This was a dream come true moment for me. I've seen plenty of Black Swallowtails over the years, but I haven't had many opportunities to take photos because the individuals I encounter are either wary of being approached or are beating their wings so wildly as they feed that the photos I take all end up being discarded because they are motion blurred. This individual was also beating its wings wildly, but it stopped in this wings open pose for a second or two every now and then. That's when I took this photo.
