Sighted a large caterpillar 3" long and 1/2 to 3/4" wide. It was feeding
on wild grape leaves in upstate New York. It was a grey-brown color,
maybe just a tinge of green. There were 8-10 white spots along each side
which varied in size from approximately 2 to 4 mm. No hair or spikes. My
first thought was some type of sphinx, but I'm thinking sphinx have a
horn on the tail end and this one didn't. Any help?
