Leaf-miner: The mine is long, frass linear (British
at the underside of the leaf, close to a vein. The mine is a very
long and slender gallery, hardly widening at all. Frass in a continuous,
very narrow central line. The corridor follows veins over long distances,
obtaining thereby an angular appearance (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).
The larva is a greenish white, head brown (British

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 not illustrated by the Lepidoptera
