Small
(less than 1 cm), full depth blotch, transparent when fresh, starting
at the leaf margin, usually near the leaf tip; frass in scattered
grains. The larva makes an elliptic double sided excision to form
a case. Subsequently, it continues feeding within the case (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 illustrated in 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 illustrated in UKMoths.
The species is included in mothdissection.co.uk.
