Different Types of Lizards Found in Arkansas

Eastern Fence Lizard (Sceloporus undulatus)

The Eastern Fence Lizard is one of the most recognizable lizards in Arkansas, easily identified by its rough, spiny scales and mottled gray-brown coloration. Males often show blue patches on the throat and belly, especially during the breeding season, making them stand out against the woodland floors. Their triangular heads and keeled scales give them a rugged, textured appearance that helps them blend into tree bark and rocky surfaces.

This species usually measures between 4 and 7 inches in total length, with slender bodies and long tails that aid in quick movement. Their size and coloration vary slightly depending on habitat, but juveniles tend to appear darker with faint crossbands. These lizards are agile climbers that can quickly dart up trees when disturbed, using their sharp claws to grip rough surfaces.

Eastern Fence Lizards are active during the day and rely heavily on basking to regulate their body temperature. They are wary and will run when approached, freezing on tree trunks to rely on camouflage. Their behavior includes short bursts of sprinting, push-up displays by males, and quick dashes after prey, showcasing their energetic lifestyle.

They prefer dry, open woodlands, forest edges, and areas with abundant logs, fences, or rocks for basking. In Arkansas, they are widespread throughout the state. Their diet consists mainly of insects such as ants, beetles, spiders, and small arthropods. They play an important role in controlling insect populations across their habitats.

Texas Horned Lizard (Phrynosoma cornutum)

The Texas Horned Lizard is a striking species known for its flattened body, crown-like head spines, and short, rounded tail. Its sandy, brownish coloration allows it to blend perfectly into arid environments. The body is covered with sharp scales and horns, giving this species a prehistoric appearance unlike any other lizard in Arkansas.

Adults typically range from 3.5 to 5 inches long, with a broad, oval body and squat legs. The horns on the head are true bone extensions, offering protection from predators. Despite their intimidating appearance, they are gentle and slow-moving lizards that depend heavily on camouflage as their primary defense.

These lizards exhibit fascinating behaviors, including the ability to puff up their bodies to appear larger when threatened. In extreme situations, they can even squirt blood from their eyes as a last-resort defense mechanism. Most of their time is spent basking, resting, or quietly hunting ants—their preferred food source.

In Arkansas, the Texas Horned Lizard is considered rare and has experienced significant population declines due to habitat loss and fire ant invasion. They inhabit open sandy prairies, grasslands, and sparsely vegetated areas. Their diet is dominated by harvester ants, though they also consume beetles and other small invertebrates. Conservation protections are crucial for the survival of this unique species.

Mediterranean House Gecko (Hemidactylus turcicus)

The Mediterranean House Gecko is a small, pale nocturnal lizard easily recognized by its translucent skin, large lidless eyes, and sticky toe pads. Their bodies are typically light tan or pinkish with dark mottling, giving them a speckled appearance under artificial light. They are common around human structures, where they cling to walls and ceilings in search of insects.

Adults usually measure between 4 and 5.5 inches long, with slender bodies and semi-transparent tails. Their skin has a slightly warty texture, and the large golden eyes help them see well at night. When threatened, they can drop their tail, which continues to wiggle as a distraction while the gecko escapes.

Mediterranean House Geckos are active primarily at night and frequently congregate near porch lights, windows, and street lamps where insects gather. They are quiet, secretive, and quick, often darting into cracks or behind outdoor fixtures. Their chirping sounds, produced by males, are commonly heard during warm months.

This species thrives in warm, urbanized areas across Arkansas, especially in the southern and central regions. They inhabit houses, garages, brick buildings, and any location with access to insects. Their diet consists of moths, flies, spiders, beetles, and small nocturnal arthropods, making them beneficial neighbors that help reduce pest populations.

Six-lined Racerunner (Aspidoscelis sexlineatus)

The Six-lined Racerunner is one of Arkansas’s fastest lizards, known for its sleek body and six bright yellow or greenish stripes that run from head to tail. The dark background color highlights the stripes, creating a vivid contrast that makes the species easy to identify. Males often show hints of blue on the throat and belly during the breeding season.

This species grows between 6 and 9.5 inches long, including the tail, which can make up more than half its total length. Racerunners have extremely long limbs and tails, built for rapid movement across open terrain. Their smooth scales and streamlined shape reduce drag and help them achieve impressive speeds.

Six-lined Racerunners are highly active during the hottest parts of the day, often seen sprinting across sandy paths, grasslands, and open fields. Their behavior is energetic and alert, rarely staying still for more than a few moments. When threatened, they rely on speed rather than camouflage to escape predators.

They inhabit open sandy soils, prairies, rocky glades, and woodland edges throughout Arkansas. These lizards prefer sunny environments with sparse vegetation and plenty of room to run. Their diet includes grasshoppers, beetles, ants, spiders, and other fast-moving insects. Their presence contributes significantly to controlling insect populations in open habitats.

