Spicebush swallowtail laying down silk on spicebush leaf to cause it to fold over and enclose the larva for protection against predators. The large "eyes" on the upper part of the body are fake, but appear real to predators such as birds that perceive the worm to be much more dangerous than it really is. The real eyes are much smaller spots located laterally on the tan-colored head capsule. check
