Coleophora trigeminella Fuchs, 1881
[Lepidoptera: Coleophoridae]

Scarce Thorn Case-bearer


Coleophora trigeminella Fuchs, 1881. Ent. Ztg. Stett. 42: 462.


Leaf-miner and case-bearer: Tubular silken case of only 5-6 mm. The case is weakly constricted near the anal end, and strongly just behind the mouth. The case is sharply bent there; therefore the mouth angle is 0° and the case lies adpressed to the leaf. The fully developed case normally is trivalved. Larvae at the underside of the leaf (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).

Described by Emmet et al. (1996a) (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 genitalia, but not the female genitalia (check for update), are illustrated by the Lepidoptera Dissection Group.
