I have been seeing quite a few common green darner dragonflies on my adventures as the temps have increased. Green darners are large dragonflies that are strong fliers. I typically see them flying over ponds or fields on the hunt for mosquitoes or other small flying insects. The difficulty with photographing green darners is that they often fly for a long time, and they can fly for quite a distance, so finding one that has landed can be difficult. Even though this darner did not land for me I got lucky and it decided to do some hovering. It took me a while to get it in view and get the lens focused before it moved, especially since most of the work that I do is using manual focus, but eventually I was able to get some pics of the darner in flight.
Green darners are very similar to birds in many ways. These dragons migrate south much the same way that many birds do. In fact researchers at Princeton found that they exhibit some of the same traits that birds do when they migrate, such as migrating during a cold front with favourable north west winds or skirting large bodies of water during migration. Now they have returned to their summer breeding grounds and they are hunting for food and soon they will begin mating, much the same way that migrating birds are.
