woodlouse

Roly-poly bug

A woodlouse is a small crustacean with a segmented, armor-like body, found in damp environments under logs, stones, and leaf litter.

Despite the name, woodlice are not insects but relatives of crabs and lobsters adapted to land.

Some species curl into a ball when disturbed, earning names like pill bug or roly-poly.

Plural: woodlice.
