They are similar in appearance to the western fence lizard, just smaller with more scales.

These lizards are brown, gray, or olive in color with blue or green on the surface. It’s not uncommon for these reptiles to have an irregular pattern on the tail and body. They have a black bar that runs on the shoulders with lighter lines on both sides.

Females tend to have a yellow or white belly, while males have blue patches on their throats and bellies. Males develop orange coloration during the breeding season.

These lizards are usually found in a host of habitats from forests to woodlands to shrubland. They enjoy laying in the sun and basking on rocky outcrops and logs.

When scared, they will reach for rocks, trees, or crevices in order to hide. They tend to brumate (hibernate) in the winter months.

Side-blotched lizard

Scientific name: Uta stansburiana.

These lizards are small lizards with males only growing up to 2.4 inches (6cm) from snout to vent.

Males are aggressive and very defensive of their territory.

Tail length plays a role in the dominance hierarchy within this species. A reduction in tail size in males and females will be a loss of social status.

The bright blue belly is what really sets these lizards apart. They have yellow in the ventral side of the limbs with blue patched throats.

Females are not as bright in color, neither are juveniles. Males can display a bright turquoise blue color with some spots on the surface.

These lizards enjoy a host of habitats and can be found in sagebrush, woodland, farmland, grasslands, and more. They do avoid a harsh desert environment and prefer being close to water. They are often seen lying on the paths and rocks, even fence posts soaking up the sun.

They change their color from a tan or light gray to black, which helps them absorb the sun’s UV rays with ease.
