Leaf-mine: The larvae mine the leaves at first, then create small feeding windows (UKMoths).

Small, full depth, hook-like corridor, usually in a vein axil, with a proportionally large larval chamber. The remainder of the mine almost entirely stuffed with frass. At the start if the mine an iridescent egg shell. The larvae soon leave their mine and start living free on the leaf (Bladmineerders van Europa).

The mine is also illustrated in British leafminers.

Larva: The larva is illustrated in UKMoths and British leafminers.

Pupa: The pupa and white ribbed cocoon are illustrated in British leafminers.

Adult: The adult is illustrated in UKMoths (by Rob Edmunds) and the Encyclopedia of Life. The male and female genitalia are illustrated by the Lepidoptera Dissection Group.

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

Time of year - adults: June, and sometimes again in August in the south (UKMoths).
