Ceraunus Blue (female)

A very small, female butterfly from the Blue subfamily. It's white with a brown pattern and black spots on the underside. I did not see the tops of the wings. "Two prominent black spots on leading edge of hindwing, below. One or more prominent large eyepots along the outer edge of hindwing (regional variations - southeastern ones seem to have one, southwestern ones, two)." - BugGuide " Upperside of male light blue with a darker narrow border; female dark brown, often with wing bases blue. (Wingspan) 3/4 - 1 1/8 inches (2 - 3 cm)." - Butterflies and Moths of North America.