Little Brown Skink (Scincella lateralis)

The Little Brown Skink is a small, smooth-scaled lizard with a slender body and glossy bronze or chocolate-brown coloration. Its long tail, which is twice the length of its body, gives it a sleek appearance. A thin dark stripe runs down each side of the body from snout to tail, making it easy to distinguish from other Arkansas skinks.

This species averages only 3 to 5.5 inches in total length, making it one of the smallest lizards in the state. Its tiny limbs and narrow body allow it to move easily through leaf litter and loose soil. Because of its diminutive size, it is often overlooked even in areas where it is abundant.

Little Brown Skinks are secretive and spend much of their time hidden under leaves, logs, and loose debris. They are active during the day but remain close to the ground, quickly wriggling away when disturbed. Their behavior resembles that of a small snake when they move through leaf litter, with rapid, serpentine motions.

These skinks inhabit moist woodlands, forest floors, and shaded areas throughout Arkansas. They prefer environments with deep leaf litter and loose soil for burrowing. Their diet consists of small insects, spiders, larvae, and soft-bodied invertebrates found among decaying plant material. They help maintain healthy forest ecosystems by controlling decomposer-associated insect populations.

Five-lined Skink (Plestiodon fasciatus)

The Five-lined Skink is one of the most familiar lizards in Arkansas, easily recognized by its shiny body and five bold stripes running from the head down the tail. Juveniles are especially striking, with bright blue tails and crisp yellow or white stripes. Adults often lose some of the contrast in their stripes, and males may develop an orange-red coloration on the jaw during the breeding season.

This species typically reaches 5 to 8.5 inches in total length, with smooth scales that give the body a polished appearance. The sleek form and moderately long tail help the skink move quickly through vegetation and leaf litter. Males tend to be slightly larger and bulkier, with broader heads than females.

Five-lined Skinks are diurnal and active, frequently seen basking on logs, tree trunks, and sunlit rocks. They are agile climbers and quick runners, often darting out of sight when approached. Their behaviors include foraging for insects, displaying territoriality, and hiding in crevices to avoid predators.

Broad-headed Skink (Plestiodon laticeps)

The Broad-headed Skink is a large, muscular lizard known for its wide head and powerful jaws. Males are particularly distinctive, often showing bright orange or red coloration on the head during the breeding season. Juveniles resemble Five-lined Skinks, displaying five stripes and a brilliant blue tail, but they grow into much larger and more robust adults.

This species is the largest skink in Arkansas, commonly reaching 6 to 13 inches in total length. The head becomes noticeably broad in mature males, and their bodies develop a strong, sturdy appearance. Adults often lose their stripes, becoming more uniformly olive, brown, or gray in coloration.

Broad-headed Skinks are excellent climbers that spend much of their time in trees, more so than most other skink species in the state. Their behavior includes sunbathing on branches, aggressively defending territories, and quickly scaling tree trunks when alarmed. Although wary, they will stand their ground if cornered.

They inhabit mature forests, wooded swamps, and areas with abundant tree cover across much of Arkansas, though they are more common in the southern half of the state. Their diet includes insects, spiders, snails, small frogs, and other invertebrates. As one of the top reptile predators in forest ecosystems, they help maintain ecological balance.

Prairie Skink (Plestiodon septentrionalis)

The Prairie Skink is a slender, smooth-scaled species characterized by its tan or brown body with two light stripes running along each side. Unlike the Five-lined Skink, its stripes do not extend down the back, giving it a more subtle appearance. The overall coloration helps it blend seamlessly with dry grasses and sandy soils.

Adults typically measure 5 to 8 inches in length, with long tails that can comprise more than half their total size. Their scales are glossy, and the body is well-suited for rapid movement through loose soil. Males may develop orange or reddish coloration along the jaw during the breeding season.

Prairie Skinks are active, ground-dwelling lizards that spend much of their time hiding beneath rocks, logs, or tall grass. They are quick, secretive, and immediately flee when disturbed. Their behaviors include burrowing into loose sand, basking near grass clumps, and foraging during warm daylight hours.

In Arkansas, Prairie Skinks are limited mainly to the northern and western regions where open prairies, sandy fields, and dry grasslands are present. Their diet consists of grasshoppers, beetles, crickets, spiders, and soft-bodied insects. They are valuable predators in open habitats, helping control insect communities in prairie ecosystems.

Ground Skink (Scincella lateralis)

The Ground Skink, also called the Little Brown Skink, is a small, slender lizard with a shiny brown or bronze body and a long, narrow tail. A dark line runs along each side of the body, giving it a simple but distinctive appearance. Because of its size and coloration, it often goes unnoticed on the forest floor.

