Some plants with a broader altitudinal range are found listed in their predominant habitat elevation. All the plant species listed are native to the Sierra's foothills, valleys, and mountains. In addition some are also endemic to here and elsewhere within California – (ca-endemic) ; and some are further endemic to and only found in the Sierra ...
Associated species include snowberry (Symphoricarpos albus), serviceberry (Amelanchier alnifolia), Oregon sunshine (Eriophyllum lanatum) and early blue violet (Viola adunca). Much of the habitat is also covered with introduced species such as Scot's broom (Cytisus scoparius) and yellow hairgrass (Aira praecox). [1] [3]
Speyeria zerene hippolyta is in a clade of three closely related subspecies. In suitable habitat along the U.S. Pacific coast, it is the northernmost one found. Further south, Myrtle's silverspot (Speyeria zerene myrtleae) had a range along the coast from San Mateo County to Sonoma County, California, and Behren's silverspot (Speyeria zerene behrensii) had a range along the northern California ...
The habitat consists of mountain meadows, forest openings and exposed rocky ridges. The wingspan is 45–60 mm. The wings are bright to dull orange brown with dark markings.
