Side-blotched Lizards

General Biology: These lizards are between 2-3 inches long and are tan, brown, or gray with a mottling of black, brown, and additional light-colored markings on its dorsal (back) surface. These lizards blend in very well to their environment and are often not seen until they dart across the ground. These small lizards have a gular fold, a flap of skin that can be inflated in mating or territorial displays. The mature males of this species have small light blue spots on their backs and an orange tinge to their neck, forelimbs, sides, and tails.

Behavior: These lizards are often seen on the ground at the edge or under shrubs or other vegetation that provides cover from larger predators. During the heat of the day, rainy periods, or cooler periods, they retreat underground or move under cover such as rocks, trees, or other woody debris.

Conservation: The Side-blotched lizard is moderately sensitive to climate changes. Their habitat, the shrub-steppe, are sensitive to altered fire patterns as well as invasive weeds such as cheatgrass. The disappearance of their habitat as well as warmer temperatures could cause disruptions to their breeding cycles as well as regulating their temperatures, leading to a decrease in the lizard population.

When to See: Often seen at Bryce Canyon during the summer, the Side-blotched lizard emerges around April and will retreat from the cooler weather in September or October. They are most active during the spring and fall and tend to hide from the heat during hot summer days.
