Leaf-mine: A narrow gallery leads abruptly to large blotch (British leafminers).

Oviposition on the leaf underside. The mine begins as a very slender winding corridor of 15-20 mm, the second part of which is almost stuffed with frass. The corridor abruptly widens into a blotch with dispersed frass; in large leaves this blotch is almost circular. Mostly the midrib is not crossed, but the mine can occupy the major part of a leaflet. Often several mines in leaf (Bladmineerders van Europa).

Larva: The larva is greenish-white, with dark ventral spots (British leafminers).

Very pale green, head light brown; described by Gustafsson and van Nieukerken (1990a) (Bladmineerders van Europa).

Pupa: Details unknown.

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