11 Types of Lizards in El Paso, Texas: A Desert Dweller’s Field Guide
October 25, 2026
Step outside almost anywhere in El Paso between spring and early fall, and there’s a good chance a lizard will dart across the trail before you even notice it. The types of lizards in El Paso, Texas range from tiny, fast-moving earless lizards to the state’s own protected horned lizard, and most of them call the rocky slopes of the Franklin Mountains and the surrounding Chihuahuan Desert home.
El Paso sits at the northern edge of the Chihuahuan Desert, in a border region that stretches from Deming and Columbus, New Mexico, in the west to Van Horn, Texas, in the east. The arbitrary geographic limits of the El Paso-Juarez border region, with El Paso-Juarez at its center, form a rectangular area bounded by Deming and Columbus, New Mexico, to the west; Radium Springs, New Mexico, to the north; and Van Horn, Texas, to the east. That mix of desert flats, rocky foothills, and river bottomland gives the area an unusually varied lizard population for a single metro region, one documented in detail by the University of Texas at El Paso’s herpetology checklist. This guide walks through 11 species you’re likely to encounter, with tips on where each one lives and how to tell it apart from its desert neighbors. For a broader look at species found across the state, the complete guide to Texas lizards covers regions well beyond the El Paso valley.

| Lesser Earless Lizard | Sandy grasslands, desert scrub | Small | Rows of dark blotches along the back |
| Texas Horned Lizard | Open desert, sparse grassland | Medium | Rows of true bony horns; flattened body |
| Mountain Short-Horned Lizard | Higher rocky slopes and canyons | Small to medium | Short, blunt horns; stockier build |
| Round-Tailed Horned Lizard | Fine sand and gravel flats | Small | Rounded tail; no head fringe of horns |
| Desert Spiny Lizard | Rock outcrops, mesquite, adobe walls | Medium to large | Large, keeled, spiny scales |
| Eastern Collared Lizard | Rocky canyons, boulder fields | Large | Bold black throat collar |
| Texas Banded Gecko | Rock crevices, under debris | Small | Smooth, soft skin; dark crossbands |
| Striped Whiptail Lizard | Grassy desert flats, wetland edges | Small to medium | Narrow, sharply defined body stripes |
| Great Plains Skink | Loose soil, grassland edges | Medium to large | Smooth, glossy scales |
| Common Side-Blotched Lizard | Almost any open desert habitat | Small | Dark blotch behind the front leg |
1. Greater Earless Lizard
The greater earless lizard (Cophosaurus texanus) is one of the most conspicuous lizards on El Paso’s rocky trails, largely because it doesn’t bother hiding when a hiker walks by. It seems to prefer the middle to higher open desert elevations, especially in rocky mountain foothills that support communities of mesquite, creosote, acacia, cacti and ocotillo plants, and it may take up a watch atop large cobbles, holding its ground to bask in the sun even as hikers pass nearby.
As its name suggests, this lizard lacks visible ear openings. Greater earless lizards do not have external ear openings, and the tail is slightly flattened and longer than the head and body combined, with the underside white and marked by 5 to 9 bold, contrasting black bands. Males take on brighter coloring during breeding season. Males grow larger and are more colorful than females, exhibiting pink and green colors that are particularly bright in the breeding season, while two bold black bars mark the lateral region of males but are greatly reduced or absent in females.
Diet-wise, this species is an opportunistic hunter. The greater earless lizard preys primarily on arthropods, including butterflies, moths, beetles, grasshoppers, stinging insects, and spiders, with the mature, larger lizard taking the larger prey and the younger, smaller lizard the smaller prey. That broad appetite for common Texas insects makes it a useful check on grasshopper and beetle numbers around the Franklin Mountains. Research from the Animal Diversity Web also notes that its digging habits help aerate desert soil for nearby cacti and shrubs.
Key Insight: Earless lizards aren’t actually deaf. They lack the visible ear opening most lizards have, but they can still detect ground vibrations and low-frequency sound, which helps them react quickly to approaching predators.
2. Lesser Earless Lizard
The lesser earless lizard (Holbrookia maculata) shares its cousin’s missing ear openings but is noticeably smaller and less bold about basking in the open. This close relative of the greater earless lizard occurs from the northern Chihuahuan and northeastern Sonoran Deserts northeastward into the Great Plains, is smaller than the greater earless lizard, bears several distinguishing rows of blotches along its back from the neck to the tail, and is usually less active during the mid-day heat.
