Smooth Green Snake - Opheodrys vernalis


A green, smooth-scaled, snake measuring nearly 2 feet (61 cm) in length. Dorsal coloration is bright green. Belly is pale yellow or white. Young are darker, nearly gray dorsally.



Lays 3 to 11 eggs in midsummer.



Lives in upland habitats, usually on the ground.



Feeds mainly on spiders and insects.



The species occurs from Nova Scotia west along the Canadian border to North Dakota, southeast to northeastern Illinois, east to northern New Jersey. Spotty distribution throughout the upper Midwest and even into New Mexico, Colorado, Utah and the southeastern coast of Texas. One isolated population in Chihuahua, Mexico. In Connecticut it is localized, but at least one known populations seems to occur in every county.



Not federally protected.



An incredibly difficult snake to find. It blends in wonderfully with its surroundings and can easily go unnoticed in a habitat. Contrary to popular folklore, it is not venomous.
