Range: In Florida, the Florida Rough Green Snake occurs in the central and southern peninsula.

Habitat: Found in mixed hardwood and bottomland forest as well as hardwood hammocks. It is fairly abundant in maritime forest and dunes meadows of Atlantic coast barrier islands. Because of its arboreal habits, it prefers densely leafed trees and shrubs, often at the edges of fields and around ponds.

Comments: HARMLESS (Non Venomous). The Florida Rough Green Snake is arboreal and feeds primarily on insects found on the leaves and stems of trees and shrubs. Its bright green color provides excellent camouflage in vegetation. When disturbed it typically ceases all movement and will sometimes sway to mimic the movement of the surrounding wind-blown foliage. Eggs are laid in mid to late summer under objects in damp areas. The 3-12 hatchlings are 6-8.5 inches (15-21.5 cm) long.

Comparison with other species: There are no other (native) bright green snakes in Florida.
