There are two generations per year with adults on wing in May and again in August.[3]
The larvae feed on Betula x alpestris, Betula grossa, Betula pendula and Betula pubescens. They mine the leaves of their host plant. They create a small lower surface tentiform mine. The lower epidermis is greenish-yellow and weakly folded. Pupation takes place within the mine in a cocoon. The frass is deposited in a corner of the mine.[4]
