Dragonflies, dragonflies everywhere.

I had an interesting experience today. I went outside to play with the dog and saw many large black shapes flying in low circles in the yard, 20 of them at least. Heading closer, I realized that they where large - very large - blue striped dragonflies. Some of them where large enough that you might mistake them for finches. They where mostly concentrated about three feet to five feet over the ground in just a small part of the yard, about 15x15 feet, give or take. They weren't fighting, just flitting quickly back and forth in large loops. At one point I looked up, and saw lots of them higher up, too. They showed no fear of me standing in the middle of them, treating me like a part of the background. They stayed out for quite a long time. I suspect it was about... 6, 7 pm?
When I eventually went inside, but when I looked them up I couldn't decide what species they were. The closest guess is Blue Skimmer. I looked up why they swarm, and they probably weren't mating, because the males are usually aggressive towards one another in that situation, says the web. Swarming before they migrate, perhaps? Feeding? I'm not sure.
Anyway. It was a very neat experience. Gave me a new respect for just how fast and elegant these insects are.
