Did I get this right? Are there "dirty" acmons, and why isn't this a Lupine Blue?
This photograph is not upside down. The butterfly is upside-down. Were I to turn the butterfly right-side up, then the photograph would be upside-down. It's a topsy-turvy world.
Plentiful near the beginning of the trail.
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.
