Scientific Name: Euphilotes enoptes smithi
Smith's Blue Butterfly historically ranged along the coast from Monterey Bay south to Point Gorda, occurring in scattered populations in association with coastal dune, coastal scrub, chaparral, and grassland habitats. Males are bright blue on the upper wing with dusky borders, and females are brown with a band of red-orange markings across the hind wings. The undersides of both sexes are whitish-gray and speckled with black dots. Both have prominently checkered fringes on fore and hind wings, but males have wide black borders and hairy-appearing body.
Main food plants for the Smith's Blue Butterfly are buckwheats; these serve as the larval food source, also the main nectar source and perching site for the adults. The species is very sedentary, rarely moving more than 30 meters from hatching site.
Habitat: Coastal and inland sand dunes as well as steep slopes along the coast where coastal sand dune strand vegetation dominates; area must contain a sea cliff and coastal buckwheat.
Threats: This subspecies is threatened by habitat destruction due to off road vehicles, sand mining, development, and by invasion of introduced plants.
