Armadillidium nasatum

Armadillidium nasatum is a species of terrestrial crustacean belonging to the order Isopoda. These creatures are commonly known as pill bugs or woodlice. A distinctive characteristic of Armadillidium species, including A. nasatum, is their ability to roll into a tight ball when disturbed, resembling a miniature armadillo.123

Originally from northern Europe, A. nasatum has been introduced to North America. Pill bugs, like other isopods, have an elongated, somewhat arched body covered by segmented, armor-like plates. They are often found in damp environments such as leaf litter and the edges of wooded areas.12
