The wingspan is 11–14 mm. The moth flies in June depending on the location.
The larvae feed on birches, elms, alders, hazels, apples, Crataegus, Sorbus, willows, Comptonia peregrina and Quercus wislizenii. They create a strongly curved youth case. The adult case is a tubular leaf case. It is trivalved and about 7 mm in length. The mouth angle is about 30°. It is straw coloured. Larvae start feeding in September and continue to the end of October. They hibernate in their case, and resume feeding in April.
