The pillbug, also known as roly-poly or armadillidiidae, is a small, terrestrial crustacean that can be found in gardens and damp environments. Unlike insects, pillbugs have a hard exoskeleton and seven pairs of legs. They are known for their ability to roll into a ball when threatened, which provides protection from predators. Pillbugs primarily feed on decaying plant material, playing a vital role in the ecosystem by aiding in decomposition. They are often mistaken for insects, but they are more closely related to crabs and lobsters. These creatures are most active at night and prefer moist habitats to prevent dehydration.
