The adult moths of this species have a brownish-grey pattern, with a white subterminal line on each wing, and a large dark spot on the hind margin of each forewing. The hind margin of the forewing is concave. Like many in this subfamily (EPIPLEMINAE): the moth often exhibits an interesting resting posture. This one sometimes creases its wings, and sometimes has its the hindwings above its forewings.
