The appearance of adult snakes differs greatly from juveniles. At a young age, the black spots on the skin are usually dark brown with black or really dark brown edges. Juveniles also have a dark line from the jaws to the eyes and between the eyes. This line disappears as the snake ages.

Other similar-looking snakes that the western fox snake can be confused with: The nonvemomous Pacific gopher snake (especially the subspecies bullsnake), the nonvenomous western hognose snake, venomous rattlesnakes and the venomous cottonmouth snake or copperhead snake. In Iowa, several crossbreeds between western fox snakes and bullsnakes have been found, making a definitive ID even more difficult.

Size

Like all species from the rat snake family, fox snakes are a relatively long snake species in the United States. An adult western fox snake grows between 36-56 inches (93-143 cm).

Diet an Habitat

The western fox snake inhabits a variety of habitats, mostly moist environments close to rivers and lakes. They feed mostly on small mammals and birds or birds’ eggs. The snake is an excellent climber. The fox snake kills its prey by constriction. It wraps its body around the prey and contracts its muscles. Through this, the prey is either crushed to death or suffocated before it is eaten whole. They are often found near farms where they prey on rodents.

Bite

When it feels scared, threatened or irritated, the western fox snake often shakes its tail like a rattle. Because of this behavior and its appearance, foxsnakes are often confused with similar-looking rattlesnakes. However, foxsnakes are not venomous and harmless for humans or larger pets. They only bite if provoked.

If the snake feels cornered or is handled, it can release a foul smelling musk that smells similar to foxes. This defensive behavior and its smell has given the snake its common name, the foxsnake.

Geographic Range

The western foxsnake is found in the Northern Central United States, exclusively west of the Mississippi River. Therefore, it can be found in the following States: Minnesota, Iowa, Eastern South Dakota, Eastern Nebraska, Northeastern Kansas and Missouri.
