Description
Size
1 7/8 - 3 1/2 inches long from snout to vent (4.7 - 8.9 cm). (Stebbins 2003)
Appearance
A small lizard with small keeled and pointed scales overlapping on the upper surfaces of the body and limbs. These scales are not as large as they are on other lizards of the species Sceloporus. The gular fold is incomplete. The scales on the back of the thigh are mostly granular, not keeled (as they are on the Western Fence Lizard.)

Color is gray or brown with dark blotches or irregular bands on the body and tail and distinct light and dark stripes along the sides and upper sides at the edge of the back. There is usually a bar of black on the shoulder and rusy coloring on the armpits and sometimes on the sides of the body and the neck. Unlike the Western Fence Lizard - Sceloporus occidentalis, there is normally no yellow coloring on the rear of the limbs.

Males have a patch of blue color on each side of the belly and on the throat. The blue belly patches do not meet across the belly and do not meet the blue on the throat. Male postanal scales are enlarged, and the base of the tail is broader than on the female. The throat is light blue mottled with white spots. Sometimes the blue patch is reduced or even absent. Some males may develop bright orange breeding coloring.

Females have little or no blue on the belly. When breeding, females may develop orange coloring on the sides and neck and yellow underneath. Young lizards have little or no blue on the belly.
Behavior & Natural History
Diurnal. Active spring through fall. Hibernates during winter. A good climber and jumper, able to quickly jump from rock to rock. Lives mostly on the ground near bushes, logs, rocks, or brush piles. Often observed basking on rocks and logs. Escapes danger by running into rocks, rodent burrows, or brush or climbs up trees or rock outcrops.
Diet
Eats a variety of small invertebrates, including ants, termites, grasshoppers, flies, spiders, and beetles.
Reproduction
1 or 2 clutches of 2 - 10 eggs are laid from June to August.
Range
In California, occurs in the Great Basin desert east of the Sierra Nevada and in the northeast corner of the state. Ranges north into eastern Washington and east into southern Idaho, Montana, Wyoming, Nebraska, Utah, Colorado, Arizona and New Mexico.
Habitat
Lives in sagebrush and other types of shrublands, mainly in the mountains (at higher elevations than the Western Fence Lizard). Prefers open areas with scattered low bushes and lots of sun. From 500 ft. to around 10,500 ft. (150 - 3,200 m). (Stebbins 2003)
