Leaf-miner: The short full depth corridor mine is made in the leaf in September
and the larva then hibernates on the axil of the leaf, making a
web and feeding the next spring (British
leafminers). In the spring they feed on the leaves from within
a silk web (UKMoths).
larvae make a small full depth corridor in autumn. They pass the
winter in a hiberaculum outside the mine, later they live free in
a spinning (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).
Free-living larva- Body slender, reddish brown; head light brown; prothoracic plate dark brown. Laterally a bright white, broad but to the rear quickly narrowing length line on thorax of foremost abdomen segments. A similar dorsal line, but narrower and shorter, begins behind the head (Bladmineerders van Europa).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
