Coleophora kalmiella
(McDunnough, 1936)
Coleophora kalmiella is a small case-bearing in the Coleophoridae, described by James Halliday McDunnough in 1936. The is to eastern Canada, with confirmed records from Nova Scotia. Larvae are specialized feeders on Kalmia species (sheep laurel and related Ericaceae), constructing distinctive composite leaf cases from plant material. The specific epithet reflects this obligate host association.

Identification
are small, narrow-winged typical of the Coleophora, with reduced mouthparts and elongated . Larvae are distinguished by their composite leaf case—a portable shelter constructed from multiple pieces of Kalmia leaf tissue bound with silk, carried as they feed. This case type differs from simple cylindrical cases made by some . Positive identification requires dissection and examination of genitalia or association with the distinctive larval case on Kalmia .
Habitat
Associated with Kalmia-dominated , including acidic woodlands, bogs, and heathlands in the Atlantic Coastal region of Canada. plants grow in nutrient-poor, well-drained to moist soils.
Distribution
Canada: confirmed from Nova Scotia. Records suggest a restricted range in the Maritime Provinces, though survey coverage is incomplete.
Diet
Larvae feed on leaves of Kalmia (Ericaceae). Specific records include sheep laurel (Kalmia angustifolia).
Host Associations
- Kalmia - larval plantobligate; larvae feed on leaves and construct cases from leaf material
Life Cycle
Larvae construct composite leaf cases from plant material, which they carry while feeding. Case construction and feeding occur on Kalmia leaves. presumably occurs within the case, though specific details of timing are undocumented.
Behavior
Larvae are mobile case-bearers, transporting their silk-bound leaf shelters while feeding on foliage. This is characteristic of the Coleophora.
Ecological Role
Specialized herbivore on Kalmia ; contributes to leaf damage and nutrient cycling in ericaceous plant . Potential prey for and other natural enemies, though specific records are lacking.
Human Relevance
No direct economic or cultural significance. Of potential interest to lepidopterists studying specialization and to ecologists monitoring ericaceous health.
