Blaberus atropos
A large Blaberus cockroach from the Neotropics. Like its relatives such as the death's head roach, it keeps the ootheca inside its abdomen until the nymphs hatch.
Blaberus atropos (Stoll, 1813) is a cockroach of the family Blaberidae described in 1813. The Catalogue of Life gives records from Guyana and Trinidad and Tobago, and GBIF also holds observations from Brazil, Colombia and elsewhere in Central and South America. Blaberus is a Neotropical genus of large cockroaches with more than 30 valid species, several of which, such as B. discoidalis, are widely kept by hobbyists for display or as feeders. Members of the genus keep the ootheca inside the abdomen rather than dropping it, and give birth to live nymphs. Little has been published on the size or life history of this species in particular, and it resembles B. craniifer, B. discoidalis and B. giganteus, so check the scientific name and origin when buying. In Japan it is occasionally sold by specialist shops alongside other members of the genus.
