Woodlouse (specifically Common Woodlouse)

Moist, dark environments such as under rocks, logs, leaf litter, and occasionally damp indoor basements.

Detritivore; eats decaying organic matter, fungi, and rotting vegetation.

Nocturnal; they require moisture to breathe through gill-like structures and will congregate in damp areas to avoid dehydration.

Harmless to humans; they benefit the ecosystem by breaking down organic matter and recycling nutrients back into the soil.
