Leaf-miner: A contorted gallery, early part in underside of leaf (British
leafminers).
Egg
at the underside of the leaf. The mine is a gradually widening corridor.
Its first part generally is lower-surface, hardly visible from above;
further on the mine is full depth. Frass deposition very variable,
mostly in a narrow central line throughout, but sometiimes widely
dispersed or even coiled (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).
The larva is pale yellow, head pale brown (British
leafminers).
Pale
yellow; described by Gustafsson and van Nieukerken (1990a) (Bladmineerders van Europa).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).

The adult is not illustrated in UKMoths (check for update). The species is included in mothdissection.co.uk.
