Big Blue Dragonfly - Aeshna canadensis
Voyageurs National Park - Ash River Visitor Center, St. Louis County, Minnesota, USA
July 29, 2016
Seen perched up in a tree, having just caught another insect. It was crunching on it while perched. Was quite large, but since it was just about out of reach, I do not have a great size estimate on it.

Aeshna sp - Male
It is a male mosaic Darner. I can't see enough detail in the thorax to be sure of the ID. Gut reaction is Canada or Lake. If you can add a cropped version of the picture with the blue background that is a close-up of the head and thorax, an ID might be possible. There are shadows that make that tough too.

Hooray!
Thanks for taking a look at it. At least I was looking in the right genus (I know very little about dragonflies...). Here is the cropped image. Hopefully it helps.

Aeshna eremita?
The deep notch on the first thoracic stripe confirms that it is a Lake or Canada Darner. I believe that I see a black line at the seam in the face and the notch looks better for Lake Darner. Not 100% but would lean that way.

facial line
even at this angle the line should appear thinner and darker on A. eremita and I would expect an even deeper notch. The shape of the cerci would be another distinguishing feature if they were clearer.

Does this shot help?
See picture #4. Is this helpful, or do you need a different angle?
