Lupine Blue Butterfly - Plebejus lupini
The Lupine Blue Butterfly has a Spring and early Summer flight in the Sierras, May through July. They don't have anything to do with Lupines but lays eggs and feed on buckwheats. This one is sipping the nectar of Eriogonum umbellatum. The males will come to the edges of a damp puddle. Both males and females will feed on Pussy Paws. The best way to get a butterfly to come to your garden is to plant the plants that they feed upon..
