pillbug

Armored garden crawler

A pillbug is a small crustacean that lives on land, typically found under rocks, logs, and leaf litter.

Despite appearances, it's not an insect but related to shrimp and crabs.

When disturbed, it curls into a tight ball—hence the name.

Also called a roly-poly or woodlouse.

The kids spent the afternoon collecting pillbugs from under the porch.
