Description:
Harmless. Named for the weakly keeled, bright green scales covering its body. A slender-bodied serpent with a white to yellow-colored belly. The tail is very long, almost 40% of total body length; the tail is used as a counterweight when the snake is moving through branches of bushes and brush. Young are miniature adults.
The snake is bright green above and has a yellowish belly, affording it excellent camouflage in green vegetation. It grows up to 40 inches (102 cm) in length and is very thin. There are 17 dorsal scale rows at mid-body and the scales are keeled. The pupils are round. Juvenile coloration is similar to adults, but not as brightly colored.
Adults normally grow 560-810 mm (22-32 inches) in TL; largest specimen from Kansas: female (KU 45334) from Elk County with TL of 877 mm (34½ inches) collected by Henry S. Fitch on 8 July 1957; maximum length throughout range: 45¼ inches (Conant and Collins, 1998).

Distribution:
Known from moderately to heavily wooded areas in southeast Kansas from the Arkansas River drainage north to the Kansas River basin.

Natural History:
Active during the day from April to early October. Prefers bushes or shrubs along the edge of streams and swamps; sometimes found on open brushy ridges, under rocks, or crossing roads. Very difficult to observe because its color blends so well with green vegetation.
Burt and Hoyle (1935) stated that they may be found under rocks in prairie ledges in the early spring, but later they are most likely to be located in vegetation, especially in shrubs and trees.
Breeding occurs in spring or autumn; up to 10 eggs per clutch are laid in June or July. Specializes in feeding on caterpillars, grasshoppers, crickets, dragonflies, damselflies, and spiders.
The Rough Green Snake breeds in spring, and sometimes again in fall. Females lay 3-12 eggs, occasionally in a communal nest shared by more than one female. Up to 75 eggs have been found in one such nest. The nest site varies: under boards, under bark in rotting stumps, in deep mulch, or under a rock. Hatchlings from spring breeding typically emerge in August or September and are about 20 cm in length.


Occurrence Activity:
White dates indicate there is at least a single recorded occurrence on that date. The darker blue a date is, the greater the relative number of observations for that date.
Remarks:
This small, slender snake blends in well with shrubs, trees, and grasses it spends most of its time in. Most encounters with this species occur as it attempts to crossroads.
