Common Snake Species in Minneapolis

Minneapolis snake Common garter snake: These snakes are usually black or brown, with a yellow stripe running down the center of their back and one down each side on the second row of scales and the third row. The stripes on the side of the garter snake blend in with the color of the snake's belly. The area between the stripes is usually checkered with yellow or red patches or black. However, the garter snakes of eastern Minnesota are known to have more yellow coloration than red. For some garter snakes, there might be red coloration on the bottom of their tails. They are 22-32 inches long. They are found throughout Minnesota. During the winter, they hibernate in burrows, rock crevices, or ant mounds to keep from freezing. They feed on frogs, small mammals, earthworms, and insects.

Venomous Snake Species in Minneapolis

Minneapolis snake Massasauga snake: This endangered species can be tricky to identify because they are similar to many other harmless snake species (fox snakes, hognose snakes, bullsnakes, and water snakes). Massasauga snakes are black or grey, with dark brown blotches on their back and smaller blotches on their sides. They have a dark colored rattle at the end of their tails. These medium-sized snakes have a length of 18.5-30 inches. It has a gray-brown background, with a pattern of dark brown patches, with a row of similar patches at the sides. The tail of the massasauga is ringed, with bands having the same color as the dorsal spots. The rattle of the tail is segmented. One of three subspecies of massasauga is found in the upper Midwest and southern Ontario. They also occur on the Wisconsin side of the Mississippi River. They prefer wet habitats like marshes, swamps, and bogs. They also live in open fields, pastures, and woods during the summer. They essentially need areas with sun and shade to regulate their temperature. During winter, they live in burrows, rock cracks, and wood stumps. The massasauga feeds on small rodents like voles and mice. They also eat frogs and snakes.

Minneapolis snake Timber rattlesnake: This threatened snake species may be yellow, brown, or gray with v-shaped markings, with unevenly cut edges across its body. In some species, these v-shaped markings are spotted in the snake's neck region. They have a fine all-black tail, with a tan rattle at the end. The head of the snake is unmarked and triangular, while their necks are narrow. They have elliptical pupils and a heat-sensitive pit between their eyes and nostrils. It is a large snake, with a length of 31.5-48 inches. It occurs in the bluff lands of southeastern Minnesota, forest bluffs, south-facing rock outcrops, and bluff prairies. It can be found in the Mississippi River valley in particular. Their wintering dens are often located in bluff prairies found on steep, south or west-facing hillsides, with rock outcroppings and ledges. In May, these snakes emerge from their dens and sunbathe on ledges and outcroppings. Non-pregnant females and males leave the den around the end of May to the middle of June. The pregnant females remain around their dens until September when they give birth to their young ones live. They feed on rodents like mice and small birds.
