Last Saturday I spotted this Blue-fronted Dancer damselfly (Argia apicalis) couple while exploring Riverbend Park in Great Falls, Virginia. I like this shot because it gives a good sense of the differences in coloration between the male and the female of this species. Most of the time when the damselflies are coupled, they are in contorted positions and most of the body of one or the other damselfly is out of focus in my photos. In this case, the damselflies are in the tandem position, but appear to be resting.

Great comparison shot, Mike.
I would say the differences in coloration are amazing!
