Leaf-mine: The narrow mine begins a few cm below the tip of the leaf and runs downwards, sometimes along the leaf margin, sometimes in the center of the leaf. After hibernation the larva probably begins a new, similar mine, that becomes quite long, ending near the leaf base. Frass in a brown, regularly interrupted line. Pupation external; pupa attached to the leaf, not in a cocoon (Bladmineerders van Europa).

Larva: Yellowish white, head shining light brown; the prothoracic shield consists of two greyish, triangular, widely separated sclerites. Their shape and position is species-specific; see Steurer (1973a) for an illustration (Bladmineerders van Europa).

Pupa: Details unknown.

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