and case-bearer: The larva bores into expanding leaf buds, and later skeletonizes
young leaves, rarely mining a leaf in the usual manner of other Coleophora species. It builds a 'pistol case' from silk and
fragments of leaf and frass. The sides of the case are usually adorned
with hairs from the leaf surface, this feature serving to distinguish
it from the similar case of C.
anatipennella, which feeds on sloe (Prunus spinosa) and other rosaceous trees and shrubs (UKMoths).
brown pistol case of about 7 mm, with a mouth angle of c. 70°
standing almost erect on the leaf. The case is decorated with white
wool, originating from the hostplant. In comparison with C. zelleriella the case is more paunchy (Bladmineerders van Europa).
case is also illustrated in British
leafminers and the Encyclopedia of Life.
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 adult is illustrated in UKMoths and the Encyclopedia
of Life. The male
genitalia are illustrated by the Lepidoptera Dissection Group.
