butterfly (about 0.75 - 1 inch across) and has silvery blue wings with
black spots and an orange band. Females tend to be more brown than blue.

similar Blue butterflies is that the orange band is found on the
hindwing only and the fact that the Acmon Blue can be found flying in
Arizona most times of the year (other Blues typically fly in the summer
The blue wings of the Acmon Blue
in the photographs give it away as a male.

of buckwheats and lotus as well as freckled mildvetch and sweet clover.
The Acmon Blue is found throughout Arizona (except in the southwest) as
well as in California, Nevada, Utah, Colorado and New Mexico.
