Leaf-mine: Narrow, flat, corridor descending from the leaf tip. Frass in an almost continuous line. The larva usually makes several mines. Mines pale yellow green at first, turning purple later. Pupation external (Bladmineerders van Europa).

Larva: Larva pale yellow, head and prothoracic plate light brown (Bland, 1996a). Hering (1957a), however, states that the head is (dark) brown (Bladmineerders van Europa).

Pupa: Described by Patocka (1999a) (Bladmineerders van Europa).

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