Females dark brown on upper side, extending to a bold terminal line; hindwings have a broad orange aurora. Underside of both sexes light gray to white, lacking the distinct black spots of other blues. Larval host plants include various buckwheats (Eriogonum sp.). Flight season from February to late August.
Diet: Buckwheat (Eriogonum sp.) is thought to be nectar source.
Habitat: Montane communities with buckwheat associations.
Range: Kern and Inyo counties, California; range probably extends into Esmeralda, Eureka, Mineral, Nye, and White Pine counties, Nevada. This subspecies of blues may accidentally occur in the Spring Mountains, Clark County, Nevada.
Comments: The species Euphilotes battoides, as listed in the MSHCP, is part of a complex of five species. The single specimen of blues found in the Spring Mountains, Clark County Nevada, was thought to be a new species. However, it was later identified as Euphilotes bernardino inyomontana.
