Scientific name: porcellio scaber
The woodlouse (also called an armadillo bug, carpenter, cheeselog, doodlebug, pill bug, roly-poly, chuggypig, slater beetle, sow bug or gramersow) is a type of crustacean, and is related to the crab and lobster. They eat dead plants and fallen leaves. Woodlice breathe through gills like fish, which is why you often find them in damp places. Some types of woodlouse can roll themselves up into a tight ball.
