Leaf-mine: A gallery, with coiled frass in central part (British leafminers).

Oviposition generally at the upperside of the leaf, and not far from the leaf margin. The mine is a rather wide corridor, that often crosses a vein, and almost invariably runs from somewhere near the leaf margin in the direction of the midrib. Its first part is quite narrow, with a narrow central frass line. The next section is wider, and here the frass is distinctly coiled. In the final section the frass lies somewhat more irregular, and in a rather narrow central zone (Bladmineerders van Europa).

The mine is also illustrated in the Encyclopedia of Life.

Larva: The larva is whitish-yellow, head pale brown (British leafminers).

Described by Gustafsson and van Nieukerken (1990a) (Bladmineerders van Europa).

Pupa: Details unknown.

Adult: The adult is illustrated in UKMoths and the Encyclopedia of Life. The genitalia are not illustrated by the Lepidoptera Dissection Group.
