This photo was taken in my backyard, and identified using a somewhat limited Peterson's guide. Please email me if the i.d. is incorrect. The setup was quite different from what I used at the Butterfly House. It was a bright, sunny day, and I just spotted this butterfly spending some time on flowers we had out back. I needed to shoot quickly, so used a minimum of equipment. Canon 100/f2.8 Macro lens, ISO 100, f/16, 1/200 second (Av mode), 550EX on camera with Stofen Omnibounce, hand-held.
