Thank you for this excellent site! I have been looking at hornworms, sphinx moths etc but cannot find this particular species. Over 5 inches when extended, picture is of adult hand. Who is this lovely creature?

Dear C. Suggs,
You were unable to identify your caterpillar because it is not a Hornworm. This is a Giant Silkmoth Caterpillar, or more specifically, a Polyphemus Moth Caterpillar. You may also compare your image to this photo on BugGuide. This individual is most likely preparing to pupate.
Thank you so much! I really appreciate your work in helping people to appreciate insects. I am an unofficial ambassador on behalf of insects as well.
