Another Crawly Thing from Door County

This crazy catepillar was found on a grape vine near our Egg Harbor house.  I found it to be a Pandorus Sphinx catepillar.  I read that to ID catepillars one of the most important things is to note where you found it, as the food source tells much about the species.  I wish my photo was clearer.  This was a big guy, about 3 inches long!  Below is the adult.
