Wildlife Spotting

I have looked into this more, and this looks to be a wasp from genus Agenioideus. The bluish wings and fly-like head match a variety in this genus really well. I'll have to look up more about them though.

You could be right. There are a few different types of Mud Daubers out there, so it could be one of those or one of what you said.

After a bit of research, I believe your wasp most closely resembles wasps from Genus Trypoxylon, Subgenus Trypargilum. I am not sure exactly which species this is, though. There are a few options and I am not sure you have enough to get this down to a species. Very cool wasp! http://bugguide.net/node/view/1322992/bgimage http://bugguide.net/node/view/1192213/bgimage

Do you have any other views of this lovely insect?

This is a lovely wasp. I do not believe this is a Mud Dauber. The color pattern and shape of the body, as well of the color of the wings, do not seem to match to me. http://bugguide.net/node/view/6610

That look like a Mud Dauber Wasp. They generally aren't aggressive and stings are uncommon with them. In Tennessee, you may hear the name dirt dauber for these guys. :)
