Woodlouse

Damp, dark places such as under rocks, logs, leaf litter, and occasionally in basements or bathrooms.

Mostly detritivores, eating decaying plant matter, fungi, and sometimes animal remains.

Nocturnal and moisture-seeking. They often congregate in large numbers to conserve moisture. Some species can roll into a ball (pill bugs) when threatened.

They are harmless to humans and do not bite or sting. Benefit ecosystems by recycling nutrients through the decomposition of organic matter.
