Where to Find a Ribbon Snake

Generally speaking, the ribbon snake is found in North America. But, the specific range of a ribbon snake depends on its type.

Some ribbon snakes are found mostly in the eastern section of the United States while the territory of others extends to western, northern, and southern areas.

All types of ribbon snakes live in the wetlands or near a stream, pond, or lake. They can move with speed on land and in the water. These snakes are most active in the spring and summer during breeding season.

Types of Ribbon Snake

These subspecies of ribbon snake belong to the Colubriae family:

The Eastern ribbon snake (Thamnophis saurita) is found on the east coast of the United States ranging from New York to Florida. Their territory also extends west to the Mississippi River. It has a brown or black body with yellow stripes.
The Northern ribbon snake (Thamnophis saurita septentrionalis) has a territory going through Maine, the northern part of Ohio, Indiana, and Michigan. The Northern ribbon snake also lives in the southern part of Ontario and Nova Scotia in Canada. It has a black or brown body with three stripes of white or yellow similar to the Eastern ribbon snake.
The Western ribbon snake’s (Thamnophis Proximus) range includes Wisconsin and extends south through the United States and into Costa Rica. This is a larger ribbon snake measuring 18 inches to 42 inches.
The Southern ribbon snake (Thamnophis saurita sackenii) lives in the southern section of South Carolina as well as in Georgia and Florida. These snakes are often found in thickets.
The Bluestripe ribbon snake (Thamnophis sauritus nitae) occupies Florida’s Gulf Coast. They are known for their black scales and two blue stripes. Bluestripe ribbon snakes are a little smaller than other types of ribbon snakes. These Gulf Coast snakes can be 18 to 25 inches long.

Ribbon Snake Population & Conservation Status

How to Identify Ribbon Snakes: Appearance and Description

Adult Eastern ribbon snakes have a very thin body that’s 18 to 26 inches long. Its scales are black, brown, or dark green with three yellow, blue, white, or tan stripes running the length of its body. It has one stripe on its back and one on each side. This small reptile has a white or greenish colored belly. It has two dark eyes with a white marking on the scales in front of each one.

How to Identify a Ribbon Snake

  • Black, olive green or dark brown in color
  • Three stripes are white, yellow or blue
  • A slender head matching its narrow body
  • A white marking in front of each eye

Ribbon Snake vs Garter Snake

Ribbon snakes and garter snakes share a lot of features; strictly speaking, ribbons snakes are a type of garter snake. Both snakes have a dark brown or olive-green body featuring three stripes of yellow or white. They both live in North America. Plus, garter snakes and ribbon snakes give live birth. Furthermore, both of these snakes can be a pet. But, despite all of those commonalities, there are things that set them apart.

Though they’re both small snakes, a garter snake has a thicker body than a ribbon snake. A second difference is one you have to look closely to see. A ribbon snake has a white marking in front of each eye whereas garter snakes do not.

In terms of habitat, a garter snake usually lives near ponds, streams, lakes, and marshes. However, they can also make a home away from the water. Alternatively, ribbon snakes restrict themselves to wetlands and shorelines of ponds and streams.

There’s a difference in the diet of these two snakes. Ribbon snakes live around water, so they are known to eat small fish, frogs, and tadpoles. Alternatively, though garter snakes eat frogs and fish, they also include newts and insects in their diet.

It may surprise you to learn that one of these snakes is venomous. Some garter snakes have a mild form of venom and use it to kill their prey. But, though some garter snakes are venomous, this venom isn’t strong enough to affect humans. On the other hand, ribbon snakes are not venomous. These snakes use their great speed to chase and capture prey.

Ribbon Snake: How Dangerous Are They?

Ribbon snakes are not dangerous to people. Recent research shows that some garter snakes have extremely mild prey-specific venom that may cause irritation in people. However, there’s very little research on whether all snakes in the Thamnophis genus have this trait or just a few.

They are fast moving and stay hidden in thickets, marshlands and around ponds. If a person approached this shy snake, it would immediately try to slither away to safety. Even a pet ribbon snake is going to try to escape a situation if it feels threatened.

Of course, like most snakes, a ribbon snake is able to bite. For instance, a pregnant ribbon snake may bite a person who tries to capture her.

Though this snake’s bite does hurt a little, it’s not harmful to a person. If it bites a person, it’s best to wash the area with soap and water, then apply first-aid ointment. If the spot becomes irritated, it’s a good idea to consult a doctor.

Ribbon Snake Behavior and Humans

Unless a person lives near a pond, lake, or marsh, they are unlikely to see a ribbon snake. These snakes are shy and aren’t considered pests.

The size and docile nature of this snake has made it a popular pet with some reptile enthusiasts!
