Samara-miner: The larva feeds on buds in the spring. In the Summer it feeds on
seeds forming a gallery in the wing (British
leafminers).
Oviposition
on the wing of a key (samara). The larva makes a short superfical
corridor (sometime only the egg is visible) running towards the
seed. Finally the seed is eaten out. Attacked fruits remain on the
plant (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 amber, head yellowish (Emmet, 1983a; Bladmineerders van Europa).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
Pupation in a brownish cocoon, often on the stem (Bladmineerders van Europa).
Adult:
The adult is illustrated in UKMoths. The species is included in mothdissection.co.uk.
