Larva

The wingspan is 9–10 mm. Adults are on wing in May and again in August in two generations.[2]

The larvae feed on Corylus avellana, Corylus colurna and Corylus maxima. They mine the leaves of their host plant. The mine consists of a small, rectangular mine between two side veins. The larva starts feeding in the spongy parenchyma. Later also the palissade parenchyma along the outline of the mine is consumed. In the end, all palissade parechyma is eaten away and the mine has become full depth. Most frass is deposited in a corner of the mine. After leaving the mine the larva lives in a folded leaf margin.[3]
