The blue dasher is one of the most common species of dragonfly in North America. They are also one of the bravest as you can see here. I had to get my lens pretty close to get this shot, and she never even blinked. Not that they blink at all, but you know what I mean. ;)
This was taken near Lake Telemark in Rockaway, NJ USA with my Nikon D3100 and 85mm macro lens.
