Description
Garter snakes grow one to three feet long, and range in color from black to brown. Three yellow stripes run down their bodies; one down the middle of the back and one on each side of the body. A dark checkered pattern is visible between these stripes. They have yellow bellies mottled with black. Females are generally larger than males.
Habitat
These snakes can be found in a variety of habitats across the state. They are common in areas around water, such as marshes or forested ponds. Grassy fields and stone walls are also places garter snakes may call home. Many people may see them in urban and suburban areas, especially in yards.
Behavior
Garter snakes will eat almost anything that fits in their mouth, including worms, slugs, invertebrates, frogs, and fish. When threatened, it is common for them to flee. They release an unpleasant smell when handled, and may bite. These snakes are non-venomous, but some people may be allergic to their saliva, causing swelling and increased pain when bitten. In the middle of the summer, they give birth to ten to forty live young.

Ribbonsnakes generally have thin, slender bodies and narrow heads, compared to the round and stocky garter snakes. Ribbonsnakes also have longer tails, unpatterned white lips, and a white spot in front of their eyes. Garter snakes commonly have a dark checkered pattern between their stripes, while ribbonsnakes are patternless.
