What Kind Of Snake Is Green With Horizontal Black Stripes?
If this snake was seen in the southeastern US, it could be one of two species, one of which is actually a “mixed breed” of sorts. Eastern Garter Snakes(Thamnophis sirtalis sirtalis) can be greenish with black horizontal stripes, but so can the so-called “Greenish” Rat Snake, a very common snake in the Carolinas and Georgia, which is actually a natural cross between the Black Rat Snake(Pantherophis obsoletta) and the Yellow Rat(Pantherophis quadravitatta). These snakes can be quite large and are often a dull olive green with black stripes, sometimes with faint blotches down the back.
