This dragonfly, Pachydiplax longipennis, may be the only one I have photographed with continued success. I was a little surprised that I found it all the way at the edge of the United States, humoring me as always, but I probably shouldn’t have been. I did manage to shoot a couple other types of dragonflies that sunny day, but the Blue Dasher remains, as ever, the easiest going subject among the insect giants, come North or come South.