That midday retreat pattern is a useful identification clue in the field. If a small, blotched lizard vanishes during the hottest part of the afternoon and reappears in the cooler morning and evening hours, it’s more likely a lesser earless lizard than its more heat-tolerant relative. Both species share the sandy, gravelly flats typical of El Paso’s desert lowlands, as detailed by DesertUSA’s field notes on regional earless lizards.
3. Texas Horned Lizard
No El Paso lizard carries more cultural weight than the Texas horned lizard (Phrynosoma cornutum), better known across the region as the “horny toad.” It is the largest-bodied and most widely distributed of the roughly 14 species of horned lizards in the western United States and Mexico, with an average snout-vent length of 69 mm, though the upper boundary reaches 94 mm in males and 114 mm in females.
This species has faced a well-documented decline. The Texas horned lizard was one of the first animals to be listed as a threatened species in Texas, in 1977, and it later received further recognition. The Texas horned lizard is the most widely known and most prevalent horned lizard in the state, and in 1993 was officially designated the state reptile by the Texas legislature. According to the Texas State Historical Association, protections were originally sought because of overcollection for the pet trade, and habitat loss remains an ongoing concern.
Important Note: It is illegal to collect, possess, or sell a Texas horned lizard taken from the wild. State wildlife officials encourage photographing sightings and logging them through citizen-science apps rather than handling the animals. This article is for educational identification purposes only and is not legal advice.
The horned lizard’s defenses go well beyond its rows of bony head spines:
- Squirting a thin stream of blood from the corners of its eyes when seriously threatened
- Flattening its body against the ground to blend with sand and gravel
- Puffing up to make its spines harder for a predator to grip
- Relying on harvester ants and small beetles as a primary, specialized food source
It feeds on grasshoppers, isopods, small beetles, and beetle larvae in addition to ants, a diet closely tied to the health of local beetle populations found throughout Texas. Because the species is protected, anyone drawn to horned lizards after reading about them should look into captive-bred pet reptile species rather than attempting to keep a wild-caught animal.
4. Mountain Short-Horned Lizard
The mountain short-horned lizard (Phrynosoma hernandesi) occupies higher, rockier ground than its more famous cousin, favoring the canyons and elevated slopes of the Franklin Mountains over open desert flats. It’s stockier and has shorter, blunter horns than the Texas horned lizard, and it shares the same legal protections. The mountain short-horned lizard is also protected, but the round-tail, which is rarely seen in Texas, is not.
Because this species tends toward cooler, higher elevations, it’s less likely to turn up in a backyard than the Texas horned lizard but more likely to be spotted along rocky hiking routes with some elevation gain. Its range overlaps with several other short-horned lizard populations found in neighboring Arizona, where similar rocky, mid-elevation habitat supports comparable horned lizard communities.
5. Round-Tailed Horned Lizard
The round-tailed horned lizard (Phrynosoma modestum) is the smallest and least conspicuous of the three horned lizard species documented in the El Paso area. Unlike its relatives, it lacks the pronounced fringe of horns around the back of the head, and its tail is rounded rather than flattened, which gives the species its name.
This species tends to favor fine sand and gravel flats where its pale, mottled coloring blends almost seamlessly with the substrate. It’s genuinely uncommon in Texas records overall. The round-tail is rarely seen in Texas, which makes any confirmed sighting in the El Paso area noteworthy for local naturalists. Its range extends south into arid regions of northern Mexico, where similar desert flats support the species more broadly.
6. Desert Spiny Lizard
The desert spiny lizard (Sceloporus magister) is one of the larger, more heavily armored lizards around El Paso, easily recognized by its large, keeled scales that give the skin a rough, spiky texture. It’s a confirmed member of the local herpetofauna documented on the UTEP El Paso-Juarez region checklist, which lists it alongside the area’s other spiny and fence lizards.
These lizards favor rocky outcrops, mesquite thickets, and even old adobe walls, where they bask on vertical surfaces and retreat into crevices when threatened. Males often display bold blue patches along the throat and belly during breeding season, a common trait across the wider spiny lizard group. Their diet leans heavily on insects and other arthropods, including many of the moth species found across Texas that are active at dusk when these lizards are still foraging.
