Plains Gartersnake (Plains Garter Snake)
An attractive, medium-sized snake of wet meadows and marshes. Very similar to the other gartersnakes, but it usually has a yellowish-orange stripe down the middle of the back. The general color is greenish gray, olive, or brown. A light stripe on each side may be yellow, green, or blue. The area between the light stripes usually has an alternating double row of black spots. The light green upper lip has black bars along the edges of the scales. The belly is gray or greenish gray with a row of black spots along each side. Like other gartersnakes, when captured or molested, this snake will smear a musky secretion from glands at the base of the tail.
