Leaf-miner: The mine is less than 14 mm long, single crease in lower epidermis. The frass random in summer, but in U- or V-shaped lining to cocoon in autumn (British leafminers). Rather small, lower-surface tentiform mine, less than 14 mm long, with one strong fold in the lower epidermis. Pupa in a tough white cocoon that is attached to both the floor and roof of the mine. Before ecdysis the pupa half emerges from the underside of the mine (Bladmineerders van Europa). The leaf-mine is also illustrated in UKMoths and 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). 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, Bladmineerders van Europa and the Encyclopedia of Life. Adult: The adult is illustrated in UKMoths. The species is included in mothdissection.co.uk. Hosts in Great Britain and Ireland:
