Forewing purplish fuscous with many fine dark strigulae; the lines finely dark but indistinct, inwardly oblique; the inner line below middle finely golden, the outer golden at inner margin only; median area below middle ferruginous brown, containing at base of vein 2 a large irregular somewhat sinuous shining golden blotch (the golden blotch varies from a subquadrate, somewhat anvil-shaped mark to an elongate, sinuous, tongue-shaped one); a deeper diffuse shade from apex to middle; hindwing dull bronzy yellowish tinged with fuscous; the terminal area diffusely deep fuscous.

Larva pale green; dorsal and spiracular lines white; head pale green marked with brown.

The moth flies from July to August depending on the location, and migrates long distances.
