Yellow-bellied Water Snakes

Louisiana has abundant wildlife, including reptiles such as snakes and turtles. All are welcome in Yvonne's backyard wildlife habitat.


Reptile: Nerodia erythrogaster (Forster) includes Yellow-bellied and Blotched Water Snakes

Non-venomous (Non-poisonous) Plain-bellied Water snakes are found in every southeastern state in the U.S. They are stout reptiles with dark brown, gray or greenish gray backs and bellies that range in color from yellow to red. In Louisiana, the Yellow-bellied and blotched water snakes occur. Even though these snakes are comfortable in water, they are often found on land, quite a distance away from a body of water. The Plain-bellied Water Snake is another of the many non-venomous, beneficial snakes that live in the south.

Yellow-bellied Water Snake is the Most Common Plain-bellied


A relatively heavy bodied, moderately long (up to 62 inches) with a pattern of alternating dorsal and lateral dark blotches readily visible, partially obscured or totally lacking on a gray or dark brown background (the pattern always visible in juveniles); belly some shade of yellow to red with relatively few dark markings. Baby Plain-bellied water snakes have banding patterns that resemble those of banded watersnakes, but have unmarked bellies and bands that are incomplete in the neck region. Plain-bellied water snakes are non-poisonous snakes.

Louisiana Water Snakes

Two Plain-bellied sub-species are found in Louisiana.

Yellow-bellied Water Snake (N. e. erythrogaster) - Its adult dorsal pattern is visible only as narrow mid dorsal bars, if visible at all. The Yellow-bellied water snake occurs all over Louisiana.

Blotched Water Snake (N. e. transversa) - The adults retain the blotched pattern found in all juveniles. The blotched water snake occurs only in the Prairie.

Snakes of the Southeast

Snakes of the Southeast is a "must have" book for anyone who is interested in snakes. The information is up to date and very thorough and the many full color photographs just seem to jump off of the page. It is an excellent, all-round book.


Habits, Habitat and Reproduction


Nerodia erythrogaster (Yellow bellied water snake) is found in the ponds, sloughs, bayou, streams, rivers, lakes and swamps in the hill country of Louisiana and also in the drainage ditches and flooded rice fields of the lowlands. During the summer months, it is known to wander quite a distance from water than any other Nerodia species and they rarely bask. They are frequently one of the earliest water snakes to be seen in the spring and they spend more time on land that most other water snakes.

Yellow-bellied water snakes feed on small fish, crawfish and leopard frogs, which they capture and eat alive without constricting.

Plain-bellied water snakes mate from April until mid June. Females give birth to from 2-55 (18 is normal) live young during August or September.

Predators of Plain-bellied Water Snakes include largemouth bass, kingsnakes, cottonmouths, egrets, red-shouldered hawks and red-tailed hawks.

Interactions with Yellow-bellied Water Snakes


We have had several encounters with large Yellow-bellied water snakes in our habitat in Southeastern Louisiana and most of them occurred on land, near our house. For two years in a row we found a pair of Yellow-bellied water snakes on our front porch and patio where we have a small water feature in an old iron wash kettle. It was quite a surprise to see the large snakes and at one point they decided that the patio drain pipe would make a nice den. My husband was able to catch them and release them down at the river so that they wouldn't eat the fish and frogs in the bass pond near the house.

Snakes Are Hunters

Did you know there are over 3,000 kinds of snakes in the world? There are garter snakes, water snakes, rattlesnakes, and boa constrictors. Some are very, very big and some are tiny. Some glide over the ground, some climb trees, some even swim. But there is one thing they all have in common: snakes are hunters. A Reading Rainbow selection.

I walked outside my back door in se tx i saw this same snake 3 1/2 in. animal control came and got it and stated it was non venom

MerryChicky on April 29, 2012:

I found a snake in the back yard today (and gave it it's space), then got online to see what it was. It sure does look with the water snake you've got on here. We've got a large ditch out back, so I figure he/she wandered over to check out the healthy population of lizards hanging out in the yard. Thanks for the info!

A pretty lens with great photos! Not fond of snakes but you have presented this one well.

Yvonne L B (author) from Covington, LA on February 14, 2009:

[in reply to Treasures-By-Brenda] It's all my husband's fault. He has been in love with snakes since he was a kid and would play in Audubon Park in New Orleans. He converted me, so now we both appreciate the beauty and wonder of reptiles.

Treasures By Brenda from Canada on February 14, 2009:

Well done page, I'm wondering what started your interest in snakes!
