“The rough green snake is the snake with the slightly angeled scales.”

The non-venomous rough green snake is quite a remarkable sight. Identification is quite easy because their bright emerald, green scales are unmistakable. Still, they blend in with the lush plant life around them in their preferred habitats, which include wetlands, uplands, forests, and other areas that are abundant with insects. They are quite smooth and stealthy predators, stalking their prey until they can swallow them whole.

5 Incredible Rough Green Snake Facts!

Here are a few facts you may not know about the rough green snake:

  • The snake’s size typically is about 32 inches, but they can range from 2.5 to 3 feet long.
  • Even though this snake can be hard to find, they have multiple natural predators, including birds, cats, spiders, and larger snakes. They don’t really have any defenses beyond camouflage.
  • Despite their lack of legs, the rough green snake loves to climb trees in pursuit of prey.
  • They only hunt during the daytime, using their flickering tongue and incredible eyesight to seek out food.
  • When kept as a pet, this snake does not like to be handled during their care; it causes them a great deal of stress.

Where to Find Rough Green Snakes

North America is the main location you can find these snakes, specifically in wetlands. Their most common location is in the eastern and southeastern region of the United States, found in abundance from New Jersey to Florida, though they can be found as far west as Kansas and Texas. Though it isn’t common, they may reach New Mexico.

Regardless of the specific location in the country, rough green snakes prefer to live in wetland areas, which is why they aren’t usually found in the arid climates of Arizona and Colorado. They’ll also look for ponds and streams that allow them to swim and look for prey. If you look up, you might even see them hanging in trees.

Scientific Name

The rough green snake, which is sometimes referred to as the grass snake or the green grass snake, has the scientific name Opheodrys aestivus. “Opheodrys” comes from the Greek words “ophios” (“snake”) and “drys” (“tree”), “aestivus” is the Latin word for “summer.” It makes sense that the snake is more abundant during warmer months. This reptile is part of the Colubridae family of the Reptilia class.

Population and Conservation Status

Determining an exact population of this snake is incredibly difficult for two reasons — they camouflage well, and few researchers have looked into their numbers before. According to a 1997 report by the scientist Alan J. Redder, there are about 295 snakes per acre in the United States. Considering these high numbers, there are no conservation efforts as they are considered to be “least concern” by the IUCN.

Appearance and Description

Part of the appeal of the rough green snake is its beautiful emerald green body, making identification relatively easy in the wild. Their smooth scales often feature lighter yellow along their sides, lightening to almost white on their belly. These colors set it apart from some of the less attractive species, which is why so many people want them as a pet.

Identification of the younger snakes can be determined by the blue dots along their head and the rest of their body, though these colors sometimes show on adults. Their rough-looking skin makes it easy to swim or climb trees. While their head is quite small, their body tapers to a much narrower width down the body. They have large eyes, and they measure approximately 2.5 to three feet in size as adults.

Due to the way that they feed, the diet of this reptile has to be carefully managed. They are unable to safely break apart the exoskeleton of certain insects. Their jaw allows them to swallow their prey whole, so it is safest to consume softer insects.

How to identify a rough green snake:

  • Emerald green skin with yellow or white bellies.
  • May have blue dots along head and body.
  • Body thins towards the tail.
  • Large eyes.
  • Small head.

Venom: How Dangerous Are They?

Even with the bright colors of the rough green snake, there’s no need to worry — they are non-venomous. Since they aren’t venomous, there is little point to bite. Instead of attempting to bite anyone, they release an odor from their body that is meant to deter any predators. While venomous snakes tend to use their fangs when stressed, it would take a lot more for this reptile to bite anyone.

Behavior and Humans

Rough green snakes are harmless, since they are non-venomous, and they don’t bite. They aren’t aggressive, and they are often captured in the wild to be sold as pets with an average lifespan of 15 years.

Rough Green Snake FAQs (Frequently Asked Questions) 

Where can I buy a rough green snake?

Rough green snakes are commonly found in pet stores. One of the biggest retailers that offer this species is Petco.

What does a rough green snake eat?

The primary diet of this reptile is comprised of insects, especially crickets, caterpillars, and grasshoppers. It is possible to feed them mealworms, wax worms, and similar insects, but this snake might have a tough time getting past the hardness of its exoskeleton.

How do I care for a rough green snake?

This type of snake is not ideal for a novice pet owner. You’ll need at least a 30-gallon tank to use as a habitat for any adult, giving them plenty of space to move. If you choose to get more than one snake, you’ll need to make the size of the habitat bigger. Their habitat will need substrate, which you need to change often to avoid mold. Since they sleep at night, you won’t likely need to change any of the lightings, though UVB light in the daytime could help with their psychological well-being. If you include any plants, they must be nontoxic, accounting for about half of the habitat.

Provide them with a diet that is rich in insects without hard exoskeletons, like grasshoppers and caterpillars. With the right care, the rough green snake has a 15-year lifespan. Still, it is best not to handle them as they can cause a lot of stress.

How often can you hold a rough green snake?

These snakes are quite shy. Handling them can be stressful, causing them to release an unpleasant odor. As tempting as it may be to pick them up, they are happiest when left to roam their habitat undisturbed.

Is rough green snake poisonous?

No. This snake creates no venom and no poison.

Are rough green snakes good pets?

Absolutely. However, since they don’t like to be handled and require consistent upkeep to prevent mold in their tank, they are best for intermediate-level pet owners.

Are rough green snakes rare?

No. However, they are protected in Georgia.

How much do rough green snakes cost?

The typical price of the rough green snake is just $8 wholesale. The gentle nature of this sweet snake makes it rather easy to find and catch, especially since it isn’t venomous. However, the price seems a lot higher when you consider the initial price of purchasing their habitat, which can be up to $400 for a good enclosure. Each month, expect the price of food and maintenance to range from $20 to $30.

Are rough green snakes venomous?

No. These snakes are non-venomous.

How do rough green snakes hunt?

These snakes use their large eyes to hunt for prey, though their chemosensory systems also help. They seek out prey during the day, stalking it until they can catch and swallow it whole. Their slender body and rough scales allow them to track prey just about anywhere, whether they crawl through the grass or run up a tree.

Are rough green snakes aggressive?

Not typically. That’s part of the reason that the pet snake trade can capture and sell them so easily.

Where do rough green snakes live?

This reptile is endemic to North America, thriving in wetlands.
