...of an Orange Sulphur feeding on wild Golden Aster, and best viewed on black.
This would be a good time to answer a question someone once asked, which was if I ever photographed butterflies on anything but wildflowers...the answer is no. For whatever reason I have this thing about photographing butterflies strictly in their natural habitat/environment, be it feeding on wildflowers or not. Never in one's garden/yard, park or an observatory. Even my own yard, where I might photograph birds, but not butterflies.
