pill bugs

Armadillidiidae is a family of woodlice, a terrestrial crustacean group in the order Isopoda. Unlike members of other woodlouse families, members of this family can roll into a ball, ability they share with the outwardly similar but unrelated pill millipedes and other animals. It is this ability which gives woodlice in this family their common name of pill bugs,[1] doodle bugs, or roly polies. The best-known species in the family is Armadillidium vulgare, the common pill bug.

Family Armadillidiidae (Pillbugs) Mouthparts are for chewing and rasping. Sowbugs and pillbugs spend bright daylight hours in damp dark habitats such as underneath stones, logs, leaf litter and other debris. At night they venture out and feed on decomposing organic material, including mulch and grass clippings. They will feed on the tender foliage, stems and roots of young garden vegetable transplants, seedlings and bedding plants. They also rasp the outer skin of cucumbers lying on the ground in gardens, causing fruit to be deformed and blemished.
