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 full-grown larva in a bivalved composite leaf case, composed of three leaf fragments of increasing age and decreasing size; the case measures c. 10 mm, the mouth angle is c. 60° (Bladmineerders van Europa).

Has a two year life cycle and ultimately forms a case of three pieces of mined leaf (British leafminers)

Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).

Adult: The adult is not illustrated in UKMoths (check for update). The genitalia are not illustrated by the Lepidoptera Dissection Group (check for update).
