Coleophora albicans (Zeller, 1849)
[Lepidoptera: Coleophoridae]

Wormwood Case-bearer

Coleophora albicans> (Zeller, 1849).
Coleophora artemisiella
(Scott, 1861)

Leaf-miner, seed / flower feeder: The larva starts to mine the leaves and then later feeds on flowers and seeds (British leafminers, as C. artemisiella).

Squat tubular silken case of 6-7 mm. The front half is covered with felt, the rear half is greyish with some darker length lines. The case is trivalved, the mouth angle is c. 15-30°. The larva not only lives on the leaves, but also feeds in the inflorescence (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 larval case is also illustrated in UKMoths.

The larva leaves the food plant, when fully fed in September, and attaches its case low down on a stem. The case is trivalved and has longitudinal stripes (British leafminers, as Coleophora artemisiella).

Adult: The adult is not illustrated in UKMoths (check for update). The male and female genitalia are illustrated by the Lepidoptera Dissection Group.
