Blaberidae

Giant cockroaches, or blaberids (family Blaberidae), are the second-largest cockroach family by number of species. Mostly distributed in warmer climates worldwide, this family is based on the American genus Blaberus, but much of the diversity is also found in Africa and Asia.

Description

They are the only ovoviviparous cockroach family. The ootheca is seen very briefly before being retracted into the body, where soon after the young nymphs hatch inside, the female gives live birth. The cerci are smaller compared to other families, and most of the time are covered by wings. They're mostly found in caves, rotting logs or buried under leaf litter. Many are often kept as pets or as feeder insects, such as Blaberus, Gromphadorhina or Macropanesthia.
