Ecology
Rough Green Snakes can be found in hilly areas where it frequents dry, sparse woodland habitat. They are very good climbers and often bask in low trees and bushes on sunny days. The Rough Green Snake preys mostly on insects such as grasshoppers and spiders. When threatened, it freezes in place and waits for an opportune moment then escapes for the nearest cover.
