Drymobius species grow to .75-1 m (30-40 inches) in total length. Their coloration and pattern vary widely among species.
Drymobius are diurnal species, found in areas of heavy vegetation, almost always near a permanent water source. They are fast moving, and do not generally hesitate to bite if handled.
Breeding occurs in the spring, and clutches of 6-8 eggs are laid in the early summer. The eggs hatch in approximately two months. Hatchlings are 15-18 cm (6-7 inches) in total length.
