Leaf-miner: The mine is often in the lobe of the leaf. There are many creases in lower epidermis, which is strongly contracted, causing lobe or leaf-edge to fold over (British leafminers). Rather small, lower-surface, tentiform mine with a yellow-green epidermis that has a number of folds. Pupation within the mine. The pupa of the summer generation in a quite flimsy cocoon; in the autumn generation there is more, golden, silk. All frass in a clump in the distal angle of the mine (Bladmineerders van Europa). The mine is also illustrated in 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). 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). The pupa is illustrated in British leafminers and Bladmineerders van Europa. Adult: The adult is illustrated in UKMoths. The species is included in mothdissection.co.uk.
