Leaf-miner: The mine is long, frass linear (British
leafminers).
Egg
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
leafminers).
The
larva is illustrated in Bladmineerders van Europa.
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 species is included in mothdissection.co.uk.
