Dragonflies in Palm City

I took these photos in August in Palm City. There were dozens of these small dragonflies flying around, it must have been their mating season. I was using my macro lens with manual focus and no flash, as it was a very bright sunny day, and I used mostly automatic settings in P mode. I might have gotten better photos of dragonflies in flight if I had turned up the f number, and used a high ISO setting to compensate for the smaller aperture.
