Another Yam Hawkmoth?
February 26, 2010
We saw this unusual bug on the wall at our hotel in Myrtle Beach, SC back in Sept. When I went looking to identify it, I found your site. We are from PA so the insect is totally foreign to us. Thanks for your help.

Tersa Sphinx

Dear Cindy,
This is a Tersa Sphinx, Xylophanes tersa.  Interestingly, Tina from Hawaii, who submitted the photo of Hippotion boerhaviae, which we originally misidentified as a Yam Hawkmoth, believed her moth resembled a Tersa Sphinx.  You may read more about the Tersa Sphinx on Bill Oehlke’s excellent website.
