Pill bug (roly-poly, woodlouse)

Moist, sheltered places such as leaf litter, soil, compost, under stones, and decaying wood; commonly found around buildings in damp areas.

Detritivore feeding mainly on decaying leaves, wood, fungi, algae, and other organic debris; occasionally nibbles tender plant tissue.

Mostly nocturnal and moisture-dependent. When threatened, it curls into a tight ball; females carry developing young in a brood pouch.

Harmless to humans and pets and does not bite or sting. It helps decompose organic matter and recycle nutrients, though large numbers may damage seedlings or enter damp buildings.
