Background Pillbugs, roly-polys, and potato bugs are the dominant common names for the isopod genus Armadillidium spp. As the scientific name suggests, these little critters resemble mini armadillos but are, in fact, crustaceans that live on land (Figure 1). Therefore, they are more closely related to lobsters, crabs, and shrimp than insects. Pillbugs are important[Read More…]
