During a walk through a forest preserve recently, as I traversed a pond encircled with trails, I spotted these dragonflies. They were content to let me get reasonably close, but I did get dive-bombed a few times.
The closest I can get to a matching identification is that of the male Common Whitetail Skimmer, where I read that their typical habitat is near slow or standing water. And they are very territorial and will drive off other males. I guess they recognized me.
Both were taken with a Sony NEX 6, the first at 50mm using the 16-50mm lens, the second at 210mm, using the 55-210 zoom. I think the 16-50 is sharper but the second, taken with the zoom, has really nice bokeh. Tweaked in Lightroom 4.
