Snakes people confuse

Copperhead or Cottonmouth (water moccasin)?

Copperhead Venomous

Cottonmouth (water moccasin)

Cottonmouth (water moccasin) Venomous

Also venomous. Juvenile cottonmouths have many dark spots and speckles inside their dark crossbands (copperhead bands have none or at most one). The Florida Museum says adult Florida cottonmouths are typically uniformly dark, but SCDNR says cottonmouth color ranges from dark brown and black to olive drab and yellow-tan, so a pale snake is not ruled out. The copperhead's eye is not obscured by the dark facial band typical of the cottonmouth. Cottonmouths are almost always associated with wetlands.

Copperhead or Northern water snake?

Its dark bands form a 'reverse hourglass': wider across the back and narrower on the sides (the copperhead's are narrow on the back, wide on the sides). Older water snakes can look solid dark.

Hatchling and yearling rat snakes have irregular blotches, not hourglass bands, and turn virtually all black as adults (NJ Division of Fish and Wildlife). New Jersey says no other snake there has the copperhead's hourglass pattern; Delaware DNREC says the same for Delaware.

Copperhead or Eastern hognose snake?

Eastern hognose snake Non-venomous

Named by Delaware DNREC and Rutgers as a frequent copperhead misidentification. Use the hourglass test: in Delaware only the copperhead has dark hourglass crossbands narrowest at the center of the back.

When snakes are active in Kentucky

Records of snakes in Kentucky peak in April to June. They show when people record snakes, not how many there are (about month bars).

910 records of snakes in Kentucky by month (GBIF, CC0 and CC BY records).
  • Copperheads give birth to live young in late summer or early fall. KDFWR

If you are bitten or stung

Call 911 or Poison Help at 1-800-222-1222 right away. Poison Help connects you to your local poison center, any time of day.

Official advice from KDFWR:

  • If you find a snake and are unsure whether it is venomous, leave it alone; do not try to catch or kill it. KDFWR
  • Do not handle a freshly killed venomous snake; it can still bite by reflex. KDFWR
  • Snakebite: call 911 or Poison Help at 1-800-222-1222 and get to the nearest hospital right away. KDFWR
