Giant green smooth caterpillar
We found a 4" lime green caterpillar crossing our deck today. It was as smooth as silk with it's back a little lighter than the sides. On it's tail end was ONE little "eye" in the middle. There were some oval beige spots low on each side There were no other colors except for a very fine sprinkling of tiny black dots near it's head on top. No horn. As it was going along it raised it's butt and plopped a rather large brown segmented poop (?) onto the board. We had been noticing the brown things on the deck for the last few days. They are kind of shaped like a peeled orange except that they are dark brown.
I've been trying to find it online all day and can't find one like it. Does anyone have a clue?
