3D Black Swallowtail Caterpillar

The black swallowtail caterpillar feeds on plants in the carrot family such as parsley, dill, and fennel. As it grows, it changes from a tiny black and white larva into a vibrant green caterpillar striped with black and dotted with yellow. These colors help signal to predators that it may taste unpleasant. After several weeks of feeding, it forms a chrysalis and begins its transformation into a striking black swallowtail butterfly.
