The wingspan is 6–8 mm. There are two generations per year with adults on wing in May and again from July to August.[2]
The larvae feed on Carpinus betulus and Ostrya carpinifolia. They mine the leaves of their host plant. They create a narrow, finally tubular lower-surface mine between two side veins. The lower epidermis has one strong fold. The pupa is made in a flimsy cocoon in a corner of the mine. The frass is deposited in the opposite corner. In Ostrya, the mine is shorter and less constrained by the lateral veins.[3]
