and case-bearer: The full grown larva lives in a dull black pistol case of c 9 mm
that, with a mouth angle of 80-90° stands erect on the leaf.
Characteristic is the presence of some ear-like flaps. At least
after the hibernation the larvae do not mine any more, but rather
cause skeleton feeding (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).
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 male
and female genitalia are illustrated by the Lepidoptera Dissection Group.
