Copperhead Identification: Hourglass Bands and Look-Alikes

A copperhead is a thick-bodied tan to coppery snake whose darker crossbands are wide on the sides and pinched narrow over the backbone, so each band looks like an hourglass from above. The North Carolina Wildlife Resources Commission describes a light brown, coppery or tan background, sometimes grayish or pinkish, with strongly contrasting chestnut-brown hourglass or dumbbell bands. Clemson's Home and Garden Information Center says copperheads are the only snake with this pattern.

Check in this order, from a distance:

• Band shape from the side. The Virginia Herpetological Society notes the hourglass starts on the snake's side. Look at where each band touches the belly: wide there means copperhead-like.
• Color. Pale tan to brown with an almost pink tint (Clemson HGIC).
• Tail tip on small snakes. Young copperheads have a bright yellow tail tip used to lure prey.
• Head and eyes. A triangular, arrowhead-shaped head, a yellow eye with a vertical pupil, and a heat-sensing pit between eye and nostril (Clemson HGIC). Only check the pupil with a zoom lens or binoculars; do not step closer for it.

Adults are usually 2 to 3 feet long and can reach 4 feet (Clemson HGIC).

The Virginia Herpetological Society lists seven non-venomous look-alikes. The quickest separator is where the markings are widest:

• Northern watersnake: the reverse of a copperhead, with bands narrow on the sides and wide near the backbone. Usually near water, sometimes reddish-brown.
• Eastern ratsnake (young): gray or brown blotches on a pale background that do not extend down the sides; adults turn black. Clemson notes the large round pupils.
• Red cornsnake: brighter and redder, with blotches that do not reach down the sides and a round pupil (Clemson HGIC).
• Eastern milksnake: blotches outlined in black.
• Eastern hog-nosed snake: an upturned snout, unique among Virginia's snakes, with a very variable pattern.
• Northern black racer (young): born blotched but uniformly black within two years.
• Northern mole kingsnake: pattern usually fades to plain brown with age, and it is rarely seen in the open.

Clemson adds that non-venomous look-alikes have round pupils and more slender bodies.

Both are pit vipers with vertical pupils, so look at the head stripe and the bands (Wikipedia):

• Side of the head: the cottonmouth has a broad dark stripe running back from the eye; the copperhead has only a thin dark line between the pale and darker parts of the head.
• Bands with age: cottonmouth crossbands fade until older snakes look almost uniformly dark; copperheads keep their hourglass bands for life.
• Snout: the copperhead's snout slopes down and back and looks less blunt.
• Behavior: a threatened cottonmouth often stands its ground, vibrates its tail and gapes to show a white mouth lining. When swimming it usually holds its head at about a 45° angle.
• Range: cottonmouths live in the southeastern US from Virginia to Florida and west to Arkansas and Oklahoma (a few disjunct, possibly extirpated records exist along the Rio Grande in Texas), so outside that area a banded brown snake is not a cottonmouth.

Non-venomous watersnakes, which are also mistaken for cottonmouths, have round pupils and usually flee into the water (Wikipedia).

A corn snake is more colorful and usually redder, with saddle-shaped blotches on the back that do not reach down the sides, and a round pupil (Clemson HGIC; Virginia Herpetological Society). A copperhead is duller tan to copper, its bands are widest on the sides, and it has a vertical pupil. If you cannot see the band shape at the side, treat the snake as venomous and keep your distance.

Possibly. Copperheads give birth to live young in late summer or early fall, 3 to 14 per litter and occasionally up to 20 (NC Wildlife Resources Commission). Wikipedia gives four to seven as typical and each newborn about 20 cm (8 in) long. A small copperhead seen in late summer or fall was therefore born in a litter, and littermates may be in the same area.

Newborns are already venomous (Clemson HGIC). Their bright yellow tail tip is the easiest mark to spot. Keep children and pets away from leaf litter and woodpiles where you saw one, and do not handle a small snake to check it.

Leave it alone and give it space. The NC Wildlife Resources Commission says that is the best response, and suggests spraying it with a garden hose from a distance to make it move on. Many bites happen when people try to capture or kill the snake. Clemson HGIC describes copperheads as not aggressive: bites tend to happen when the snake is stepped on or cornered after it has tried to discourage you.

Get medical help right away; do not wait for symptoms. US Poison Control (1-800-222-1222) says copperhead symptoms develop over 8 to 12 hours and include pain, progressive swelling, redness, bruising and blood blisters; 20 to 25% of bites are dry bites with no venom. Copperhead bites account for about half of the snakebites treated in the United States (Wikipedia) and over 90% of venomous bites in North Carolina (NC Wildlife), and the CDC estimates 7,000 to 8,000 venomous snakebites a year in the US with about 5 deaths.

The CDC's first-aid list:

• Keep calm, and sit or lie with the bite in a neutral, comfortable position
• Remove rings and watches before swelling starts
• Wash the bite with soap and water and cover it with a clean, dry dressing
• Mark the edge of the swelling on the skin and write the time
• Photograph the snake only from a safe distance
• Do not use a tourniquet, ice, cutting, suction, electric shock or alcohol, and do not take aspirin or ibuprofen

A photo is the safest way to identify a snake, and the CDC recommends one taken from a safe distance. Two shots answer most questions on this page:

• A side view of the middle of the body, so the band shape where it meets the belly is visible. Wide at the sides points to copperhead; narrow at the sides and wide on the back points to watersnake.
• A zoomed view of the head, showing any dark stripe behind the eye and, if the lens allows, the pupil shape.

NatureLens can suggest a species from such a photo, with free scans every day. Treat any result as a guide for keeping your distance, never as a reason to approach or handle the snake.
