What types of scorpions are found in New Mexico?
All the scorpions living in New Mexico are nocturnal carnivores, so they are most easily seen at night. But did you know that all scorpions glow a bright blueish color under ultraviolet light?
So many times, people take blacklights to help them find and observe scorpions!
Here are the 9 Types of Scorpions Found in New Mexico:
- As a rule of thumb, scorpions with small claws and a large stinger are dangerously venomous, while those with large claws and a small stinger are less. This ID Guide will help you identify scorpions, but please seek medical attention if you get stung.
- Tiny and normally reddish-brown, but can vary in a color—segmented body shaped like a teardrop.
- Eight small legs. Large pincers that are more than twice as long as the legs.
- No stinger!
- Also known as the False Scorpion.
Have you ever seen something that looked like a scorpion but didn’t have a tail?
If you have, well, consider yourself lucky! This tiny arachnid is called a Pseudoscorpion. They are rarely seen and are considered a FALSE scorpion! The Pseudoscorpion is harmless to humans, but since they are predators, they will help keep your home free of small unwanted creatures.
Despite the name, Pseudoscorpions don’t have a tail with a venom-filled stinger. Instead, these tiny arachnids have venom in their pincers that they use to kill their prey. But you shouldn’t have any fear as they cannot harm a human, so there is no need to be afraid of this 1/8 inch (3 mm) arachnid.
Pseudoscorpions are kind of like spiders too because they can make silk! However, they don’t make webs to catch prey. Instead, they use the silk to create a cocoon to use as shelter from cold weather.

Pseudoscorpions are more common than you think! But since they are so tiny, they are often overlooked and live in homes. In addition, their preferred habitats include moss, leaf litter, and under stones, logs, or bark.
#2. Northern Scorpion
- Paruroctonus boreus
- Tan with dark brown stripes on the back.
- Large round pincers.
This arachnid is the most cold-tolerant scorpion in New Mexico.
You will typically find Northern Scorpions near sandstone cliffs. Look for them in a variety of habitats and elevations.

Like other scorpions in New Mexico, this species feeds on small prey like insects. When they sting, venom is injected, which subdues their prey.
Northern Scorpions are nocturnal and rarely seen during the day. To find them, you need to go looking under rocks in the daytime. But please be careful if you do since they have a venom-packed stinger.
Luckily, the effects of a sting are mild and similar to a hornet. You can expect localized numbness, which lasts up to four hours.

#3. Striped Bark Scorpion
- Centruroides vittatus
- Colors vary from yellowish to light tan in adults; younger individuals are darker in color.
- Both have two broad black bands along the tops of their abdomens.
Striped Bark Scorpions are perfectly camouflaged to protect them from predators and to help them hunt for prey.
This scorpion lives in a wide variety of habitats including the desert, deciduous and coniferous forests, and temperate grasslands. Look for them in crevices under rocks, vegetation, old rural structures like sheds, and even houses during the day.

Many people come into contact with the Striped Bark Scorpion every year. Unfortunately, these encounters often happen when someone is barefoot, which can lead to being stung.
Thankfully, their sting is very rarely deadly. But it does cause a good amount of pain and swelling!
#4. Giant Whip Scorpion
- Mastigoproctus giganteus
- Completely black. Their two front legs are antenna-like.
- Their two large appendages are more like claws instead of pincers.
- A long, thin, whip-like tail that lacks a stinger (hence their name).
- Also known as Giant Vinegaroon and Grampus.
The Giant Whip Scorpion is called a scorpion but is missing the venom-filled stinger that most other scorpions in New Mexico possess. You can find them in thorn scrub, oak, and pine forest habitats.

The Giant Whip Scorpion has poor eyesight and relies on its two antenna-like front legs to feel around and detect vibrations to find its prey. Once a victim is located, they use their claw-like pedipalps to crush them to help them consume it.
This scorpion prefers to hunt for various insects, termites, worms, slugs, cockroaches, and other arachnids. They also have been seen eating tiny frogs and toads.

