Drymobius is a genus of colubrid snakes commonly referred to as neotropical racers, which are endemic to the Americas. There are four species recognized in the genus.
Geographic range
They are found predominantly in Mexico and Central America, but they range as far north as the southern tip of Texas in the United States, and as far south as Brazil in South America.
Description
Drymobius species grow to .75–1 m (30-40 inches) in total length. Their coloration and pattern vary widely among species.
Habitat
They are found in areas of heavy vegetation, almost always near a permanent water source.
Behaviour
Drymobius are diurnal species. They are fast moving, and do not generally hesitate to bite if handled.
Diet
Their primary diet consists of frogs and toads.
Reproduction
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.
