Leaf-miner: A blotch mine is formed on the on leaf-lobe with central frass (British leafminers).

Primary blotch in the tip of a leaf segment, without any preceding corridor. Frass in a central patch, pasted to the upper epidermis; when not feeding the larva retreats here. Around the centre some more frass grains are present, but not in an apparent spiral order. Oviposition is at the underside of the leaf at about 1 mm from the leaf margin (in Leucoptera malifoliella, with which confusion might be possible, the egg is deposited well away from the leaf margin) (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).

Pale green; see Gustafsson and van Nieukerken (1990a) for a description (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.
