The Eastern Smooth Green Snake (Opheodrys vernalis) is a vibrant, slender snake, typically ranging from 18 to 30 inches in length, characterized by its smooth, glossy green scales and pale belly. Found in temperate forests, grasslands, and wetlands across the northeastern and central U.S. and parts of Canada, this non-aggressive species plays a crucial role as an insectivore, controlling insect populations within its ecosystem.
