I’ve been seeing what I thought was a blue wasp on my mountain mint, but couldn’t get one to hold still long enough to be photographed. This evening I finally got a shot where you can definitely see his/her “blueness.”
Blue Wasp on Mountain Mint
I think this must be a Blue Spider Wasp (see http://nativeplantwildlifegarden.com/the-world-as-we-know-it/send-probably-a-spider-wasp-version-2/ for a much better picture).

That is beautiful, Robin. I never knew there was such a thing as a Blue Wasp.
Me neither. They must especially love mountain mint. I found it on the Internet by googling “blue wasp on mountain mint.”
