Identification, taxonomy, and variation. This subspecies bears cream to whitish colored ventral hindwing spots and a brick red disc. The marginal band along the disc is pinkish rather than buff. Adult wingspan ranges from 45-55 mm. Speyeria hesperis dodgei resembles S. hydaspe forms where these species overlap.

Range. Cascade ranges of Oregon and southern Washington, eastward into Idaho.

Life history. This subspecies is largely confined fir and pine forests and may be seen in canyons, along creeks, and in small clearings and meadows. Dornfeld (1980) briefly described the larva.
