Behavior: This is an alert, diurnal, fast-moving ground-dweller. It is an extremely active lizard that spends nearly all of its waking hours in motion foraging and moving between sun and shade for thermoregulation.
Hibernation: It hibernates during the cold months of fall and winter.
Reproduction: All Plateau Striped Whiptails are female (parthenogenetic). Eggs are unfertilized and hatchlings are clones of the mother. Three to 5 eggs are laid in June or July. Hatchlings begin to appear in August.
Diet: This lizard actively forages by rooting around in organic matter under bushes and by digging in the soil around the bases of rocks, logs, and other surface debris. It has also been observed to forage in low shrubs off the ground. It feeds on a variety of insects and spiders.
