Leaf-mine: A short linear-blotch mine, beginning with a small yellowish-brown pustule. Pupation external (Spencer, 1976: 315, 317 (fig. 569)).

Greenish, later blackish, tortuous or irregularly star-shaped, upper-surface corridor, rather strongly widening in the end, and usually forming a secondary blotch. Frass in the first part of the mine in two ill-defined rows. Primary and secondary feeding lines present, but short and criss-cross. Pupation within the mine; the anterior spiracles penetrate the upper epidermis (Bladmineerders van Europa).

The mine is an upper surface linear mine, becoming a blotch, with two rows of frass (British leafminers).

Larva: The larva is described by de Meijere (1938), Allen (1958), Dempewolf (2001: 167) and illustrated in Bladmineerders van Europa.

Puparium: Yellowish-brown; posterior spiracles each with an ellipse of some 20 bulbs (Spencer, 1976: 315). The puparium is illustrated in Bladmineerders van Europa.
