I found this is the yard and he isn’t really moving hardly….probably reading to spin a cocoon. Do you know if it will turn into a moth or butterfly? I’m guessing a moth..
This looks to us to be the prepupal caterpillar of a Blinded Sphinx, Paonias excaecata. We have this image of a pre-pupal Blinded Sphinx Caterpillar in our own archives or you can compare to this image on BugGuide. Blinded Sphinx Caterpillar pupate naked underground. They do not spin a cocoon.
