and case-bearer: As with other Coleophorids, the larva forms
a case from the leaf, in which it overwinters. The case formed by
this species is long, slender and frequently woolly in appearance
composite leaf case of 8-10 mm, rather strongly compressed and keeled,
with a mouth angle of 30-45° (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).
The adult is illustrated in UKMoths.
genitalia are illustrated by the Lepidoptera Dissection Group.
