Zebra-tailed Lizard
(Callisaurus draconoides)

Zebra-tailed LizardThese medium sized lizards are the speed demons of the desert. They have a slim body, a black and white striped tail, and slender legs. They are usually found in dry washes or other open areas that have lots of room to run. They feeds on grasshoppers, beetles, caterpillars, and flies. When approached they will sometimes wave their zebra striped tail in the air and then speed off to the nearest bush or rodent burrow for cover.  The males are larger and more brightly colored than the females.
