Oviposition usually near the leaf tip. Oviposition scar mostly an elongated lacerated hole. Very long corridor (up to 10 cm), upper-surface, strongly widening towards the end. Primary and secondary feeding lines apparent in fresh mines. Pupation outside the mine, exit slit in upper epidermis. Often several mines in a leaf. Mines invariably in leaves that are not yet fully developed, and are strongly malformed as a result.
Larvae in May – October (Hering, 1957a, Nowakowski, 1960a); hibernation as puparium.
Not known from the Benelux countries (Fauna Europaea, 2008).
