Can you identify this catapiller for me?

It is probably the caterpillar of the polyphemus moth, one of the largest moths in Michigan. The other possibility is the luna moth, but I've raised both a number of times and it looks more like a polyphemus. See

I believe it would be the Polyphemus caterpillar. I have seen the adults before and the cocoon but I don’t recall seeing a caterpillar. Thanks for your identification.
