Description: Average adult size is 18-44 inches (45.7-111.7 cm), record is 72 inches (182.8 cm). Adults are orangish-brown with black bordered orange, red, or brownish blotches. The belly is usually a black and white checkerboard pattern, though orange may also be present. The underside of the tail has 2 black stripes. There is a spear-shaped pattern on the head and neck. The scales are weakly keeled, and there are 27-29 dorsal scale rows at midbody. The pupil is round. Juveniles are similar in appearance to adults, but may be more brownish in coloration.

Range: The Eastern Corn Snake occurs throughout Florida. Outside of the state, it occurs west to the Mississippi River and north to southern New Jersey.

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


Comments: HARMLESS (Non-Venomous). The Eastern Corn Snake is primarily active at night. It is both a terrestrial burrower 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 corn crib 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 were paid for using it by eating the pesky rodents.

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