Family

Order: Squamata; Suborder: Serpentes; Family: Colubridae; Subfamily: Colubrinae; Genus: Lampropeltis; Species: L. triangulum

Conservation

IUCN Red List: Least Concern. Generally stable, though threatened by habitat loss and road mortality.

Physical Description

Grayish or tan background color with reddish-brown or chocolate-brown dorsal blotches outlined in black. Characteristic light 'V' or 'Y' shaped mark on the back of the head. Features smooth scales, round pupils, and a white/black checkerboard belly pattern.

Size & Dimensions

The specimen appears to be an adult around 60-90 cm. The species typically ranges from 61 to 90 cm (24-36 inches), with a maximum record of 132 cm.

Habitat

Generalist species found in meadows, old fields, rocky hillsides, and deciduous forests; often found around human structures like barns and woodpiles.

Diet & Feeding

Active foragers that use constriction to kill prey. They eat small mammals, birds, eggs, and are known to consume other snakes (ophiophagy).

Reproduction

Oviparous (egg-laying). Females lay clutches of 2 to 17 eggs in early summer, which hatch in late summer or early autumn.

Conservation Status

IUCN Red List: Least Concern. Generally stable, though threatened by habitat loss and road mortality.

Cultural Significance

Named for the folk myth that they would enter barns to 'milk' cows, a physiological impossibility; ecologically valuable for controlling rodent populations.

Notable Features

The 'milksnake' name is a misnomer based on their affinity for barns where rodents—their actual prey—are abundant. They are highly skilled at navigating human-disturbed environments.
