Cornsnakes Pantherophis guttatus complex

The Pantherophis guttatus species complex is comprised of at least three species of similar-looking "red ratsnakes" in Eastern North America. They are beautiful and enigmatic members of the community and have adapted to a wide variety of habitats. The map below shows the approximate extent of the range of the three currently recognized species.
