I was walking through the porch on my way down to my office, when I glanced out the window and saw something I had never seen before. Dragonflies--thousands of them. The air is filled with them right now, for blocks in every direction. They're swarming from just a few inches above our heads to higher than the tallest elm tree on our street. They are probably feeding on much smaller insects, and are in turn getting gobbled up by various birds swooping through, including woodpeckers and grackles. It's a whole circle of life right in my own backyard.
I didn't take a picture, but found one online that looks similar. For full view, go to their Web site: http://fr.treknature.com/gallery/photo134158.htm
