Leaf-mine: An irregular whitish, linear mine, frass in conspicuous black strips (Spencer, 1972: 72 (fig. 235), 77; Spencer, 1976: 409 (fig. 717), 410).

Wide corridor, generally upper-surface but not rarely, partly or entirely, lower-surface. Primary feeding lines distinct. Frass at first in grains, later in short thread fragments to two close rows along the sides. Pupation outside the mine (Bladmineerders van Europa).

An irregular, whitish gallery, usually upper side, but sometimes starting lower side. Frass conspicuous (British leafminers).

Larva: The larva is described by de Meijere (1926) and illustrated in Bladmineerders van Europa.

Puparium: Yellow (brown); posterior spiracles each with an ellipse of up to 13 bulbs (Spencer, 1976: 410).
