Cliff Case-bearer

The Cliff Case-bearer, Coleophora species, is a small micro-moth in the family Coleophoridae whose larvae construct and carry portable, protective cases made from plant material, silk, and their own excrement, hence the name case-bearer. The larvae feed within these cases on the leaves or seeds of specific host plants, often grasses or forbs growing on cliff faces, rocky slopes, and coastal headlands. The Coleophoridae is a very large family of small moths with thousands of described species, many of them host-plant specific. Adult Cliff Case-bearers are typically narrow-winged, with lanceolate, often buff or gray-brown wings held tightly against the body at rest. Identification to species level requires microscopic examination of genitalia. The larvae overwinter in their cases on the ground before resuming feeding in spring. The ecology of cliff case-bearers is closely tied to their specific host plants, and they are sensitive to changes in vegetation management and plant community composition on cliffs and rocky habitats. As with many microlepidoptera, specific information on distribution, host plant associations, and conservation status requires detailed taxonomic study of the exact species in question.
