Common striped woodlouse, Fast woodlouse
Philoscia muscorum, the common striped woodlouse or fast woodlouse, is a common European woodlouse. It is widespread in Europe, the British Isles and is found from southern Scandinavia to the Ukraine and Greece. 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.
P. muscorum may reach 11 millimetres (0.43 in) in length, with a shiny body which is mottled and greyish-brown in colour. 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.
