Leaf-mine: Full depth, somewhat inflated and puckered mine with scattered frass. Pupation outside the mine (Bladmineerders van Europa).

The larva lives in the flower-buds and mines in the leaves (UKMoths and Belgian Lepidoptera).

Larva: The larva is illustrated in UKMoths and illustrated in Encyclopedia of Life.

Pupa: The larva pupates in a tough cocoon on or under the surface of the ground (Belgian Lepidoptera). The pupa is illustrated in UKMoths.

Adult: The adult is illustrated in UKMoths and the Encyclopedia of Life. The male genitalia, but not the female genitalia (check for update), are illustrated by the Lepidoptera Dissection group.
