The mine begins near the leaf tip and descends towards the base.
The mine occupies the entire width of the blade. Frass initially
scattered, later in an irregular central line. Fully developed mine
c. 8 cm long. Probably the larva is capable of leaving its mine
and restarting in another leaf. Pupation external (Bladmineerders van Europa).
Larva: The larvae of moths have a head capsule and chewing mouthparts with opposable mandibles (see video of a gracillarid larva feeding), six thoracic legs and abdominal legs (see examples).
Grey-green, with a faint white dorsal line; head and prothoracic
plate light brown (Bland, 1996a; Traugott-Olsen and Schmidt-Nielsen,
1977a) (Bladmineerders van Europa).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
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
