Coleophora albicosta (Haworth, 1828)
[Lepidoptera: Coleophoridae]

Gorse Case-bearer

Coleophora albicosta (Haworth, 1828)

Seed-feeder / borer and case-bearer: Initially the larva feeds on seeds, boring into seedpods. It makes a case from calyx parts in late summer, which is covered in hairs, and continues feeding by boring into more seedpods (British leafminers).

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).

Adult: The adult is illustrated in UKMoths. The male and female genitalia are illustrated by the Lepidoptera Dissection Group.

Hosts elsewhere: Currently unknown.

Time of year - larvae: July - April. In November the larva makes a case from silk, in which it over winters (British leafminers).
