The Allure of the Eastern Garter Snake: Unveiling the Fascinating World of a Colorful and Adaptable Serpent
Thamnophis sirtalis
Description: The eastern garter snake has a variable color pattern, but may be identified by a yellow or white stripe running down the middle of its dark back—resembling the “garters” used to hold up socks. On its side, the garter snake usually has a checkerboard pattern of dark squares and stripes. It will often have two rows of black spots running the length of its greenish or yellowish belly. Garter snakes have rough (keeled) scales. They may be distinguished from their cousins, the ribbon snakes, by the presence of dark bars between their lip (labial) scales.
Feeding/Diet: They are most active during the day and feed mostly on frogs, salamanders, fish, and earthworms.
Habitat/Range: Eastern garter snakes are found throughout most of the United States and are one of the most wide-ranging species of snakes in all of North America. Garter snakes usually live in or near wet areas, but can be found in nearly any habitat in North Carolina.
Reproduction: They mate in the spring and in late summer and give live birth to 7–85 young.
Miscellaneous: Garter snakes may bite when handled. Like their relatives the watersnakes, garter snakes will often thrash around when picked up and expel a strong-smelling musk from scent glands at the base of the tail.
