Etymology

The specific name, lecontei, commemorates American entomologist John Lawrence Le Conte (1825-1883).^[4]

Description

The long-nosed snake is distinguished by a long, slightly upturned snout, which is the origin of its common name. It is tricolor, vaguely resembling a coral snake with black and red saddling that almost looks like banding, on a yellow or cream-colored background, which can look somewhat like yellow banding. Cream-colored spots within the black saddles are a distinct characteristic of the long-nosed snake. It differs from all other harmless snakes in the United States by having undivided subcaudal scales.^[5] They average around 30 inches (76 cm) in total length.

Behavior

R. lecontei is a shy, nocturnal burrowing snake. It spends most of its time buried underground.

Diet

The long-nosed snake feeds on lizards, amphibians, and sometimes smaller snakes and infrequently rodents.

Reproduction

R. lecontei is oviparous, laying clutches of 4-9 eggs in the early summer, which hatch in the late summer or early fall.

Defense

The long-nosed snake is not apt to bite, but will release a foul smelling musk and blood^[6] from the cloaca as a defense mechanism if harassed.

Habitat

Geographic range

Subspecies

In captivity

The long-nosed snake is not often found in the exotic pet trade as it frequently rejects rodent-based diets that are most readily available for captive snakes.
