The chief difference of Eastern Tailed Blues seems to be that the males are much lighter in overall coloring on the inside of their wings than the females. This side-by-side comparison shows off that very telling feature, with the male on the left and the female on the right.

Both Butterflies were photographed on May 5th, 2008.
