A woodlouse is basically a tiny, armored bug that looks like a cross between a shrimp and a roly-poly. It scuttles around on many little legs, often pretending to be a bug version of a pill, rolling into a ball when it feels threatened. They hang out in damp places like under rocks or in the dirt, probably plotting their next snack of decaying leaves. They don't really fly, and they definitely don't sing or dance, but they sure know how to make a home in your garden mulch!
