Its lack of distinct dorsal markings (in adult males), distinguishes this lizard from the similar Desert Spiny Lizard. Their prey of insects, includes, ants, beetles and caterpillars. Desert spiny lizard is a species of lizard found in the Sonoran Desert and Chihuahuan Desert of North America. “Desert Spiny Lizard.” Arizona-Sonora Desert Museum.
It is often encountered in male-female pairs. Mating takes place in spring and summer and one or two clutches of eggs are laid in spring and summer.
Both sexes have brownish/yellow triangular spots on their shoulders.
Spiny lizards come in a variety of colors and hues. UA researcher John Wiens talks about lizards' trick tails, their propensity for pushups and more. Some species of lizards, including the Sonoran spotted whiptail and about half a dozen other whiptail species in Arizona, have evolved to be asexual.
Hatchlings may appear as early as late May but usually begin to emerge in July.
Sceloporus magister uniformis was elevated to species status in 2006 (Sceloporus uniformis), when genetic analysis revealed that it is sufficiently distinct to merit classification as its own species..
Attracted to insects around lights at night, they are the ones you may have spotted in silhouette on your windows, thanks to their sticky feet. Both sexes have brownish/yellow triangular spots on their shoulders. The Desert Spiny Lizard ranges across the deserts of southwestern Arizona and the northeastern plateaus at elevations ranging from near sea level along the Colorado River to about 5,000'.
The Desert Spiny Lizard (S. magister) is very similar to the Twin-spotted Spiny Lizard, and for many years the latter was considered a subspecies of the former.
Like many desert lizards, desert spiny lizards adjust their internal temperature by changing color so they are darker during cool times, which allows them to absorb more heat from the sun, and become lighter during warm times so they reflect more solar radiation. Craig Ivanyi.
These lizards are mostly pugnacious in nature.
In the United States it is found in the states of Arizona, California, Texas, New Mexico, Nevada, and Utah.
Copyright Qries 2018. Science Reference Center. These unwieldy and sluggish reptiles find safety in the desert. The only character that distinguishes the two is that instead of rows of dark paravertebral spots, adult male Desert Spiny Lizards have a dark or purple mid-dorsal stripe 4-5 scales wide.
Desert Spiny Lizard (Sceloporus Magister) - Reptiles of Arizona. The Old Pueblo is home to roughly a dozen different species of lizards, says John Wiens, a University of Arizona professor of ecology and evolutionary biology who studies reptiles and amphibians. S. magister, primarily an inhabitant of desertscrub and thornscrub, is found mainly on the ground in rocks and, less frequently, in trees. As they do pushups, they show off bright blue patches on their bellies, and throat patches that can be blue, green, red, yellow or orange.
These two species are insectivorous. I was surprised when we moved to southern Arizona, nearly a decade ago, by the number and variety of lizards that I encountered.
Both species have a dark collar under or around the neck; males have vivid blue throats and under-bellies.
The image reveals details that I’ve never previously been able to capture, including the very subtle colors around the lizard’s eye.

These lizards are supposed to have a high level of intelligence, a fact that their brain size substantiates. Science Reference Center). The species is diurnal and is known to form groups. Lizards enjoy sunny days and are most active in Tucson during the warmer months. Besides their bright colors, the desert spiny lizard changes to darker colors during the winter to allow them to absorb more heat from the sun, and become lighter during the summer to reflect the sun's radiation.
Sceloporus magister is the scientific name of desert spiny lizard, which is mostly found in the Chihuahuan Desert and Sonoran Desert of North America. It also feed on spiders, cetiedes, small lizards and plant material. Brennan, Thomas C. "Desert Spiny Lizard (Sceloporus Magister) - Reptiles of Arizona." Base coloration is gray, tan, or brown.
Usually, during the morning hours, it will be out basking in the sun on rocks or any hard surface that is in direct sunlight, but like many desert reptiles, it will seek shelter, usually underground in burrows or any suitable cover that provides shade, during the hottest part of the day in the summertime, as shade provides cooler temperatures than on the ground's surface. ( Log Out / On the UA campus, Wiens says, there are three main native species. If southern Arizona was not the world’s reptile capital it certainly seemed to vie for that honor. "This sort of 'fake mating' actually appears to be really important for increasing their fertility," Wiens says.
I returned to check on our friend and he was gone, evidently warmed sufficiently to become mobile.

Sceloporus magister, also known as the desert spiny lizard, is a lizard species of the family Phrynosomatidae, native to the Chihuahuan Desert and Sonoran Desert of North America. Weâre open! Tree lizards, desert spiny lizards and other members of the "iguanian" group of lizards engage in this behavior as a way to defend their territory against rival males and perhaps show off to potential mates, Wiens says. ( Log Out / No self-respecting spiny lizard would allow me to do that under normal circumstances.
These lizards change their skin color dark during winters to absorb heat while light during summers to reflect heat. To beat the summer heat, lizards generally are most active in the early morning and around sunset — like many Tucsonans. "They pretty much like the same temperatures that we do.".
Brennan, Thomas C. "Desert Spiny Lizard (Sceloporus Magister) - Reptiles of Arizona." "An optimal territory for a male overlaps the territory of a bunch of females, and that's what they're going to be fighting other males over," Wiens says. University Information Security and Privacy.
Living monuments exhibit showcases Tucson heroes in larger than life fashion. Even in the absence of males, they continue to reproduce, with the mother laying eggs that result in her exact clones, Wiens says. Males aren't always needed for reproduction.
When it is cooler, colors are much darker than when the temperature is high. Snakes: There are currently 13 recognized species of rattlesnakes in Arizona (17 in the US and about 36 species worldwide). It hibernates in late fall and during the cold months of winter before re-emerging in spring. It is frequently seen doing push-ups, pushing its body up and down, as a form of territorial display.
It also feed on spiders, cetiedes, small lizards and plant material. 23 Mar. "They've lost normal sex, but they've retained these behavioral components.".
You might have seen a lizard doing pushups in your yard, on a wall or on the side of a tree.
Besides their bright colors, the desert spiny lizard changes to darker colors during the winter to allow them to absorb more heat from the sun, and become lighter during the summer to reflect the sun's radiation. Desert Spiny Lizard …
