Life History. A forest and forest-edge snake, which descends to the ground to forage during the day and sleeps in bushes and trees; uses primary and secondary forests. Diet. Hylid frogs are frequently taken as prey. Defense. Kinking its body so that it mimics twigs or leaf petioles is common; it does not hesitate to compress the anterior portion of its body and strike; compression of the body exposes pink skin that contrasts to dark scales. Other common names. Machete savanne, yellow machete, golden tree snake.
