The wingspan is 33–40 mm. The forewings are dull grey-brown to yellow-brown, with a faint antemedian line and slightly more prominent postmedian line. The forewings are slightly paler in the basal and terminal areas. The hindwings are lighter brown, almost white in the basal half. Adults are on wing in mid-summer in one generation per year.

The larvae feed on Helianthus annuus. They burrow into the head of the host plant and feed on the seeds.[2]
