Leaf-miner: A narrow gallery leads abruptly to large blotch (British
on the leaf underside. The mine begins as a very slender winding
corridor of 15-20 mm, the second part of which is almost stuffed
with frass. The corridor abruptly widens into a blotch with dispersed
frass; in large leaves this blotch is almost circular. Mostly the
midrib is not crossed, but the mine can occupy the major part of
a leaflet. Often several mines in leaf (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).
The larva is greenish-white, with dark ventral spots (British
pale green, head light brown; described by Gustafsson and van
Nieukerken (1990a) (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. The genitalia are not illustrated by the Lepidoptera
