When I flipped over this earthstar which had blown away from its site, I saw this sowbug and realized I had no photos of this common creature. Sowbugs (perhaps more familiarly known as woodlice)are actually in the Class Crustacea, along with crayfish and shrimp, so remember that next time you see one of these common little creatures! Sowbugs are Isopods in the Family Oniscidae. They scavenge dead plant material and fecal matter in the soil according to a fascinating article by Louise Kulzer.
