I never really looked closely at this butterfly until now. They have duo-tone eyes!

I had a double-take and look at all the photos I took of this and the other butterfly to validate what I was seeing.  This is going to be a great subject to go more into detail for my magazine!

So next time you are out photographing butterflies, the Cloudless Sulphur might not be the only one with duo-toned eyes!
