Armadillidium vulgare

Also commonly reffered to as the Common Pillbug, Sowbugs (even though this is an incorrect classification), Roly-Polies and even Wood Lice. They are members of the Isopods, not to be confused with an insect[1]. They belong to the family Armadillidiidae and are found almost everywhere and are soil/ground dwelling isopods.
