    The adult moths have mottled pale green or grey wings, with two dark zig-zag lines across each forewing, and one across each hindwing. The moths rest with the forewings linked to the hindwings, as they would be in flight, unlike the moths of other species in the genus Pingasa, which unlink the wings and hold the forewings over the head when at rest.