The Giant Whip Scorpion can spray a powerful acid from their anus, which is located on the tip of their tail. This defense strategy sounds like science fiction, but it’s used commonly when they feel threatened.
Oddly enough, this scorpion is often sold in the exotic animal trade as pets. Good thing they aren’t venomous!
#5. Tailless Whip Scorpion
- Colors vary from the blackish-brown or dark brown.
- Large, wide, and flat body with long skinny legs and pincers.
- The name “amblypygid” means “blunt tail.” It lacks a stinging tail like a typical scorpion.
- Also known as a Whip Spider or Cave Spider.
This creepy crawler looks like a spider and is called a scorpion, but it is neither. This species lacks silk glands to make silk or a tail with a venom-filled stinger. The best part about these arachnids is they aren’t harmful to humans!
Tailless Whip Scorpions are found in arid and tropical environments. Even though they’re not actual scorpions, they act similarly in several ways, which is why they are included on this list.

This arachnid is nocturnal and spends its days hiding under leaf litter or inside caves, waiting for nightfall to hunt and eat its prey. If you expose one by lifting the stone it’s hiding under; it will run sideways, like a crab, to escape and seek shelter elsewhere. They are speedy runners!
It is surprising with eight eyes that the Whip Scorpion would have poor eyesight; it is like nature’s sick joke. But this species does not go hungry, as it uses its first pair of legs as antennas (like whips) to help find prey, such as large insects, frogs, small animals, and spiders.
This species is scary looking but very fascinating, and many people have them as pets. And if this species seems familiar to you, it might be because this arthropod was featured in Harry Potter and the Goblet of Fire.
#6. Lesser Stripetail Scorpion
- Hoffmannius coahuilae
- Smaller-sized scorpions.
- They may be yellow or brown with four dark brown stripes under their tail.
- Pincers are smooth. Male pincers are thicker.
This scorpion lives in various habitats and elevations, from desert to rolling grasslands to rocky slopes in the mountains.

Like other scorpions in New Mexico, look for the Lesser Stripetail Scorpion under rocks or other debris. They are nocturnal and like to burrow and stay hidden during the day.
A sting from the Lesser Stripetail Scorpion causes excruciating pain, which can last for up to 30 minutes. Luckily, you should experience no severe medical side effects.
#7. Arizona Bark Scorpion
- Centruroides Sculptuatuas
- Yellowish tan or brownish with a broad body that tapers down to its distinctive curled thinner tail.
- The abdomen has two stripes.
- Two large pincers.
Arizona Bark Scorpions are commonly found in logs (hence the name), woodpiles, under rocks, and inside houses. They are great climbers and like to hang upside down. These scorpions prefer darker places and may be hiding in your drawers, dark cabinets, tub, barn, attic, or other structures.
This species is the most venomous scorpion in New Mexico.

If you should be stung by the Striped Bark Scorpion, it will feel similar to a bee or wasp sting. However, you won’t experience more than temporary sharp or burning pain for about 30 minutes, and medical care is rarely necessary.
BUT, sometimes the sting can cause an allergic reaction, leading to severe abdominal pain, cramping, nausea, seizures, shortness of breath, or difficulty breathing. If you experience these symptoms, then seek medical attention right away!
#8. Giant Hairy Desert Scorpion
- Hadrurus arizonensis
- Large and hairy. Yellow with a dark back and pale yellow between the eyes.
- Crab-like claws and a long bristly stinger-tipped tail.

You will find these nocturnal scorpions in rocky deserts and arid foothills in New Mexico.
These scorpions like to burrow and search for moisture. They spend their days under boards, rocks, and other debris on the ground and sometimes in a deep burrow.
The Arizona Desert Hairy Scorpion is venomous, but it only causes local pain, similar to a honey bee sting. However, you could be allergic to the venom, and that could be fatal. Symptoms include difficultly breathing, excessive swelling, and prolonged pain.
This scorpion is unique because of its very different mating dance called the promenade a deux. First, the male finds a mate, and they grasp each other with their claws and pull back and forth. Once that is done, the male deposits a sperm packet on the ground, then the female picks it up with her reproductive organs.
Young scorpions are born alive and crawl onto their mother’s back and stay there for about two weeks.
#9. Stripe-tailed Scorpion
- Paravaejovis spinigerus
- Yellowish-tan with brownish-tan stripes on the back of its tail along the ridges.
- The tail is thicker than its hand, but both are slender and have brown markings.
- Also known as Devil Scorpion.
This scorpion is commonly found under rocks or other debris in various habitats, from desert floors to rocky hillsides. However, this scorpion tends to look for the most humid areas it can find.
