, fish flakes, vegetables and fruit for protein and plant matter.
15-28C and 50-65% humidity. A moist-to-dry gradient makes it tolerant of fluctuations.
A ventilated container with soil, sphagnum and leaf litter, plus cork and bark; it also climbs vertical structures.
Keep leaf litter and rotten wood available; add isopod food, fish flakes, vegetables and fruit. Extra protein speeds breeding and growth.
Harmless and very active. Nocturnal but often seen on the surface. Keep in groups.
Breeds very quickly and can overpopulate; manage numbers when used in a vivarium.
Beginner. This is a beginner-friendly species. No special equipment or experience is required, and it can be kept successfully with basic care setup.
