Leaf-mine: The mine is contorted, starting underside, frass linear (British leafminers).

Egg at the underside of the leaf, mostly close to a vein. The mine is a fairly slender corridor that even towards the end hardly widens. The first part consists of a some close loops around the oviposition site; this part generally is lower-surface. The later part is much less contorted, with a frass line that occupies one third to one half the width of the gallery. The sides of the corridor are irregularly scalloped out. Usually no more than one mine per leaf. Pupation external, exit slit in the lower epidermis (Bladmineerders van Europa).

The mine is also illustrated in UKMoths.

Larva: The larva is yellow, gut-line green (British leafminers).

Pale yellow, head light brown; lies venter-upwards in the mine. See Gustafsson and van Nieukerken (1990a) for a detailed description (Bladmineerders van Europa).

Pupa: Details unknown.

Adult: The adult is illustrated in UKMoths. The genitalia are not illustrated by the Lepidoptera Dissection Group (check for update).
