Acton Blue, Near Pit River and Hat Creek Confluence, Shasta Co., CA
Mariposa Co. CA
Tiny little butterfly, attracted to a wet spot on the ground. Bright blue inside.
Looking on long-stemmed buckwheat, Erigonum elongatum, for Dammer's dotted-blues but instead found a couple of fresh-looking acmon blues along the upper Canyon Trail at the Big Morongo Canyon Preserve.
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.
