Kansas is home to a surprising variety of snakes, ranging from harmless grass racers to venomous rattlesnakes. This list is designed for outdoor enthusiasts, hikers, homeowners, or anyone curious about the snakes they might encounter in the Sunflower State. Understanding the different species helps with safety, conservation, and appreciation of Kansas’s unique reptile diversity.
Eastern Massasauga Rattlesnake
The Eastern Massasauga (Sistrurus catenatus) is the only venomous rattlesnake native to Kansas. Typically measuring 24 to 30 inches, it has a gray or brown background with dark brown or black blotches along its back. Despite its venom, it is generally shy and avoids humans, but its bite can be serious, so caution is advised when in its habitat, especially in wetlands and tall grass areas.
Western Rattlesnake
The Western Rattlesnake (Crotalus viridis) is common throughout western Kansas. Recognizable by its distinctive rattling tail and a series of dark, irregular crossbands on a gray or brown background, it can grow up to 60 inches long. Its venom is potent but rarely causes serious injury due to its tendency to warn before striking. It prefers rocky hillsides, grasslands, and open plains.
Prairie Rattlesnake
The Prairie Rattlesnake (Crotalus viridis viridis) is a subspecies of the Western Rattlesnake, found mainly in western Kansas. It exhibits a similar appearance but is often more brightly colored, with yellowish or tan backgrounds and dark blotches. This snake favors dry prairies and rocky outcrops, and its presence is vital for controlling rodent populations.
Western Hognose Snake
The Western Hognose (Heterodon nasicus) is a harmless, stout-bodied snake with a distinctive upturned snout used for burrowing. Usually measuring 18 to 30 inches, it sports a pattern of brown, gray, or reddish hues with dark patches. Known for its dramatic defensive displays—playing dead and flattening its neck—it’s a fascinating species that helps control pests like toads and frogs.
Common Garter Snake
The Common Garter Snake (Thamnophis sirtalis) is one of the most widespread snakes in Kansas. It typically measures 20 to 30 inches and has a striking pattern of three yellow or light stripes running down a dark body. Its adaptability to various habitats, from gardens to wetlands, makes it a familiar sight, and it plays a crucial role in local ecosystems by preying on insects, amphibians, and small fish.
Dekay’s Brown Snake
Also known as the Brown Snake (Storeria dekayi), this small, non-venomous species measures about 8 to 12 inches. Its brown or reddish-brown body often features dark spots or a faint stripe along its back. Common in leaf litter and under logs, it primarily feeds on slugs and worms, contributing to pest control in gardens and forests.
Western Ribbon Snake
The Western Ribbon Snake (Thamnophis proximus) is a slender, semi-aquatic snake found near streams, ponds, and marshes in eastern Kansas. It reaches about 20 to 30 inches and has a shiny, dark green or black body with bright yellow or white stripes along its sides. It preys on fish, amphibians, and small invertebrates, making it an important part of aquatic food webs.
Ring-necked Snake
The Ring-necked Snake (Diadophis punctatus) is a small, secretive species measuring 10 to 15 inches. Recognizable by its dark gray or black body and bright yellow or orange ring around its neck, it prefers wooded areas and leaf litter. It primarily feeds on salamanders and small frogs, helping maintain the health of forest ecosystems.
Bullsnake
The Bullsnake (Pituophis catenifer sayi) is one of the largest non-venomous snakes in Kansas, often reaching lengths over 6 feet. It has a yellow or tan background with dark brown or black blotches, mimicking rattlesnakes as a defense mechanism. Its powerful constriction helps control rodent populations, and despite its intimidating size, it poses no threat to humans.
How to Choose
When selecting a snake to observe or study, consider factors like habitat, size, coloration, and behavior. Venomous species like rattlesnakes require caution and respect, while non-venomous species such as garter snakes and bullsnakes are generally harmless. Your purpose—whether for education, photography, or pest control—should guide your choice, along with understanding local regulations and safety precautions.
