Armadillidium pictum is a species of woodlouse which occurs over most of Europe, except the Mediterranean Basin and Southeast Europe. [3] In the British Isles, it is only known from a few sites, making it by some accounts, "Britain's rarest woodlouse". [4] Since these sites are all remote from human habitation, in Cumbria and Powys, the species is thought to be native rather than introduced. [5]
Armadillidium pictum is chiefly a forest species, and may be found several metres above the ground under loose bark or in holes in rotting wood. [6] It closely resembles A. pulchellum , but it is darker in colour, with less distinct mottling, which is arranged in lines along the length of the body. It is also, at up to 9 mm (0.35 in) long, slightly larger than A. pulchellum. [5]
