Leaf-miner: A long sinuous gallery with narrow frass-line (British
leafminers).
Oviposition
generally at the leaf upper side, not especially close to a vein.
From there a long and slender corridor starts, with frass usually
in a narrow central line. The corridor often crosses itself, but
rarely a thick vein (Bladmineerders van Europa).
The
mine is also illustrated in the Encyclopedia of Life.
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 yellow, head pale brown (British
leafminers).
The
larva is also described and 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.
