The long-nosed snake, Rhinocheilus lecontei, is a medium-sized snake native to the south-central and southwestern United States, as well as to much of Mexico. In Utah, the species is commonly found in the western part of the state. Long-nosed snakes are nocturnal and are only active during the spring, summer, and fall seasons.

The long-nosed snake eats primarily lizards and lizard eggs, but snakes, rodents, and small birds are also consumed. The species lays its eggs during the summer; eggs hatch in two to three months. The average clutch contains between four and eleven eggs. Although the long-nosed snake is not venomous, the black, red, and white coloration of the species bears a superficial resemblance to the venomous western coral snake. The western coral snake, however, does not naturally occur in Utah.
