Leaf-mine: A linear mine running towards the apex of the leaf and this can widen and become almost blotch-like. Pupation internal (Spencer, 1976: 194, 195 (fig. 340).

Upper surface corridor, mostly in the lower half of the blade, running upwards, and never occuping more than half the width of the leaf. Larva solitary. Frass in green smears. Pupation inside the mine (Bladmineerders van Europa).

Larva: The larva is described by Nowakowski (1973) and Venturi (1935). The two rear arms of the cephalic skeleton dark form most of their length. Posterior spiracles laterally with a black, finely spinulose wart, wich is not so large that it covers the tracheal tube behind it (Bladmineerders van Europa).

Puparium: Brownish-black (Spencer, 1976: 194). Illustrated in Bladmineerders van Europa.
