We are pretty confident that this is a Moth Caterpillar, possibly in the superfamily Noctuoidea, because it looks so similar to the caterpillars in the genus Heterocampa. Here is a similar looking individual posted to BugGuide. We will continue to attempt a more specific identification. Perhaps one of our readers will have a suggestion.
Thanks very much, I have been wondering about what it might be for a couple of years.
