15 Pages of Caterpillars… No Luck
I searched your 15 pages of caterpillars frontwards, backwards and sideways trying to figure out who I captured on camera a couple of years ago in Peachtree, Georgia. Maybe this is something common that’s just in a different instar than a pic you have posted? Whatever the case, I thought you might be interested.
We actually do have several images of Inchworms, the caterpillars of the Geometrid Moths, that have camouflaged themselves with plant material. BugGuide has specimens from the genus Synchlora that exhibit this unusual behavior. The appearance of the plant parts on your specimen is resulting in the appearance. Other than the choice of plant material, there is one image on BugGuide that looks very much like your caterpillar. Inchworms are also called Spanworms.
