Identification
Distinguished from other C. suturalis by its smaller body size. The specific epithet 'minutivestis' refers to this reduced size. Further diagnostic features distinguishing it from sympatric Crossidius and other C. suturalis subspecies are not documented in available sources.
Habitat
Associated with stands of Isocoma acradenia var. bracteosa in the San Joaquin Valley of central California.
Distribution
to central California, specifically the San Joaquin Valley region including Fresno County and adjacent areas.
Seasonality
active in late summer and early fall, with peak activity around the third week of September.
Diet
feed on flowers of Isocoma acradenia var. bracteosa. Larval plant is presumed to be the same , though this has not been confirmed.
Host Associations
- Isocoma acradenia var. bracteosa - feed on flowers; larval presumed but unconfirmed
Human Relevance
Collected by entomologists for systematic studies of the Crossidius, particularly for investigations of validity and potential cryptic within the C. coralinus .
