What Ubiquitous Insects Are Actually Crustaceans?

Answer: Pillbugs

Among the wide variety of things that creep and crawl across the Earth, there is a very small and peculiar overlap between the oceans and the land. Armadillidiidae, most commonly known in the United States as a Pillbug and less commonly as a Roly Poly, Chiggy-Wig, and Potato Bug, certainly looks like a tiny little insect, but is in fact a distant relative of distinctly aquatic creatures like shrimp and crabs. The prolific little bug is actually not a bug at all, but one of the rare crustaceans found outside of water.
