The Eastern Fence Lizard (scientific name: Sceloporus undulatus), also referred to as the Northern Fence Lizard or the Prairie Lizard, is a species of lizard found primarily in the eastern United States. This small to medium-sized reptile typically measures between 5 to 7 inches in length, with the male individuals usually being larger than the females.
The Eastern Fence Lizard is characterized by its distinct coloration and pattern. Its overall body color varies, ranging from gray to brown, while its dorsal side is marked with dark brown or black patches often forming a series of interconnecting bands. The lizard's back also possesses a series of light-colored, wavy crossbars or "fence-like" patterns, which give it its common names. Moreover, the species has rough scales and slightly spiny projections along its back.
This reptile is commonly found in woodland areas, as well as open fields, meadows, and rocky outcrops, where it basks in the sun on fence posts, tree trunks, or rocks. It is known to be an adept climber, often seen ascending trees and shrubs to capture insects, spiders, and other small invertebrates.
As a defense mechanism, the Eastern Fence Lizard is capable of performing an impressive "push-up" display to deter predators. It extends and raises its body while simultaneously lowering its head to display its brightly colored throat. This behavior is especially prominent during territorial interactions with other males or when confronted by potential threats.
In summary, the Eastern Fence Lizard is a native reptile of the eastern United States, recognized for its unique coloration and pattern. It is commonly found in woodland habitats, and its diet mainly consists of insects and other arthropods.
