Here's the same caterpillar I linked to below all grown up.
I do believe this is Sphinx poecila, though I am awaiting confirmation from the experts and/or rearing it out.

Sphinx poecila

This is a fourth instar Sphinx, near identical to one I recently photographed in Northern Ma ( http://www.pbase.com/spjaffe/image/127758481 ) and it's feeding on sweet gale (note the tiny golden punctations on the leaf), one of the favorite hostplants for Sphinx poecila and rarely if ever a hostplant for luscitiosa. I am waiting for my caterpillar to shed into a fifth to confirm an i.d. but I suspect that this individual and mine are of Sphinx poecilla.

sphinx luscitiosa, probably only third or fourth instar

is what both ryan and i thought, so i mailed Bill O and he agreed with us!

this is a good find, as these are fairly rare. lucky you to see such a thing.

cool

Well if Bill agrees with us then it's a fact. I second that, nice find.

hard for me to say

It is a sphingid, but neither of those species. What is the plant that it was found on? That would help ID it.

This one is in the tribe Sphingini.
