Red on Yellow Kills a Fellow

“Red on yellow, kill a fellow; red on black, friend of Jack”

Be happy you learned this little ditty before a foray into the Southern woodland regions of North America. This saying originated in North America as a way to distinguish the venomous coral snake–recognizable by its red, yellow, and black banded skin–from nonvemonous look-a-likes. There are only two species of coral snake found in North America, the eastern coral snake, or harlequin snake (Micrurus Fulvius) and the Arizona coral snake (Micruroides euryxanthus). “Red on yellow” refers to the red and yellow striped bands that run down the the snake’s body. Variations of the phrase include, “Red on Yellow Kills a Fellow, Red on Black, Venom Lack,” and “Red on yellow kills a fellow; red on black, pat it on the back.” Unfortunately the saying’s usefulness wanes outside of North America, where in regions like India, the coral snakes have different color and band patterns on their skin. The image above is of the charlatan coral snake, the scarlet king snake (Lampropeltis Triangulum Elapsoides).

  1. Great article Pierson!

    FYI – The Eastern Coral snake was recently split into two species. The Texas Coral Snake (Micrurus tener) is now recognized as the third species of Coral Snake in the U.S.

    Look up the Sonoran Shovel-nosed snake, found only in Arizona (or see my blog) – if you want to see an exception the the “Red and Yellow kills a fellow” mantra.
