Plateau fence lizard

The plateau fence lizard (Sceloporus tristichus) is a species of spiny lizard in the family Phrynosomatidae.

Description
At up to 80 mm from snout to vent, the plateau fence lizard is a grayish, brownish, or greenish lizard. The upper side of its body has keeled scales and there is a series of narrow dark brown cross-bands on both sides of the midline. An elongated metallic blue patch can be found on each side of the belly and each side of the throat.

Males are typically smaller than females, as with many squamates, with males and females in Montezuma County, Colorado measuring 63 mm and 67 mm, respectively.

Distribution
The plateau fence lizard is generally found in central Arizona, southwestern Utah, western Colorado, and the San Luis Valley. It can also be found in parts of New Mexico and Wyoming.

Habitat
The plateau fence lizard generally dwells in rocky and wooded areas, making use of canyon walls, boulder-strewn hillsides, fallen tree trunks, and other debris and vantage points.

Ecology
The plateau fence lizard is inactive during cold periods and the hottest part of the day in summer.

The lizard consumes mainly insects, spiders, and other arthropods.
