The habitat consists of sage steppes.

The length of the forewings is 12-14 mm. The forewings are light orange-brown and grey, marked with a pale-filled oval orbicular spot and grey-filled reniform spot. The hindwings are warm tan, slightly darker towards the margin. Adults are on wing from mid-April to mid-September.
