Leaf-miner: The larva forms a blotch mine on the underside of a leaf, often quite small, but puckering the leaf noticeably (UKMoths). The mine is 10-15 mm long, 1-6 creases in lower epidermis (British leafminers). Small lower surface tentiform mine; the lower epidermis is greenish yellow and weakly folded. Pupation within the mine in a cocoon that in the summer generation is so flimsy that sometimes it seems to be missing, while in the autumn generation it is quite tough. All frass in a corner of the mine (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). Whtish, with an orange-yellow spot dorsally on the sixth abdominal segment. See Grandi (1931a, 1933a) for a description of the morphology (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 Bladmineerders van Europa. Adult: The adult is illustrated in UKMoths. The species is included in mothdissection.co.uk. Hosts in Great Britain and Ireland:
