In 2007, the scientific named changed from Elaphe alleghaniensis to Pantherophis alleghaniensis. Even historic sighting information is useful. Please report all sightings of this species in Vermont. The Eastern Ratsnake has been designated a Species of Greatest Conservation Need (high priority) in Vermont’s Wildlife Action Plan and is threatened in Vermont. This species has a state natural heritage rank of S2 (rare). The Eastern Ratsnake is typically found in and around old buildings, old fields, and edges near rocky areas and ledges. You can learn more about this species and see some video footage by checking out this clip from our Rattlers, Peepers & Snappers DVD. Get more detailed identification and life history information by downloading the chart here. Adult North American Racers (also black as adults) are solid black with a solid white or gray belly. By the time ratsnakes reach three feet in length they are mostly black. In addition, the blotches on the young Eastern Ratsnakes have slightly extended corners so that they are more “H” shaped, rather than round. Young Eastern Ratsnakes under 20 inches long have a pattern similar to Eastern Milksnakes, but they do not have the white “Y” on the back of the head that milksnakes have. Adults may be 5-6 feet long (the longest documented in Vermont is 75 inches). This changes to a black and white checkerboard pattern as you move toward the tail and then finally turns to a solid dark color under the tail. The underside is white under the chin and throat. The adult Eastern Ratsnake is black, but usually shows remnants of its juvenile blotched pattern and some flecks of white between the scales.
