Occasionally, individuals from the southern peninsula are anerythristic, meaning they lack all red pigment, which gives them a grayish body with black blotches. Notice the black and white checkerboard pattern in the belly.

Range: It is found throughout peninsular Florida. The species ranges west to Louisiana to north to southern New Jersey.

Habitat: Commonly found near pinelands, hardwood hammocks, swamps, agricultural fields, and residential areas.

Comments: . The corn snake is primarily active at night. It is both a terrestrial borrower and extremely good climber. It is found under rocks and logs, and in trees under bark and within palm fronds.

It feeds on lizards, frogs, rodents, and birds and their eggs.

It lays eggs. Breeding occurs from April-June, 3-40 eggs are laid during the summer, and newborns hatch from July-September. It can live up to 22 years in captivity.

The name, 'Corn Snake', is a holdover from the days when southern farmers stored harvested ears of corn in a wood frame or log building called a crib. Rats and mice came to the corncrib to feed on the corn, and corn snakes came to feed on the rodents. It is hard to imagine a better man-made habitat, with rafters and logs on which the snakes could climb and hide, and they paid for using it by eating the pesky rodents.

Comparison with other species: The mole kingsnakes (Lampropeltis calligaster) have a light Y-shaped pattern on the back of the head and neck, a clouded brownish belly, and lack a distinct neck.
