How to identify it
Relatively large, long-legged lizard (snout-vent 65-93 mm) with a flattened tail and long hind limbs. [1][2]
Grey to brown back with yellow blotches and dark spots on both sides of the mid-dorsal line. [1][2]
Tail and limbs have 4-8 dark cross bands, and the tail underside is boldly black and white striped. [1][2]
Both sexes have a dark throat with radiating black lines; males also have sky to navy blue patches on each side of the belly, which females lack. [1][2]
Males show metallic green-blue (sometimes orange and yellow) on the sides in breeding season. [1][2]
Where it lives
Open, sparsely vegetated desert with loose sandy soil: washes, dunes, floodplains and desert pavement, often among shrubs. [1][2]
How it behaves
Diurnal and heat-tolerant: often basks and is active in midday heat when other lizards shelter; most active about 0900-1300 in Nevada. [1][2]
Wags and curls the black-and-white tail as a display to other lizards and when a predator is near. [1][2]
Active in warm months and hibernates roughly October to April; digs burrows, usually under shrubs, for shelter and night retreats. [1][2]
Eats mostly small invertebrates (ants, flies, spiders, scorpions), plus some plant material. [1][2]
