The rough green snake's eye-catching color makes it unmistakable. It is our only tree-dwelling snake, growing to nearly four feet.
Juveniles are olive to brownish or grayish green.
Eighty-five percent of the diet is spiders and insects. Rough green snakes occur statewide, usually around streams. The color of their back blends perfectly with foliage. To further avoid detection, they sway from side to side when a breeze stirs surrounding branches. In its usual shape, the green snake's lithe body isn't rigid enough to extend horizontally more than a few inches.
