Black Swallowtail Caterpillars in October

This video highlights the Black Swallowtail and has clips of caterpillars that are just starting out in October. These young caterpillars are trying to survive for 3-4 weeks so they can turn into a chrysalis. Once a chrysalis they are able to overwinter and become a butterfly in the spring. See the host plant, Rue. Also the New England Aster is highlighted. This flower is a magnificent late season bloomer. Will these small Black Swallowtail Butterfly caterpillars make the transformations into beautiful, majestic butterflies?
