Among the many dragonflies out on a hot July afternoon, this Blue Dasher (Pachydiplax longipennis) stood out in the crowd. He energetically patrolled his territory and chased just about any dragonfly that neared, especially those that sported a touch of blue. I found him at multiple points along the pond’s shore—he turned up just about everywhere. And, the little dasher did not seem to be intimidated by the larger dragons, such as the Eight-spotted Skimmers and darners. He jumped right in and challenged them all.
Note that this male has not fully matured. A fully mature specimen would have blue-green eyes. Also, the blue pruinosity visible on the abdomen can develop on the thorax, giving this fellow and even bluer look.
