Spotting

Lovely, Xylophanes pluto, Pluto Sphinx. Were the underwings orange?

I did see the underwings. But, it does look very similar to the darapsa myron

This looks like a species of Sphinx Moth (Family Sphingidae). I am not sure of the exact species. There are a couple that can have green coloration. Did you happen to see the underwings? If you did, what color were they?
It reminds me a bit of Darapsa myron - Virginia Creeper. See what you think:
