The third eye (the parietal eye) is easily located in the center of this scale. The dorsal ground color of Side-blotched Lizards is generally a light shade of gray or tan that is sprinkled with both light and dark colored spots. Some of these spots may be light blue on both sexes, and males often have orange sides and neck, particularly during the breeding season. The ventral coloration of Side-blotched Lizards is more subdued, being a light cream or white. The most obvious marking is the namesake of these lizards, and is the dark bluish-black spot that is present on the sides behind the forelimbs. These spots are more distinct in males, but females and juveniles generally have the marking to some degree. Overall, females and juveniles are less vividly colored than their male counterparts.
