a flat case, made out of leaf fragments, and cause window feeding
at the leaf underside (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).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
The adult is illustrated in UKMoths (by Nigel Richards) and the Encyclopedia
of Life. The male and female genitalia are illustrated by the Lepidoptera
