Leaf-mine: Broad corridor, starting not far from the base of the blade, running upwards. Frass deliquescent, only few grains recognisable, mine greenish. Larva solitary. Pupation outside the mine (Bladmineerders van Europa).

Larva: The larva is described by Darvas and Papp (1985) and Darvas, Skuhravá and Andersen (2000). Mandibles each with 2 heavy teeth, front spiraculum with 11-14, rear spiraculum with 3 bulbs. The bulbs of the rear spiracula are elongated and S-shaped (d'Aguilar, Chambon and Touber, 1976a; Hering, 1957a, 1962a; Spencer, 1973b) (Bladmineerders van Europa).

Puparium: Entirely reddish-brown; posterior spiracles each with 3 bulbs (Spencer, 1976: 115).

Uniformly reddish brown, rear spiracula on low protuberances, separated by their own diameter (d'Aguilar, Chambon and Touber, 1976a; Hering, 1957a, 1962a; Spencer, 1973b) (Bladmineerders van Europa).
