The roly-poly bug, also known as the pill bug or armadillidiidae, is a small, terrestrial crustacean that can be found in gardens and damp environments. Unlike insects, these creatures have a hard, segmented exoskeleton and seven pairs of legs. They are known for their ability to roll into a ball when threatened, which provides protection from predators. Roly-poly bugs primarily feed on decaying plant material, playing an important role in the ecosystem by helping to break down organic matter. They are most active at night and prefer moist habitats, making them common in leaf litter and under rocks.
