Leaf-mine: Forms a large transparent blotch mine - with a central spot, where the frass collects. This spot is usually red-brown (British leafminers).

Brownish, full depth, inflated blotch, usually at the leaf margin, often with a central brown spot. Oviposition at the leaf underside. Often 2-3 larvae in a mine. Pupation outside the mine (Bladmineerders van Europa).

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

Pupa: Pupation on the bark in a cocoon (British leafminers).

Described by Patocka (1999a), Patocka and Turcani (2005a) (Bladmineerders van Europa).

Adult: The adult is illustrated in UKMoths by Guy Meredith. The male genitalia, but not the female genitalia (check for update), are illustrated by the Lepidoptera Dissection Group.
