Leaf-miner: The mine is usually underside, often twisting leaf into a cone
(British
leafminers). The mines can be quite abundant where it is found
(UKMoths).
Lower
surface tentiform mine between leaf margin and midrib; the mine
contracts diagonally, causing the leaf to roll transversely or into
a pepper box (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).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
The cremaster is illustrated in British
leafminers and Bladmineerders van Europa.
Adult:
The adult is illustrated in UKMoths and the Encyclopedia
of Life. The species is included in mothdissection.co.uk.
