Hoary elfin butterflies typically occupy sites on coastal bluffs. They are closely associated with the kinnikinnick host plant. This subspecies is known from only three sites globally, and two of these are in Oregon.
Limiting factors
With their narrow distribution (subspecies is endemic), hoary elfin butterflies are vulnerable to habitat loss due to development and habitat alteration due to fire suppression. Invasive vegetation may displace native plants that provide adult nectar sources and larval host plants.
Data gaps
Improve understanding of hoary elfin life history. Assess distribution and determine range throughout Oregon.
Conservation actions
Protect habitat known to support hoary elfin butterflies. Restore coastal bluff grasslands.
