Leaf-mine: The mine is short, with frass irregular, linear. The larva is yellow, gut-line green, and dark ventral spots. There are often several mines in a leaf. The mines are found frequently on seedlings and small plants (British leafminers).

Egg at the underside of the leaf, close to a vein. The mine is a little widening, rather short, tortuous corridor. The first part does not encircle the egg, neither is it lower-surface.The frass line is one third to one half of the width of the corridor. The sides of the corridor are smooth, not scalloped out. Mostly several mines in a leaf, not infrequently crossing each other. Pupation external, exit slit in the lower epidermis (Bladmineerders van Europa).

Larva: The larva is bright yellow with a yellowish brown head and a brown spot on the prothorax. The ganglia of the ventral nervous system are conspicuous. SCS Brown (1947a) and Gustafsson and van Nieukerken (1990a) give a description of the larva (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).
