How to Identify a Copperhead Snake (and What It's Often Confused With)
The copperhead is a venomous pit viper found across much of the eastern and central United States, and it accounts for more venomous snakebites than any other North American species — largely because its camouflage is so good that people step on it. The good news: it has one very distinctive marking. Here's how to identify a copperhead and separate it from its harmless look-alikes.
The hourglass bands — the key mark
The copperhead's defining feature is its pattern: dark chestnut or reddish-brown crossbands shaped like an hourglass, saddlebag, or Hershey's Kiss — wide on the sides and pinched narrow across the back — set against a lighter tan or pinkish-brown body. Look at the bands from the side: they're wide at the belly and narrow at the spine. This "hourglass viewed from the side" shape is the single most reliable copperhead marking. Snakes whose blotches are wider on the back than the sides are almost certainly something else.
Coppery head, pit-viper features
As the name says, the head is an unmarked coppery, rusty, or orange-brown color. Being a pit viper, a copperhead has a triangular head wider than the neck, vertical cat-eye pupils, and a heat-sensing pit between each eye and nostril. Copperheads are relatively stout, usually 2–3 feet long. Unlike rattlesnakes, they have no rattle — though, like many snakes, they may vibrate their tail in leaves when alarmed.
Copperhead look-alikes
Several harmless snakes get mistaken for copperheads. The corn snake has bold red-orange blotches (not hourglass bands) with black borders and a checkerboard belly. The eastern hognose is blotchy and flares its head dramatically but has an upturned snout. Young rat snakes and watersnakes can be blotchy and gray-brown, and baby copperheads add confusion because they look like adults but with a bright yellow-green tail tip. Because these overlap, the safest move is a photo check rather than a guess.
Check safely from a photo
Copperheads freeze and rely on camouflage rather than fleeing, so never move in for a closer look. Photograph the snake from a safe distance with your phone's zoom and run it through our free snake identifier to get the species and venom status in seconds.

Identify a Snake FreeFrequently Asked Questions
What does a copperhead look like?
A copperhead has a tan-to-pinkish body marked with dark chestnut hourglass-shaped crossbands (wide on the sides, narrow across the back), an unmarked coppery head, a triangular head with a heat-sensing facial pit, and vertical cat-eye pupils. It's stout and typically 2–3 feet long, with no rattle.
How can I tell a copperhead from a corn snake?
A corn snake is harmless and has bold red-orange blotches with black borders and a black-and-white checkerboard belly — not hourglass bands. A copperhead's bands are pinched narrow across the spine and wide at the sides. Corn snakes also have round pupils and no facial pit.
Do copperheads have a rattle?
No. Copperheads are pit vipers but not rattlesnakes, so they have no rattle. They may vibrate their tail rapidly in dry leaves when alarmed, which can sound like a rattle, but there is no rattle segment on the tail.
