The wingspan is 7–8 mm and the moths are on wing in May and August in two generations.
The larvae feed on Corylus avellana and Corylus colurna mining the leaves of the host plant creating a lower-surface tentiform mine, usually between two side veins. The pupa is formed in a white cocoon in a corner of the mine. It is attached to both the roof and the floor of the mine. The frass is deposited in an opposite corner.
