The brown snake (Storeria dekayi) is a small species of colubrid snake.

Geographic rangeEdit

It is native to Southern Ontario and Québec, most of the eastern half of the United States, through Mexico and into Central America.


Dorsally it is brown to gray with a lighter center stripe bordered by small black spots; ventrally it is lighter brown or pink with small black dots at the ends of the ventral scales.[1] Adults usually measure less than 12 inches (30.5 cm), but the record size is 19⅜ inches (49.2 cm).[2] It has keeled dorsal scales, and no loreal scale.


Like its relatives the water snakes (genus Nerodia) and garter snakes (genus Thamnophis) it is ovoviviparous.


It eats earthworms, slugs, and snails.


The epithet dekayi is in honor of American zoologist James Ellsworth Dekay (1792-1851) who collected the first specimen in Long Island, New York.[1]

Subspecies Edit

There are nine recognized subspecies of S. dekayi:
