Coleophora serpylletorum Hering, 1889
[Lepidoptera: Coleophoridae]

Cliff Case-bearer

Coleophora serpylletorum Hering, 1889. Stett. ent. Ztg. 50: 305.

Leaf-miner and case-bearer: Larva in an untidy composite leaf case of c. 9 mm with a mouth angle of 90°. The larva mines a leaf, usually at the top of a twig, completely out, often while attached to the leaf margin. When the leaf is emptied it is cut off and forms the newest addition to the case (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).

See Emmet et al (1969a) (Bladmineerders van Europa).

Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).

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