Texas is crawling with scorpions—some are common house guests, others stick to wild desert corners.
Most folks know the striped bark scorpion, but there are at least 20 species lurking around the state.
Getting familiar with the different scorpion species in Texas isn’t just about avoiding a sting; it’s a way to appreciate these ancient, tough-as-nails critters that have figured out how to survive in all sorts of Texas landscapes.
These eight-legged hunters, with their grabby pincers and signature curled tails, mostly come out at night.
The striped bark scorpion, Centruroides vittatus, pops up in homes and yards all over central and southern Texas.
Their stings hurt—sometimes a lot—but none of the local species have venom that’s deadly to healthy adults.
Still, kids and folks with allergies should be careful and get medical help if needed.
1. Striped Bark Scorpion
The Striped Bark Scorpion (Centruroides vittatus) is probably the one you’ll see most often in Texas.
It’s yellowish-brown with two dark stripes running down its back, so it’s pretty easy to spot once you know what to look for.
Centruroides vittatus gets around—their range spreads out from Texas into nearby states and even northern Mexico.
They’re basically the “default” scorpion for much of the U.S.
Unlike some of their burrowing cousins, Striped Bark Scorpions don’t dig.
They’d rather squeeze under rocks, logs, or bark—hence the name. Grasslands and prairies are their favorite haunts.
Physical Characteristics:
- Length: 2-3 inches
- Color: Yellowish-brown with two dark stripes
- Thin pincers
- Slender tail with stinger
They’re active hunters, not the sit-and-wait type. At night, they’re out looking for insects and other small snacks, grabbing prey with their pincers before delivering a venomous sting.
Their sting is painful, but it’s usually not life-threatening for healthy adults.
Expect swelling, numbness, and some pretty intense pain. Anyone with allergies should be extra cautious.
They sneak into houses through tiny cracks, looking for cool, dark hideouts—closets, shoes, and even towels are fair game.
Female Striped Bark Scorpions do something kind of wild: after birth, they carry their babies on their backs until the little ones molt for the first time. Not something you see every day among arachnids.
2. Texas Cave Scorpion
The Texas Cave Scorpion (Pseudouroctonus reddelli) is one of two species you’ll find in Central Texas, and it’s a bit of a cave dweller.
These guys stick to cool, dark caves and rocky cracks where the sun doesn’t reach.
Compared to the Striped Bark Scorpion, the Texas Cave Scorpion is much less flashy—think brownish, no bold stripes or patterns.
Pseudouroctonus reddelli tops out at about 1-2 inches. Its pincers are pretty chunky for its body size, which makes them stand out from other local species.
Habitat & Behavior:
- Cave entrances and deep caverns
- Under rocks and logs in wooded spots
- Loves high humidity
You probably won’t find this scorpion hanging around your house.
They stick to natural hideouts, but might occasionally show up in damp, shady corners outside.
The Texas Cave Scorpion has been observed from birth to adult by enthusiasts who say they’re pretty chill compared to some other scorpions.
All scorpions have venom, but this one’s sting is about as bad as a bee sting—annoying, but not dangerous for most folks.
One interesting thing: this species glows under UV light, just like a lot of other scorpions. Biologists use this trick to spot them in the wild.
3. Big Bend Scorpion
The Big Bend Scorpion (Diplocentrus bigbendensis) is hard to miss if you’re in its territory.
Native to—you guessed it—the Big Bend region, these scorpions are known for their dark brown or black shells, which sets them apart from most other Texas species.
Adults get to be 2-3 inches long, and they’re built like little tanks: thick bodies, strong pincers, and a short tail compared to some of their relatives.
They’re part of the Diplocentridae family and are one of three big black scorpions in Big Bend, along with Diplocentrus lindo and Vaejovis intermedia.
Big Bend Scorpions stick to rocky areas with plenty of nooks and crannies.
You’ll find them under rocks, in crevices, and sometimes inside homes near their natural stomping grounds.
Behavior and Diet:
- Mostly active at night
- Eat insects, spiders, and other small critters
- Grab prey with pincers, then sting
They look pretty intimidating, but they aren’t deadly. Their sting hurts and can cause some swelling, but healthy adults rarely need a doctor.
If you’re camping or living in Big Bend country, it’s smart to check your shoes, bedding, and clothes before use.
Keeping your place tidy and clutter-free helps keep these scorpions out of your stuff.
4. Chihuahuan Scorpion
The Chihuahuan Scorpion (Diplocentrus whitei) is one of the three Diplocentrus species found in Texas.
It’s named for the Chihuahuan Desert, its main stomping ground.
Diplocentrus whitei stands out with a few key features:
- Color: Usually reddish-brown to dark brown
- Size: Medium, about 2-3 inches long
- Pincers: Thick, heavy claws
- Tail: Shorter than most scorpions
They’re partial to rocky places with lots of nooks and crannies—under rocks, tucked beneath logs, or in little burrows scattered around western Texas, especially near Presidio.
Unlike the striped bark scorpion, you’re less likely to find a Chihuahuan scorpion inside your house.
Still, if you’re out hiking or camping in their territory, it’s smart to stay alert.
The venom from D. whitei isn’t much to worry about for humans.
If you’re stung, expect pain like a bee sting and maybe some swelling, but it rarely calls for a doctor.
They’re sometimes mistaken for other Diplocentrus species since they look pretty similar.
Experts usually need to check some finer details to tell them apart.
Chihuahuan scorpions hunt at night, going after insects, spiders, and sometimes even other scorpions—Centruroides gracilis, for example, if they cross paths.
5. Lesser Stripetail Scorpion
The Lesser Stripetail Scorpion (Centruroides hentzi) is one of the Centruroides species found across Texas and much of the southeastern United States.
It’s a common but often overlooked member of Texas’s scorpion community.
Centruroides hentzi has some distinctive traits that set it apart:
- Color: Pale yellow to cream, sometimes with faint darker stripes
- Size: Small and slender, typically 1-2 inches long
- Pincers: Narrow, delicate claws compared to other scorpions
- Tail: Relatively thin with a curved stinger
They love wooded areas with plenty of hiding spots—under loose bark, fallen logs, leaf litter, or rock crevices.
You’ll find them throughout East Texas forests and into the Hill Country, basically anywhere there’s decent tree cover.
Unlike their desert cousins, Lesser Stripetails are more likely to turn up around homes, especially if you’ve got woodpiles or natural debris nearby.
They’re not as bold as striped bark scorpions about wandering indoors, but it happens.
The venom from C. hentzi is pretty mild for humans. A sting feels like a bee sting with some localized pain and maybe minor swelling, but rarely needs medical attention.
They’re easily confused with young striped bark scorpions, though the stripetail’s more delicate build and woodland preference help distinguish them.
Lesser Stripetails hunt nocturnally, targeting small insects, spiders, and other tiny arthropods that share their forest floor habitat.
