Gray-blue (butterfly) – State Wildlife Action Plan

Gray-blue (butterfly)

Photo is needed for this SGCN.

The wingspan is 22–26 mm. The males are a shiny, light gray-blue color above, with a black border on the apical margins breaking into a row of black dots on the hind wing. Females are russet-brown above with blue and sometimes orange highlights and often have white spots across the wings. Both
sexes have prominent dorsal forewing and dorsal hindwing cell bars and often submarginal black rings on the dorsal hindwing. Beneath, the ventral hindwing spots are fused and occluded by heavy white blotches against a dark tan background. Prominent black pupils occur in all of the white spots except one (in the hindwing cell). The klamathensis subspecies is the only representative of this species in Oregon.

Overview

  • Species Common Name Gray-blue (butterfly)
  • Species Scientific Name Agriades podarce klamathensis

Ecoregions

Special needs

This species is a riparian-wetlands and wet meadow associate, typically found in high elevation (5100 ft. to over 6500 ft.) wet meadows or along lakeshores. Larvae rely on several species of shooting stars (Dodecatheon spp.) as host plants. Adults feed on multiple species, including yellow composites. Adult males are known to visit mud puddles.

Limiting factors

Meadow habitat is subject to plant succession and trampling by livestock and hikers. Patchy distribution makes it vulnerable to local extirpation.

Conservation actions

Monitor existing populations and habitat. Survey suitable habitat for new populations. Manage habitat to provide preferred host plant species. Maintain hydrologic regimes in occupied habitats.
