Broad Wood Cockroach
A distinctive flat, broadly shaped wood cockroach from the southeastern United States. Females have a wider body than most Parcoblatta species.
Did You Know?
Its unusually broad and flat body shape allows it to squeeze into extremely narrow crevices under bark.
Giant Pill Millipede
A large pill millipede that can roll into a perfect sphere the size of a golf ball when threatened. The body is dark brown to black with smooth, overlapping plates.
Did You Know?
When rolled into a ball, the armor plates lock together so tightly that most predators cannot pry them apart.
