Pandorus Sphinx Caterpillar

Large orange caterpillar
August 13, 2009
I have found many caterpillars similar to this one but they either have a spike on the end or an eye spot on the head or something thats different than ours.
I have searched the web and am stumped. I found only one pic online but it didnt have any info. It was just someones picture.
I have never seen one like this before.
It so far eats grape leaves and lilac leaves.
Stone family.
Rural south central Wisconsin.

Dear Stone Family,
The Caterpillar of the Pandorus Sphinx, Eumorpha pandorus, looses its caudal horn as it molts, leaving only a button as evidenced by your image.
In addition to orange, some Pandorus Sphinx Caterpillars may be green or brown and they are pictured in our archives as well as on Bill Oehlke’s wonderful website.

  1. We live in Southeast CT and discovered our first Pandorus Sphinx Moth caterpillar, Eumorpha pandorus. We’ve never seen this caterpillar before so we were quite intrigued by it’s markings. When do they start their cocoon? It’s mid-October and we’re waiting for our first frost. Will this guy survive? Does the moth migrate?
