My friend Fred found this on his car. What is it, and why does it look this way?
Hi. It’s a mature spicebush swallowtail caterpillar. These turn yellow or orange at maturity, which some say is adaption to help keep them hidden when one of their larval host plants, sassafras, starts to turn orange in September. More generally, they mimic snakes, as a way to deter predators. The eye spots are pretty convincing, aren’t they?
