Philoscia muscorum, the common striped woodlouse ^[2] or fast woodlouse, ^[3] is a common European woodlouse. It is widespread in Europe, the British Isles and is found from southern Scandinavia to Ukraine and Greece. ^[4] It has also spread to Washington and many states in New England, also the mid-Atlantic states of Pennsylvania and New Jersey, as well as Nova Scotia. ^[4]

Description

P. muscorum may reach 11 millimetres (0.43 in) in length, with a shiny body which is mottled and greyish-brown in colour. ^[3] The fast woodlouse is, as its name suggests, faster than other common species; its body is raised up off the ground rather more than the others and the head is always very dark in colour.
