Jim and I spotted this nearly 3” long caterpillar working its way across our dried lawn. It may have come from a nearby big-leafed maple, and we’re trying to figure out where it might be headed, perhaps to pupate?

Our books don’t show any similar butterfly caterpillar anyway.

Any suggestions would help.

Thank you all!

could it be a Polyphemus moth caterpillar?

Thanks, Stephanie, I think that's it! We have seen adults here before. Both larva and adult are very impressively large!

Very cool! I would love to see a photo of one of your adults the next time one floats by!
