I remember the day I took this photograph. It was hot. Mid-July. We had been walking along a dusty path beside a field overgrown with tall grass and wildflowers that seemed to thrive despite the heat. We were nearing the end of our walk when this swallowtail landed on a nearby flower. It was in no hurry and I was able to take several photographs. I have not seen a black swallowtail again and was pretty pleased to have had this opportunity.
