We’ve had some nights below freezing recently, and the day I took these didn’t get much above the mid 50s (10 C) so I was surprised to see any dragonfly.
I spent some time with my “Dragonflies and Damselflies of the East” book and searching online. I did not even come up with Blue Corporal as a possibility.
The ID was provided by Odonata of the Eastern United States Facebook group, with one very confident ID as a Juvenile male Blue Corporal Dragonfly, with several assents.
