Leaf-miner:
Gradually widening mine in the base of the blade; the sides very
irregulary scalloped out. In the end the blade may be eaten out
completely. When lit from behind the mine is not uniformly transparant,
but rather yellowish green and mottled because the larva leaves
parts of the leaf tissue uneaten, and does not feed full depth.
Pupation external (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).
Described by Parenti (2005a). The larva is dark olive green, almost
black (Bladmineerders van Europa).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
Described by Parenti (2005a) (Bladmineerders van Europa).
