The regal horned lizard (Phrynosoma solare) is a horned lizard species native to Mexico and the Southwest United States. The regal horned lizard is a small, flat lizard about the size of the palm of a human's hand. It has spikes all around the lateral surface of its body. It is 3–4 in (117 mm) in length from nose to tail as a full adult, and pale grey to yellow-brown or reddish in color, topped with dark blotches alongside the body and back. Its four legs each have five toes with a claw on each toe. The species is a slow runner that uses camouflage to escape predators.
This lizard can be found across southeastern Arizona and along the transition of the southern zone of the central mountains region. This horned lizard occupies primarily level or gently sloping terrain with openly spaced desert vegetation such as mesquite, creosote bush, and saguaro cactus. It can be found primarily in a hot and dry climate where the ground may be covered in limestone dust. It is found in the Sonoran Desert Mountains is where it prefers its climate, but can be found in Texas, southern California, Arizona, and New Mexico. It

Possible
About 20% of wildlife watchers report a Regal Horned Lizard sighting in Saguaro National Park on a given day, based on 144 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 11th most-seen of the 51 reptiles we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
July–August and October
In those months about 30% of wildlife watchers report a Regal Horned Lizard in Saguaro National Park on a given day, against under 5% in January, the lowest month.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Regal Horned Lizard sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Saguaro National Park, in our data
Saguaro National Park is the only park on Wallace's Line with enough records to rate Regal Horned Lizard sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Regal Horned Lizard is recorded against all the reptiles logged in Saguaro National Park (144 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
