Giant Cockroaches, Blaberids
Blaberidae is the second-largest family of cockroaches with over 1,260 species in 170 genera and 14 subfamilies. Members are distinguished as the only ovoviviparous cockroach family, where females retract the ootheca into the body and give birth to live nymphs. The family exhibits exceptional diversity in form and behavior, including burrowing species, conglobulating (ball-rolling) pill roaches, and hissing cockroaches. Many species are kept as pets or feeder insects.
