Blaberus parabolicus


Class: Insecta. Order: Blattoptera. Genus:  Blaberus. Species:  Blaberus parabolicus.


Generally found in South America.

Outward appearance

Length: 5 cm. Width: 2.5 cm.  


Will eat an average amount compared to other similarly sized cockroaches. You should always keep a protein supply (dog food works well) and a moisture supply (oranges, water gel, water) at hand in their enclosures. Remove food immediately once it starts to mold or rot.

Maintenance care

Plastic Rubbermaid style bin with a window cut out (glue in window screen).  If you want to show these wonderful animals off, a glass tank 10-20 gallons in size that has a built-in screen lid. Eggflats are ideal for productivity with this species as the enclosure is not very humid and do not mold quickly. I recommend the use of corkbark regardless because it doesn't get soggy or mold and makes for great decoration. These animals prefer it hot and lightly humid, 75ºF-90ºF and 65%+ humidity. Regardless they still do well at room level humidity with moderate weekly mistings. Substrate is not needed with this species if enough hides are provided. But, I always recommend substrate for moisture control and odor reduction. In a show tank a substrate is a must. What natural setting doesn't have dirt or leaves? You can include fake plants as well but be aware that roaches will eat live plants and they could be toxic to them.  A food dish. Keeping food in a dish helps to reduce mold and you can avoid misting the food by simply pulling out the bowl when you do so.   A water dish, remember roaches need moisture in either their diet or as a straight water source. You can use water gel or a shallow bowl filled with water and pebbles to keep the roaches from drowning.


Keep your feeder roaches at a minimum temperature of 68 degrees. If you want them to breed, keep them warm. Day temperatures between 85 to 95 degrees are preferable. Humidity levels should be mid range. Unless you live in a very dry area of the country, there will be enough humidity at 90 degrees. Roaches usually take awhile to start breeding once they reach adulthood, but once they do, Discoid Roaches are steady and reliable breeders. If your adult Roaches are not producing young, then you are keeping the temperature too low. If your roaches die during incomplete molts, then the humidity is too low.

Difficulty keeping
