Here is picture of a catepillar with eyes and a goatee I found crawling across my driveway in northeast Texas (Texarkana). The ‘goatee’ is actually not hairy but the bottom of its mouth — just looks like a goatee in the picture. It looks similar to a few on your site but not quite like any of them. I’ve never seen one before — any idea what it is?? You can use the pictures if you want — I enjoyed looking through your site.
We have 11 Caterpillar pages on our site and several images of your species, the Spicebush Swallowtail, Papilio troilus.
