A fairly common species in Belgium. 

The yellowish larva makes a leafmine on Betula. Egg is usually laid on the underside of the leaf, close to a vein. The mine starts as a narrow not strongly contorted gallery, not discolouring the leaf tissue and the brown or black coiled frass lying in arches, leaving very narrow clear margins. Often the mine starts near the leaf margin and after the usually early whirls progresses in a straight line beside a rib. Pupation in a pale buff cocoon among leaf litter.

The adults fly probably in two generations a year or perhaps in a single protracted generation.
