This larvae is on a plant that I can't remember the name of, it looks like virginia creeper but the leaves are thicker and succulent like. I am thinking Vine Sphinx. Its about 4-5" when its stretched out and almost an inch around. It is actually more on the cocoa side of coloring with very light yellow stripes. There is no rear horn.
I think you're right. Woweee!
After checking again I think its a Satellite Sphinx larvae
still cool looking
aint see not one sphinx cat in my yard this year. usually have them on tomatos but none so far bad year i guess
