The adult moth of this species is pale brown, often with three brown zigzag transverse lines on each forewing, and two on each hindwing. One sex is able to evert a tuft of black hairs from the tip of the abdomen, presumably to disperse pheromones. The wingspan is about 2.5 cms. The underside of the abdomen is white.
