The adult moths have transparent wings with broad dark brown borders. There is a tuft of brown hairs on the tip of the abdomen. The tuft on the end of the abdomen of the female is rather bushier than that of the male. Unfertilised females are quite amusing as they are inclined to keep wiggling this tuft in a figure of eight, presumably to better disperse a pheromone which they emit, in order to attract a male.