7. Eastern Collared Lizard
Few El Paso lizards are as visually striking as the Eastern collared lizard (Crotaphytus collaris), a large, powerfully built species named for the bold dark band that wraps around its throat. A large brown lizard with a black band around its throat is easily recognized among the region’s other reptiles. The National Park Service’s Big Bend guide, describing populations found throughout the Chihuahuan Desert, notes that males in particular display brighter colors during the breeding season, a pattern also documented in El Paso-area sightings.
Pro Tip: Eastern collared lizards are strong runners that can briefly rise onto their hind legs when sprinting across open ground. Boulder fields and rocky canyon rims near the Franklin Mountains are among the best places to spot this behavior firsthand.
This species is a capable predator itself, feeding on insects, smaller lizards, and even the occasional whiptail lizard when the opportunity arises. Their bold coloring and defensive posturing make them one of the more memorable sightings for visitors exploring rocky trails, and their presence has been recorded at multiple sites around the region, including trails highlighted by the National Park Service’s Big Bend lizard guide.
8. Texas Banded Gecko
Unlike most El Paso lizards, the Texas banded gecko (Coleonyx brevis) is almost never seen basking in daylight. This small, soft-skinned gecko is nocturnal, spending daylight hours tucked beneath rocks, bark, or debris and emerging after dark to hunt insects. Texas has two native species of geckos, the Texas banded gecko and the reticulated gecko.
Its smooth, almost translucent skin and dark crossbands set it apart immediately from the region’s rougher-scaled diurnal lizards. If a gecko turns up under a porch light or patio stone in El Paso, it’s most often either this native species or an introduced Mediterranean gecko. Both are totally harmless, so if a homeowner finds one, the best approach is simply to leave it alone. For anyone curious how this species compares to its relatives statewide, the full rundown of Texas gecko species covers the differences in detail, as does the Chihuahuan Desert Education Coalition’s gecko profile.
9. Striped Whiptail Lizard
Fast, slender, and almost always in motion, striped whiptail lizards (Aspidoscelis inornata) are among the trickiest El Paso lizards to get a clear look at. Their narrow body stripes run the length of the torso, and they forage constantly by poking their snouts into leaf litter and loose soil in search of insects and spiders.
Local wetland habitat supports whiptail activity alongside other reptile species. Documentation from the Rio Bosque Wetlands Park in El Paso notes the presence of whiptail lizard populations displaying the rapid, darting movement typical of the group. Because whiptails rarely pause for long, patient observers near grassy desert edges or wetland margins have the best odds of a confirmed sighting. Their diet overlaps with several common desert insects, including many beetle species documented across Texas.
10. Great Plains Skink
The Great Plains skink (Plestiodon obsoletus) stands out from El Paso’s other lizards thanks to its smooth, glossy scales, which give it a distinctly different texture from the region’s spiny or granular-skinned species. It belongs to the skink family found throughout Texas. The species is classified within the family Scincidae and holds an IUCN status of Least Concern.
This is a secretive lizard that spends much of its time under rocks, logs, and loose soil, only emerging to hunt insects, spiders, and smaller lizards. Recent sightings confirm the species remains active in urban El Paso as well as its wilder outskirts. Observations of the Great Plains skink have been logged from locations along Jon Cunningham Blvd in El Paso. Its range extends well beyond West Texas, overlapping with skink populations found across much of the eastern half of the country, including the lizard species documented in Tennessee.
11. Common Side-Blotched Lizard
The common side-blotched lizard (Uta stansburiana) may be the single most frequently encountered lizard in El Paso, showing up in backyards, vacant lots, and desert trails alike. It’s small, quick, and identified by the dark blotch just behind each front leg that gives the species its name.
Recent citizen-science records confirm just how widespread this species has become across the city. A common side-blotched lizard was documented in West Central El Paso in a residential neighborhood setting. That kind of adaptability to disturbed, developed land is part of why the species thrives even as desert habitat around El Paso continues to shift with urban growth. Anyone comparing notes across state lines will find a similarly adaptable lizard fauna in the guide to Arizona’s native lizard species, many of which share overlapping ranges with El Paso’s desert populations.
Together, these 11 species show just how much diversity a single desert city can support, from a state-protected horned lizard living alongside backyard side-blotched lizards to nocturnal geckos most residents never see. Anyone spending time on Franklin Mountains trails, at Hueco Tanks, or even in a quiet backyard has a real chance of spotting several of these species in a single season. Logging sightings through citizen-science platforms not only helps confirm which species remain common but also supports the ongoing conservation work protecting El Paso’s more vulnerable lizards, particularly the Texas horned lizard, for future generations.
