Pill bugs are land-dwelling crustaceans that breathe through gills like their water-dwelling cousins. They must stay moist, so I often find them underneath boxes and buckets. One study found as many as 10,000 individuals living in a square meter. Originating in Europe, these roly polies are naturalized in North America and are an important part of the soil ecosystem - breaking down woody plant material so we don't live amongst every fallen tree that ever was. #rolypolies #pillbugs #armadillidiumvulgare #beneficialbugs #leichtlunch (at Delaware County, Pennsylvania)
