Pill bugs, also known as roly polies, are small invertebrates most known for rolling into a ball when threatened. They are wingless, with blue-gray ovular bodies about 0.5 inches long. Pill bugs have seven pairs of legs.

Fast Facts:

  • Despite their names, pill bugs aren't insects. Instead, they are crustaceans, the only crustaceans that can spend their entire lives on land.

  • While they can't live submerged in water, pill bugs need moisture to survive. They are unable to inhabit dry habitats.

  • Pill bugs are decomposers that play the important ecosystem role of decomposing the materials of dead plants and animals.

  • Female pill bugs can carry up to 50 eggs at once. Mothers carry their eggs in a pouch.
