I'm going with Blue Dasher for this dragonfly.
The trick in getting good dragonfly pictures is to shoot them on stable perches where the wind is not whipping them around. It also helps if they are big.
Per a New York Times article, "The most remarkable of the giant arthropods were the giant dragonflies, Meganeuropsis permiana and its cousins, with wingspans that reached two and a half feet. They were the largest insects that ever lived. These large species thrived about 300 million years ago when much of the land was lush and tropical."
