Special needs

This species occurs in only one known location globally: approximately six square miles of ash-pumice habitat with spurry buckwheat located southeast of Crater Lake, OR.

Limiting factors

Conservation actions

Maintain and restore existing habitat with appropriate host and nectar plants.
