I just stopped at a gas station outside Springfield, MO and thankfully happened to notice this amazing creature. I figured that it was some kind of Sphinx Moth.
I've definitely seen others like it in my days, but never this color. Since I love camouflage (it's my favorite color) I was really excited to see it. When I looked it up, I found out that the actual name of it is the Fabulous Green Sphinx Moth. I'm not sure who actually named it, but I agree, this is one fabulous creature!
I barely had time to verify before it took off and flew away, so here's the proof.
