The western banded gecko, Coleonyx variegatus, occurs throughout the southwestern United States and northern Mexico. In Utah, the species can be found in the Mojave Desert of the extreme southwestern part of the state.
The western banded gecko eats small invertebrates, primarily insects and spiders. Females may lay several clutches of eggs each year during the spring and summer. The average clutch size is two eggs, and eggs hatch in about six weeks. Western banded geckos are excellent climbers that can be found in many types of habitat. Members of the species are nocturnal and become inactive during the day, as well as during the very cold and very hot times of the year.
