Ruby-spotted Swallowtail

I know that this Ruby-spotted Swallowtail looks a lot like the Pink-spotted Cattleheart I posted a few days ago. But if you look close the spots are a little different in size, shape and colors and even the shape of the butterfly. Subtle differences is just one thing that makes labeling butterflies difficult! I did not get shots of both sides of this guy, partly because it started to rain.

Butterflies . . .  Flowers that fly and all but sing.
