Indiana is home to a surprising variety of snake species, ranging from the common and harmless to the less frequently seen and venomous. Understanding these snakes—their habitats, behaviors, and roles in the ecosystem—is crucial for safe and responsible co-existence. This guide will help you identify some of the most prevalent snakes you might encounter in the Hoosier State. Remember, all snakes play a vital role in maintaining a healthy ecosystem, contributing to natural pest control.

Common Non-Venomous Snakes of Indiana

1. Garter Snakes ( Thamnophis sirtalis)

These are arguably Indiana's most common snake. They are slender, with three distinct stripes running down their backs. Garter snakes are highly adaptable and can be found in a wide range of habitats, from meadows to wetlands. They primarily feed on amphibians, small fish, and invertebrates. They are not dangerous to humans.

2. Northern Water Snake (Nerodia sipedon)

Often mistaken for venomous cottonmouths, northern water snakes are much more common. They are robust snakes found near water sources, such as rivers, lakes, and ponds. Their coloration can vary, but they often exhibit dark crossbands on a brownish or gray body. While they may bite if threatened, their bite is harmless to humans.

3. DeKay's Brown Snake (Storeria dekayi)

This small, shy snake is often overlooked. It's a slender, uniformly brown snake with a smooth scale pattern. They inhabit a variety of habitats, including forests, fields, and urban areas. DeKay's brown snakes primarily feed on slugs, earthworms, and insects. They pose no threat to humans.

4. Smooth Green Snake (Opheodrys vernalis)

As its name suggests, this snake has a vibrant green coloration. It prefers moist habitats, such as meadows and forests near water sources. Smooth green snakes are slender and primarily feed on insects. They are docile and harmless to humans.

5. Eastern Fox Snake (Pantherophis vulpinus)

This large, non-venomous snake is becoming increasingly rare in Indiana. It has a distinctive pattern of dark blotches on a tan or reddish-brown background. Eastern Fox Snakes are primarily active at night and feed on rodents and other small mammals. While they can deliver a painful bite if threatened, their venom is not dangerous to humans.

Venomous Snakes of Indiana

Indiana has only two venomous snake species:

1. Copperhead (Agkistrodon contortrix)

Copperheads are medium-sized pit vipers characterized by a copper-colored head and hourglass-shaped markings on their backs. They are ambush predators, feeding mainly on small rodents and amphibians. While their venom is medically significant, fatalities are rare with prompt treatment. Avoid approaching or handling copperheads.

2. Timber Rattlesnake (Crotalus horridus)

This is the largest venomous snake found in Indiana. It's easily identified by its characteristic rattles at the end of its tail, and its dark brown or black crossbands on a tan or grayish background. They primarily inhabit forested areas and are reclusive. Their venom is potent, making prompt medical attention essential if bitten. Maintain a safe distance from timber rattlesnakes.

What to Do if You Encounter a Snake

Observe from a safe distance: Admire the snake without approaching it.
Identify the snake (if possible): Use field guides or online resources to help identify the species.
Never handle a snake: Even non-venomous snakes can bite if they feel threatened.
Keep pets away: Protect your pets from potential encounters.
If bitten by a venomous snake: Seek immediate medical attention. Remain calm and try to remember what the snake looked like.

Indiana's diverse habitats support a variety of snake species. From the forests and woodlands of the southern part of the state to the grasslands and wetlands of the north, each environment provides unique food sources and shelter for different snakes. Conservation efforts to protect these habitats are vital for maintaining healthy snake populations.
