Marcy's Checkered Gartersnake
Thamnophis marcianus marcianus






This snake typically has an olive, brown, or tan body color with a thin light-colored dorsal stripe. A very prominent black checkered pattern runs down each side of the snake. There is a dark blotch on either side of its neck and these blotches are separated from the corners of the mouth by a light-colored crescent shape. The scales are keeled, the belly is plain, and the anal plate is single.

Adults 18 - 36 inches (46 - 91 cm)

Frogs, fish, and occasionally crayfish

Mates in spring and gives birth to 5 - 20 babies in late June to August. Babies are 8 - 10 inches (20 - 25 cm) long.

Dry grasslands near a source of water

Other Information:
The checkered gartersnake is usually active during the day, but during hot summer months it will search for food in the cooler evening hours.
