and case-bearer: The larva builds a case from leaf fragments,
adding sections as it grows, creating a long narrow and distinctive
large, composite leaf case of 10-15 mm length, the fully developed
case consisting the three succesive leaf fragments. Case light brown,
bivalved; mouth angle c. 45° (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).
Described by Suire (1961a) (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 Dissection Group.
