The nymph looks similar to the adult counterpart, but wingless, orange-brown, and with black and spindly legs. It undergoes 5 development changes for about 3 weeks.

The adult is dark-brown or black in color with red thorax, white and black abdomen, brownish-yellow legs, and greenish-brown wings. It is very active early in the morning or late afternoon. The female could lay up to 50 eggs. Life span could last for several weeks.
