Eastern Milksnake

Lampropeltis triangulum

Also known as Milk Snake, House Snake, Spotted Adder

Eastern milksnakes are secretive constrictors famed for their smooth, glossy scales patterned in rich chestnut or scarlet saddles bordered with black. Primarily nocturnal or crepuscular hunters during warm months, they prowl rodent burrows, stone walls, and decaying logs using an acute sense of smell to track mice and other small reptiles. When startled, an individual often coils defensively, vibrates its tail against dry leaves to mimic a rattlesnake, and strikes if pressed.
