A very rare species in Belgium, which seems not capable of surviving normal winters.
Young larvae mine young leaves or soft shoots, older larvae feed freely between fresh spun shoots and leaves. Pupation in a cocoon on leaves, branches or trunks. Overwinters as a small larva in the mine. Seems uncapable of surviving normal winters in Belgium, but imported larvae can complete their development and can produce multiple generations during summer and autumn.
