Big butterflies are like a magnet to me. I've not seen any yellow swallowtails here this summer, but there are a couple of black swallowtails and a few monarchs that visit the yard. The flit by and I race to grab my camera, though they seldom settle long enough for me to get a shot. I do love watching them though.
It is a fantastic shot with such clear details and focus.
Well done and a FAV!
