The twelve-spotted skimmer id=s a very common dragonfly in North America. They are also one of the more impressive looking as well. The males in particular are quite stunning. The female (shown here) is not as vibrantly colored, but is still impressive nonetheless. As common as they may be, I still only saw one of each sex this year in my area. Not nearly enough. I took this in my back yard in Rockaway, NJ USA with my Nikon D3100 and the 85mm macro lens.
