Thamnophis radix
thamnophis radixAlso known as Plains Garter Snake, Western Plains Garter Snake
Plains garter snakes emerge remarkably early in spring, often basking on sun-warmed rocks while snow still lingers nearby. Recognized by a bright orange or yellow dorsal stripe running down the spine and lateral stripes on scale rows three and four, they thrive in grasslands, wet meadows, and urban parklands. They rely on keen vision to hunt amphibians, earthworms, and fish, playing a vital role in balancing local prairie food webs.
