Common pill millipede

Moist leaf litter, soil, decaying wood, and sheltered areas beneath logs or debris, mainly in temperate regions.

Feeds primarily on decaying leaves, wood, fungi, and other organic detritus; it does not normally bite or feed on living plants.

Mostly nocturnal and slow-moving, with many overlapping body plates. When disturbed, it curls into a tight ball; eggs and juveniles develop in moist soil or litter.

Harmless to people, pets, and buildings, with no venom or significant bite risk. It helps decompose organic matter and recycle nutrients, though large numbers indicate damp, debris-rich conditions.
