miner / Stem-borer:
gallery in a young leaf. After having mined for some time the larva

larvae feed inside the stems (UKMoths).
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. The male and female
genitalia are illustrated by the Lepidoptera Dissection Group.
