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.
Behaviour
