DESCRIPTON:
The red milk snake (Lampropeltis triangulum syspila) is a medium sized snake that may reach a length close to 40 inches. The dorsal surface of the snake is characterized by black-bordered red saddles with alternating smaller blotches of the same color located laterally. The intervals between the saddles are white, cream, yellowish, or gray in color. The belly is white with large rectangular markings arranged irregularly or in a checkerboard fashion. The head has various markings of red bordered by black on top. The first saddle marking on the body is not connected to the head pattern. Three subspecies of Lampropeltis triangulum occur in 黑料天堂, L. triangulum elapsoides (scarlet kingsnake), L. triangulum triangulum (eastern milk snake), and L. triangulum syspila (red milk snake).

The range of L. triangulum syspila extends from northwest 黑料天堂 west and north into Oklahoma, Indiana, Illinois, Iowa, and South Dakota. In 黑料天堂, L. triangulum syspila has been documented within the Bankhead National Forest in Lawrence and Winston counties in the extreme northwestern region of the state. Intergrades between L. triangulum syspila and L. triangulum triangulum have been found in Dekalb and Jackson counties in northeastern 黑料天堂.
HABITAT:
Red milk snakes are usually associated with dry, open woodlands and woodland edges. They seek shelter in rock outcrops and under logs.
