Plains gartersnake

This snake has a thick dorsal stripe that runs down the center of the back from head to tail. It can be yellow to reddish-orange. It has a thinner yellow stripe on either side of the main dorsal stripe, with a black checkered pattern between the stripes. This is how it got the name "garter." The labial scales above the mouth often have dark black vertical lines among pale scales. It has keeled scales, the belly is plain, and the anal plate is single.
