Females have a white belly and a white, orange or yellow throat.

Habitat: Tree lizards are found in desert habitats with or without trees, which include mesquite, tamarisk, oaks and cottonwoods, and are often seen on buildings and fence posts. They are especially attracted to the edges of rivers, streams and washes. This tree lizard subspecies is more often found on rocks than on trees due to the rugged and treeless mountainous terrain that makes up much of their range.