This species grows only 3 to 5.5 inches long, making it one of the smallest lizards in Arkansas. The smooth scales allow the skink to glide easily through leaf litter, and its tiny legs help it maneuver beneath debris. The tail is delicate and can break off easily as a defense mechanism.

Ground Skinks are secretive and spend most of their time under leaves, logs, and loose soil. Their movements are serpentine and rapid, often resembling a small snake when they dart away. They remain close to the ground, preferring to forage and bask in low, sheltered areas rather than climbing.

They inhabit moist forests, shaded woodlands, and areas with deep leaf layers across Arkansas. Their diet includes ants, spiders, small beetles, insect larvae, and other tiny invertebrates. By consuming soil-dwelling insects, Ground Skinks contribute to decomposition processes and overall forest health.

Coal Skink (Plestiodon anthracinus)

The Coal Skink is a dark, sleek lizard recognized by its rich black or chocolate-brown body and strongly defined stripes. Two pale stripes run down each side of the body, bordered by darker pigment that gives the species a bold, contrasting look. Its coloration is deeper and more uniform than that of similar skinks in the region.

Coal Skinks typically measure 5 to 7 inches in total length, with narrow bodies and smooth, shiny scales. Their heads are small and delicate, blending smoothly into the neck and body. The tail is long and slender, helping with quick bursts of movement across the forest floor.

This species is secretive and difficult to spot, spending much of its time hiding beneath rocks, logs, and wet leaf litter. When threatened, it moves quickly and attempts to slip into crevices or underground burrows. Coal Skinks prefer cool, moist environments and are less tolerant of dry, exposed habitats than other skinks.

In Arkansas, they are found mostly in the Ozarks, Ouachitas, and other forested, rocky regions with reliable moisture. Their diet consists of small insects, spiders, crickets, and soft-bodied invertebrates. Coal Skinks help regulate insect populations in cool forest ecosystems and are indicators of healthy, moist woodland environments.

Common House Gecko (Hemidactylus frenatus)

The Common House Gecko is a small, pale gecko known for its translucent skin, soft pink or gray coloration, and large lidless eyes. Its toes have expanded pads that allow it to cling effortlessly to smooth surfaces. Under artificial light, its mottled pattern becomes more visible, helping distinguish it from other urban gecko species.

Adults typically range from 3.5 to 5.5 inches long, including the tail. Their bodies are slender and slightly warty, and they can regenerate lost tails if threatened. The tail may appear slightly banded in juveniles, and the skin can look almost transparent when illuminated. These geckos are lightweight and extremely agile climbers.

Their presence helps reduce pest populations in residential areas.

Slender Glass Lizard (Ophisaurus attenuatus)

The Slender Glass Lizard is one of Arkansas’s most distinctive reptiles, easily recognized by its long, legless body that resembles a snake. Unlike snakes, however, it has external ear openings and movable eyelids. Its tan or brown coloration with dark stripes and speckling makes it blend well with grassy habitats.

This species typically grows 22 to 42 inches long, making it one of the longest lizards in North America. The body is rigid and fragile, capable of breaking into multiple segments if the tail is shed. Despite their appearance, Glass Lizards have a stiff, solid body unlike the flexible form of snakes.

Slender Glass Lizards are secretive, spending much of their time hidden in tall grass, under debris, or in sandy soils. They move with quick lateral motions but cannot coil or lift the body like snakes. Their behaviors include rapid foraging, tail autotomy, and freezing when threatened.

They inhabit grasslands, open woodlands, and sandy fields across much of Arkansas, especially in the central and southern regions. Their diet consists of insects, spiders, small rodents, eggs, and other invertebrates. As important predators in grassland ecosystems, they help balance invertebrate populations.

Western Worm Snake-like Lizard (Ophisaurus attenuatus)

This name refers to worm-like color forms of the Slender Glass Lizard that appear more uniformly brown or gray, lacking the stronger striping seen in typical individuals. These variations can make the lizard resemble a large, glossy earthworm or small snake. The smooth, shiny scales enhance the worm-like appearance.

Individuals in this form usually share the same size range as standard Slender Glass Lizards, commonly reaching 22 to 40 inches long. Their bodies are stiff, and the tail makes up a large portion of their total length. These variants may show faint lateral lines but generally lack strong dorsal patterns.

Behavior is similar to other glass lizards, with individuals spending most of their time underground or within dense leaf litter. They prefer to avoid sunlight and quickly burrow when disturbed. Their movements are rapid but restricted by their stiff bodies, creating a unique gliding motion across the ground.

These worm-like glass lizards occur in scattered localities across Arkansas, especially in sandy or loamy soils that allow easy burrowing. Their diet includes beetles, caterpillars, spiders, slugs, and soft-bodied prey. Although visually distinct, they remain part of the broader Slender Glass Lizard population.

