This is one of the largest native woodlice in the British Isles. It is fairly flat and shiny, marbled greyish-brown in colour with pale markings. Yellow or orange forms may occur. Length 14mm.
After dark they forage for dead organic matter.
Seen all year round. Found in a wide variety of habitats, including woodland, hedgerows, waste ground, and quite numerous in gardens. They easily dry out, so they shelter under rocks or stones, rotting logs or plant detritus. Common and widespread throughout.
