Leaf-mine: A contorted gallery, early part in underside of leaf (British leafminers).

Egg at the underside of the leaf. The mine is a gradually widening corridor. Its first part generally is lower-surface, hardly visible from above; further on the mine is full depth. Frass deposition very variable, mostly in a narrow central line throughout, but sometiimes widely dispersed or even coiled (Bladmineerders van Europa).

Larva: The larva is pale yellow, head pale brown (British leafminers). Pale yellow; 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).
