Copperhead vs Corn Snake

Corn snakes and copperheads can both look tan to orange, which is why people confuse them, and why a quick check of the pattern matters. Only the copperhead is venomous. The corn snake is a slender, non-venomous snake that is found in every county of mainland Florida and avoids people and pets.

Pattern is the best tool. A copperhead's bands are narrow at the spine and flare on the sides like an hourglass, while a corn snake has distinct blotches with black borders along the back. If you can see the belly, the black and white checkerboard of a corn snake confirms it, but never pick up a snake to check.

Copperhead vs Corn Snake side by side

Last verified October 2026. Typical values; individual animals, products and local prices vary.

When you are looking at which

Copperhead

• The back shows hourglass bands that are wide on the sides and narrow across the spine.
• The snake is heavy and stocky, in a coppery tan with a plain, arrow-shaped head.
• A zoomed photo shows a cat-like vertical pupil in a yellow eye.
• A small snake has a bright yellow tail tip.

Corn Snake

• The back shows separate blotches outlined in black, in orange, red or brownish tones.
• A spear-shaped mark runs along the top of the head and neck.
• The belly, if visible, has a black and white checkerboard pattern.
• The snake looks slender and brighter orange, and it has round pupils.

How this works

The quiz scores five cues: back pattern, head marking, belly, build and pupil. Each answer scores for copperhead or corn snake, and the side with more answers is the result. Answer only from photos or from a safe distance, and skip any question you cannot answer without moving close to the snake.

Pattern and belly are the strongest cues. Young snakes, shedding snakes and unusual color forms can blur the picture, so if you are unsure, treat the snake as venomous and keep away. A snake that is shedding, injured or very young can look different from the typical adult described here.

• Clemson Home & Garden Information Center: Identifying Copperhead Snakes, Copperhead hourglass pattern, vertical pupil, stocky build and corn snake contrast. (checked October 2026)
• Florida Museum: Red Cornsnake, Corn snake size, blotches, spear mark, checkerboard belly and behavior. (checked October 2026)
