Leaf-mine: The mine is upper side, oval, over midrib or side-vein - the upper epidermis flimsy with one strong crease (British leafminers).

Unlike other species that form an upperside mine, the surface is not papery, but quite glossy and heavily creased. The mine begins green and then turns orange or brown when more mature (UKMoths).

Upper-surface, fairly small, almost flat tentiform mine with a characteristic yellow green colour. The mine has a single, moderately strong, fold. Generally the mine is positioned over a lateral vein. Frass in a clump in a corner of the mine (Bladmineerders van Europa).

Larva: The larva is illustrated in British leafminers and Bladmineerders van Europa.

Pupa: The pupa is formed in a white cocoon (British leafminers).

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

Hosts in Britain:

Hosts elsewhere:

Time of year - larvae: July, October (British leafminers).

Time of year - adults: Two generations, with a flight period in May and August (UKMoths).
