The wingspan is 16–20 mm. Adults are on wing in June and July. It often needs two years for development.
The larvae feed on Corylus, Juglans, Castanea, Fagus and Quercus species. The larvae usually only feed inside nuts that have fallen to the ground, but at times the larvae cause significant damage by causing the nuts to drop.
