Coleophora coracipennella (Hübner, 1796)
[Lepidoptera: Coleophoridae]

Blackthorn Case-bearer


Tinea coracipennella Hübner, 1796. Europ. Schmett. 8: 67.
Coleophora coracipennella
(Hübner, 1796).


Leaf-miner and case-bearer: The larva initially makes a blotch mine in the leaf, which it then excises to form its case. The larva overwinters in its case before resuming feeding in spring. A new case, 6-7 mm long, is then constructed from a further blotch mine (UKMoths).

The second case is indistinguishable from C. spinella and C.prunifoliae (British leafminers).

The final case is a tubular leaf case, 6-7 mm long, light brown at first, darker later. The rear end is trivalved, the mouth opening is around 45°. The larvae live at the underside of the leaves, and make sizable full depth mines.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).

Pupation occurs within the case in June. In common with many other Coleophora the case is attached to the upper side of a leaf during this stage of the moths life cycle (UKMoths).

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