In the United States, C. variegatus is found in Arizona, southern California, southwestern New Mexico, Nevada, and Utah.

The western banded gecko is a terrestrial lizard, ranging in total length (including tail) from 4–6 inches (10–15 cm).

The body of the western banded gecko (excluding the tail) rarely grows past 3 inches in length.

[8] The male reptiles of this species have noticeable spurs on both sides of the body located at the base of the tail.

[6] The western banded gecko is secretive and nocturnal, with individuals remaining hidden during the day and emerging after sunset to forage for food.

Individuals prefer warm nights around 80°F, and they can often be seen near human habitations looking to make an easy meal of the insects attracted to landscape or porch lighting.

[9] C. variegatus is preyed upon by many species including coyotes, foxes, snakes, larger lizards, and even large invertebrates such as tarantulas and solpugids.
