and case-bearer: A straw-coloured, slender, three-valved tubular silken case, about
10 mm long. Mouth angle 45° to 60°. Perhaps because of the
plant's dense felt cover, the case is attached with much silk, giving
the holes a conspicuous white margin (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. The male
genitalia are illustrated by the Lepidoptera Dissection Group.
