Coleophora acamtopappi
Busck, 1915
A case-bearing in the Coleophoridae, described by Busck in 1915. The species is known from California and has specialized larval associations with specific plants. Larvae construct distinctive three-valved silken cases and feed internally on seeds.

Identification
identification requires examination of genitalia or ; no reliable external morphological characters are documented for distinguishing this from . Larvae can be recognized by their trivalved tubular silken case and association with plant seeds.
Habitat
Associated with dry where plants Acamptopappus sphaerocephalus (rayless goldenhead) and Coreopsis occur; likely desert scrub and coastal sage in California.
Distribution
North America; documented from California, United States.
Diet
Larvae feed on seeds of Acamptopappus sphaerocephalus and Coreopsis .
Host Associations
- Acamptopappus sphaerocephalus - larval food plantseeds
- Coreopsis - larval food plantseeds
Life Cycle
Larvae construct a trivalved, tubular silken case. Complete details including number of instars and site are not documented.
Behavior
Larvae create and inhabit a three-part silken tubular case, a characteristic of the Coleophora.
Ecological Role
Seed on specific asteraceous plants; may influence seed set and plant in localized areas.
Similar Taxa
- Other Coleophora species are morphologically similar and require dissection or molecular analysis for reliable identification; larval case structure and plant association provide the most practical distinguishing characters.
