Oniscus asellus

This beastie shown above is one of the largest and commonest species in this country, and it is abundant in gardens and houses all over the British Isles. It reaches lengths of about 16 mm and it can be as wide as 6 mm. It is somewhat flatter than our other large woodlice, and it's body is usually brownish black, with paler mottling and very pale edges to the segmental plates. It is usually rather shiny. The species can also be identified by the long pointed telson. Oniscus asellus is particularly fond of rotting wood and it is usually the commonest species under logs and stones in the garden. It is also likely to be found in houses which have damp porches, outhouses, back kitchens etc.
