Leaf-mine: An initially linear leaf-mine, normally adjoining leaf-margin and running towards apex of leaf, then turning and widening into a blotch in the area of the mid-rib (Spencer, 1972: 40, fig. 123; Spencer, 1976: 117, fig. 190).

Hooklike, upper-surface corridor. The corridor begins near the base of a leaflet, runs along the margin to the tip, then, quickly widening, redescends over the midrib towards the base of the leaflet. Frass in the corridor part in fine grains, further up in small clumps. Pupation outside the mine. Older mines turn black and then are somewhat easier to find (Bladmineerders van Europa).

A narrow corridor along the leaf edge, turning and making a blotch in the midrib area (British leafminers).

Larva: The larva is described by Allen (1958), Dempewolf (2001: 57), de Meijere (1925) and in Bladmineerders van Europa.

Puparium: Reddish-orange; posterior spiracles each with 3 bulbs (Spencer, 1976: 117).
