We saw this caterpillar hiking in Vermont this fall and we are wondering what it is and what it will look like as a butterfly or moth.

Your caterpillar is one of the Tiger Swallowtails. There are several species with ranges that overlap in Vermont, including the Eastern Tiger Swallowtail and the Canadian Tiger Swallowtail. It is very difficult to tell the species apart. The caterpillars of both species turn from green to brown or sometime orange just prior to pupation. You can see a photo of an adult Tiger Swallowtail in our archive.
