Leaf-miner: A broad twisting gallery, almost frass filled (British
at the upperside of the leaf. The mine is an irregular, broad corridor
with a conspicuous, broad, black frass line that almost fills the
gallery, leaving only a narrow transparant zone at either side.
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).
Yellow; laying dorsum upwards in the mine. Gustafsson and van
Nieukerken (1990a) give a description (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 genitalia are not illustrated by the Lepidoptera
