Sphinx Moth?
I saw this caterpillar on a blueberry bush in a meadow in Shenandoah. I know for sure that it is a sphinx moth caterpillar, but I’m having trouble pinpointing the species. I’ve looked through your website and guidebooks but with no luck. Since it was eating the blueberry leaves, I’m guessing that it might be a Huckleberry Sphinx?
Thank you! Your site has been a wonderful source for identifying all the bugs I come across. Shenandoah National Park, Virginia

Blinded Sphinx Caterpillar

Blinded Sphinx Caterpillar

Hi Holly,
Your caterpillar is a Blinded Sphinx Caterpillar, Paonias excaecata.  Many times this caterpillar is green, but BugGuide has examples of this mottled color variation.  Bill Oehlke’s very comprehensive Sphingidae site does not depict this color variation.  As he is currently compiling comprehensive data on species distribution, we are copying him on this reply.  He may also request permission to post your photo to his site.
