Lienig & Zeller, 1846Wingspan c. 11mm.
One of several British species of Coleophora with bronzy metallic forewings, this species occurs commonly in parts of southern England. The species was only separated from C. frischella in 1976 and so the distribution detail is clouded.
The adults fly in grassy habitats during June and July and can be attracted to light.
Red clover (Trifolium pratense) is the foodplant, the larva feeding on the developing seeds and building a case closely resembling a floret of the foodplant.
