Discoid Roach
Blaberus discoidalis
The discoid roach, Blaberus discoidalis, is a large tropical cockroach widely kept as a feeder insect for reptiles, amphibians, tarantulas, and some birds. It has a flattened oval body, tan to brown wing covers, and nymphs that hide readily in bark or egg-crate stacks. Adults have wings but are not strong fliers, and the species is often chosen by keepers who want a productive roach colony with less climbing ability than many pest cockroaches.
Colonies are usually maintained in warm, dark, well-ventilated bins with vertical cardboard, dry grain-based feed, vegetables, and a safe moisture source. Discoid roaches give birth to live young rather than laying exposed egg cases, so a stable breeding colony can grow quickly when heat and food are consistent. Feeders are often gut-loaded before use to improve their nutritional value. Escapes, allergies, and local regulations still deserve attention, and unwanted roaches should never be released outdoors.
