About Sceloporus grammicus

Sceloporus grammicus, commonly known as the mesquite lizard or graphic spiny lizard, is a species of lizard native to Mexico and the southern United States, primarily in the state of Texas. It is characterized by its flat body and a tail that is slightly longer than its head and body length. Adult specimens typically range from 10 to 17.5 centimeters in total body length.

Physical Characteristics

The dorsum of Sceloporus grammicus is typically a mottled olive or gray color, featuring a pattern of three to six dark crossbars. These crossbars are also evident, though narrower, on the forelegs and tail. Males can be distinguished from females by the presence of blue patches and black mottling on their throat, a dark line on each shoulder, and blue patches on the sides of their belly, which may be bordered by black.

Reproduction and Habitat

This species is viviparous, meaning it gives birth to live young. Litter sizes can vary, with typically between 2 and 12 offspring produced. Females reach sexual maturity when their snout-to-vent length is between 34 and 74 millimeters. While specific habitat details are not extensively provided, its common name suggests an association with mesquite trees, indicating it likely inhabits arid or semi-arid environments where such vegetation is found.

Four subspecies of Sceloporus grammicus are recognized, reflecting variations across its geographic range. These include the nominate race, Sceloporus grammicus grammicus, along with Sceloporus grammicus disparilis, Sceloporus grammicus microlepidotus, and Sceloporus grammicus tamaulipensis.
