Near the trail between a woodland and grassland, rested on two flowers both the kind shown in the picture, only saw one in the area.
There were many other butterflies like this one around the path. This butterfly stayed still long enough for a handful of people to get a picture. The butterfly was small, about 5 centimeters in width.
The markings on the underside of the wings seem a little different than the usual Acmon Blue, but I'm not sure what else it could be.

The Acmon Blue (Plebejus acmon) is a North American butterfly. It ranges mainly in California but can be seen north to Oregon and south through Baja California. The tops of the wings are blue with dark edges in males and brown in females. Its underside is white with black spots for both sexes with a red-orange band on the hindwing. Adults feed on nectar while caterpillars can feed on buckwheats, lupines, trefoils, and milkvetches.