Southern Prairie Lizard (Sceloporus consobrinus)

The Southern Prairie Lizard is a small, spiny-scaled lizard resembling the Eastern Fence Lizard but with subtler coloration and more uniform patterns. Its body is typically gray or light brown with faint crossbands and rough scales. Males often show blue patches on the throat and belly during breeding season.

This species usually grows 4 to 6 inches long, with a sturdy body and proportionate limbs. The keeled scales give the lizard a rough texture, helping it blend with bark, rocks, and soil. Juveniles tend to appear darker and more patterned than adults, aiding in camouflage.

These lizards are diurnal and highly active, commonly seen basking on logs, fences, and rocks. They rely on short bursts of speed to escape predators and often freeze against tree trunks to blend in. Their behaviors include territorial displays, insect hunting, and rapid climbing when alarmed.

Southern Prairie Lizards inhabit dry forests, open glades, grasslands, and rural areas throughout much of Arkansas. They prefer sunny habitats with scattered vegetation. Their diet consists of ants, beetles, spiders, and various arthropods. They are important insect predators in prairie and woodland-edge ecosystems.

Great Plains Skink (Plestiodon obsoletus)

The Great Plains Skink is a large, impressive lizard recognized by its mosaic-like pattern of black-edged scales and muted brown or tan coloration. Its body appears slightly rough but still glossy, creating a distinctive checkered look. The tail and body often shift from light brown to darker tones toward the back.

Adults can reach 9 to 13 inches in total length, making them one of the largest skinks in the region. Their bodies are thick and muscular, with smooth scales that create a sleek, streamlined appearance. Juveniles are darker and may show a blue-tinted tail before growing into adult coloration.

Great Plains Skinks are ground-dwelling and prefer to stay near cover such as rocks, logs, and burrows. They are secretive but strong, capable of fast bursts of movement when threatened. Their behaviors include digging, hiding in crevices, and foraging during the warmer hours of the day.

In Arkansas, this species is considered occasional or rare, typically appearing in western or northwestern counties near open prairies, rocky hillsides, and semi-arid habitats. Their diet includes large insects, spiders, beetles, and sometimes small vertebrates. They contribute to controlling insect populations in open and dry habitats.

Speckled Racer (Drymobius margaritiferus)

Although technically a snake rather than a lizard, the Speckled Racer occasionally appears as a rare stray in southernmost Arkansas. It is easily recognized by its striking pattern of black scales speckled with bright bluish-green spots. The slender body and smooth scales give it a glossy, iridescent look.

This species typically reaches 30 to 40 inches in length, with a long, agile form built for speed. The head is narrow, and the eyes are large, contributing to excellent vision. Its scales create a shimmering effect in sunlight, making it one of the visually most beautiful snakes in North America.

Speckled Racers are fast, active hunters that move quickly through grass, wetlands, and shrublands. They rarely remain still, using their speed to chase down prey. Their behaviors include rapid fleeing, active pursuit of frogs and lizards, and constant patrolling through vegetation.

In Arkansas, this species is extremely rare and usually appears only as a southern wanderer. It prefers warm, humid habitats such as marsh edges, forests, and riparian zones. Its diet includes frogs, lizards, small snakes, and insects. Due to its rarity, it is not considered part of Arkansas’s stable resident fauna.

Best Time and Places to Observe Lizards in Arkansas

The best time to observe lizards in Arkansas is during the warmer months, especially from late spring through early fall when temperatures reach their peak. Most species are active during the day and spend the early morning and late afternoon basking on rocks, logs, and warm ground surfaces. Midday activity is common in heat-tolerant species such as the Six-lined Racerunner, while nocturnal geckos are easiest to spot around artificial lights at night.

Woodlands, open prairies, rocky glades, and forest edges offer the best chances to see native species. Areas with plenty of fallen logs, tree trunks, or sunlit clearings often support Five-lined Skinks and Southern Prairie Lizards. Sandy fields and grasslands are prime territory for Prairie Skinks and Racerunners, which prefer open ground and warm, dry conditions. Moist forest floors rich in leaf litter provide excellent habitat for Ground Skinks and Coal Skinks, especially in the Ozark and Ouachita regions.

Urban and suburban locations can also be productive, particularly for gecko species such as the Mediterranean House Gecko and the localized Common House Gecko. These lizards thrive around houses, streetlamps, brick walls, and warm building exteriors where insects gather at night. Occasional species like the Texas Horned Lizard or Great Plains Skink are more secretive and far less common, requiring visits to specific prairies or semi-open habitats for a chance encounter.

For the best overall experience, early summer evenings and warm mornings provide the highest lizard activity in most parts of the state. Observers should move quietly, scan sunny surfaces carefully, and be patient, as many species rely heavily on camouflage. Using binoculars, wearing neutral clothing, and exploring slowly increases the likelihood of spotting Arkansas’s diverse reptile species.
