Coleophora milvipennis Zeller, 1839
[Lepidoptera: Coleophoridae]

Buff Birch Case-bearer


Coleophora milvipennis Zeller, 1839. Isis: 208.


Leaf-miner and case-bearer: Larva mining leaves, the blotches brownish. The final case is 8-11 mm long, slender, and fixed at 45° to leaf surface, with anal end laterally compressed. The case has a serrated keel due to formation from the edge of a leaf (British leafminers).

Spatulate leaf case. Strikingly slender, bivalved case, 8-11 mm long, with a slight curve at the rear end, that is keeled and often toothed. The end is laterally compressed. Mouth angle 45°. The full depth mines often are conspicuously brown (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).

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