Polyphemus Moth – Identification

Q: Over the weekend I was checking on my Japanese maples and noticed something had been dining on the foliage.

Upon closer examination, found a large caterpillar that I need help identifying. Would you have any suggestions?

A: At first I thought this was a luna moth caterpillar…but sharp-eyed Cindy Reittinger noted that it does not have a white line down its sides. Thus, it is a polyphemus moth caterpillar.

Both are giant silkworm moths. See wormspit.com for some excellent pictures of moth and caterpillar.
