They exhibit sexual dimorphism, with adult males having full wings that cover the entire body, while females have only small wing stubs. Adults range in color from dark brown to black, with a slightly lighter orange striped pattern sometimes visible only in bright light. Coloration differs slightly with environment and diet from one colony to another.



Dubia roaches spend 75% of their time in cracks. Their preferred locations are those that are the right size for their body and that are located near water and food sources, warm and with a high relative humidity. They are most active during the night.



This species can be considered a pest. It is widely traded to be used as live food for other animals such as tarantulas, amphibians, or reptiles. Canada and the United States of America have banned the commercialization of this animal because it is considered an invasive species in both countries.
