[2] Crotaphytus reticulatus is a tan to brown lizard with reticulations covering most of its dorsum, limbs, and tail.

Unlike the rest of the species in the genus Crotaphytus, there is no color difference between males and females of C. reticulatus except during the breeding season.

Collared lizards have small pockets at the base of the tail and folds of skin above the front legs.

It spends most of its time perched on rocks, basking in the sun, but is generally quick to flee if approached.

[2] The geographic range of the species C. reticulatus is declining due to habitat destruction and possibly climate change.
