The wingspan is 10–13 millimetres (0.39–0.51 in). There are multiple generations per year, with adults on wing between April and November.[3]
The larvae feed on Fagus sylvatica and Quercus robur. They mine the leaves of their host plant. The mine starts as a narrow lower-surface epidermal gallery, regularly intersecting itself. Later, the mine becomes full depth. It remains a small mine, either rectangular or (more frequently) a triangle in a vein axle, with frass along the sides. Older larvae leave the mine and continue feeding in a leaf roll. Pupation takes place in a white cocoon.[4]
