The western fence lizard, Sceloporus occidentalis, occurs throughout much of the extreme western United States. In Utah, the species can be found in the West Desert region, usually in sagebrush, grassland, or mountainous areas. It is fairly common in Utah within its range.
Female western fence lizards may lay several clutches of three to seventeen eggs during spring and early summer; eggs hatch in about two months. The diet of this lizard consists primarily of insects, such as flies and ants, and spiders. Western fence lizards are commonly called "blue-bellies" because of the blue markings on the bellies and throats of most males and some females.
