Welcome to dgrin, 4huskers.
Can you post a bigger image so that we can really see it here on dgrin, rather than just the link?
I love swallowtails and have photographed dozens and dozens over the years, so I really do like swallowtails, and look forward to seeing your image.
I just saw your response. I tried to post the image, but I can't get it to attach the image. Only the link inserts.
