Young larvae make irregular corridor-like or blotch-like mines from
a silken tube. The mines contain almost no frass (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).
Greenish yellow, with five pale pink length lines; head yellowish
brown, prothoracic and anal plates green (Jansen, 1999a; Bland et
al., 2002a) (Bladmineerders van Europa).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
Described by Patočka and Turčáni (2005a) (Bladmineerders van Europa).
The adult is illustrated in UKMoths. The male
and female genitalia are illustrated by the Lepidoptera Dissection Group.
