Opheodrys is a genus of small to medium-sized non-venomous colubrid snakes commonly referred to as green snakes. In North America the genus consists of two distinct species. As their common names imply, the Rough Green Snake has keeled dorsal scales, whereas the Smooth Green Snake has smooth dorsal scales.

Species

Species removed from the genus

The genus Opheodrys at one time included two Asian species: O. herminae, which is endemic to Japan, and O. major, which is endemic to Central/South China, Taiwan, N. Vietnam, and Laos. These were removed from the genus by Cundall in 1981[2]

The following subspecies of Opheodrys are no longer recognized:[4]

Geographic range

Green snakes are found throughout the United States, southern Canada, northern Mexico, Japan, China, and Southeast Asia.

Description

Green snakes are so named because they are typically solid green in color dorsally, with a cream-colored or yellow underside. They are thin-bodied snakes that rarely exceed 90 cm (around 36 inches) in length. They have large eyes and blunt shaped heads.

Behavior

Green snakes are often found in dense, low lying vegetation near a permanent water source. They have been known to follow human activity. They rely on their color for camouflage and will usually attempt to escape if threatened.

Diet

Their primary diet is soft-bodied arthropods, including crickets, spiders, moths, butterflies, and grasshoppers.

Reproduction

Green snakes are oviparous.
