Icaricia acmon, the Acmon blue, is a North American butterfly. It ranges mainly in California but can be seen north to Oregon and south through Baja California.

Wingspan is 17-30 mm.[1] 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.[2] Caterpillars are yellow with white hairs and a green stripe down the back.[1]

Adults feed on nectar while caterpillars can feed on deerweed, buckwheats, lupines, trefoils, and milkvetches.[3][1]

Like many other lycaenid butterflies, it has a mutualistic relationship with ants, who protect Acmon blue larvae in exchange for honeydew that the larvae secrete.
