The wings of the adult moths of this species vary in colour from grey to rusty brown. The wings each have incomplete angular dark lines dividing the basal, central, and marginal thirds, each of which shade continuously. The forewings each have a pale patch extending from middle of the hind margin. The male has a dark angular spot near the middle of each wing. The margin of each hindwing has a large triangular bulge with sinuous edges. The wingspan is about 3 cms.
The moths rest the wings held flat. Sometimes the forewings are held separate from the hindwings, but with a crease in each forewing. The creases partly obscure the central dark spots on the forewings. Sometimes the moths rest with the forewings overlapping the hindwings so that their patterns align, and with no creases in the forewings.
The undersides are similar to the upper surfaces, with more exaggerated colours and patterns, sometimes with the addition of a submarginal sinuous white lines.
