The adults fly in three generations a year: June, August and from October till April. They are mainly active at dusk but occasionally come to light.
The young larva makes a long, sinuous leaf-mine mainly on rosaceous trees or bushes like Prunus cerasus, or on Betula. It pupates in a silken cocoon which is suspended by silken threads on either surface of a leaf. The imago hibernates, often in thatch or evergreens.
