The Great Basin collared lizard, Crotaphytus bicinctores, occurs throughout much of the western United States. In Utah, the species occurs in the western half of the state, in dry rocky areas with sparse vegetation.

The Great Basin collared lizard eats lizards, insects, spiders, and some plant material. Females lay one or two clutches of three to eight eggs each year. Eggs are laid in sandy soils or rodent burrows during June, and hatch in about three months. Like many other Utah reptiles, the Great Basin collared lizard is active only during the spring, summer, and fall, becoming inactive during the cold winter months.
