The wingspan is 11–16 mm. The forewings are greyish brown to ochreous brown, mottled with fuscous. The hindwings are pale brown, but darker towards the apex. Adults have been recorded on wing from early April to late September. In the north, there probably is one generation per year. In the south, there are two generations per year.
