Corn Snake

(Elaphe guttata)
Subspecies: Corn, Great Plains Rat

Description:

24-72" (61-182.9 cm). Long and slender; orange or brownish-yellow to light gray, with large black-edged red, brown, olive-brown, or dark-gray blotches down middle of back. Two alternating rows of smaller blotches on each side, extending onto edges of belly scales. Large squarish black marks on belly, becoming stripes under tail. Dark spear-point mark on top of head, and dark stripe extending from eye onto neck. Belly scales flat in middle, with ends angled up sharply. Scales smooth or weakly keeled, in 27-29 rows. Anal plate divided.

Breeding:

Mates in March to May. Clutches of 3-21 eggs are laid late May to July, hatch July to September. Hatchlings are 10-15" (25-38 cm) long, mature in 18-36 months.

Habitat:

Wooded groves, rocky hillsides, meadowland; along watercourses, around springs, woodlots, barnyards, and abandoned houses. Sea level to ca. 6,000' (1,850 m).

Range:

S. New Jersey south through Florida and s. Tennesse to Texas, Mexico, and e. New Mexico, se. Colorado, se. Nebraska to sw. illinois. Separate population in e. Utah and w. Colorado.

Subspecies:

Corn (E. g. guttata), red, orange, or yellow with red, red-orange, or red-brown blotches; s. New Jersey through Florida to Louisiana.

Great Plains Rat (E. g. emoryi), brown to light gray with olive, brown, or dark gray blotches; Louisiana and sw. Illinois west to Colorado and Utah, e. New Mexico and south to Mexico.

Primary nocturnal, but often active in early evening. It readily climbs trees and enters abandoned houses and barns in search of prey: mice, rats, birds, and bats. The name Corn Snake probably originated not from the similarity of the belly markings to the checkered patterns of kernels on Indian corn. It is one of the most beautiful snakes in our range. Captive longevity is 21 3/4 years.
