Pillbugs / Sowbugs
Pillbugs can roll into a ball, an ability they share with the outwardly similar but unrelated pill millipedes and other animals, or roly polies. This ability may be triggered by stimuli such as vibrations or pressure, and is a key defense against predation; it may also reduce respiratory water losses. Pillbugs can be considered pests of homes and gardens.
• Adult pillbugs grow to about 3/8 inch long and have a number of rounded body segments with seven pairs of legs.
• Pillbugs can live up to three years.
• Females lay eggs that they carry in a pouch underneath the body, and hatchlings remain in that pouch for up to two months.
