What types of scorpions are found in Nevada?

Scorpions species that live in Nevada

All the scorpions living in Nevada 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!

5 Types of Scorpions in Nevada:

  • 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.

#1. Pseudoscorpion

  • Pseudoscorpiones

Nevada Scorpions species

Identifying Characteristics:

  • 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

Identifying Characteristics:

  • Large round pincers.

Like other scorpions in Nevada, 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.

Striped Bark Scorpions are perfectly camouflaged to protect them from predators and to help them hunt for prey.

This species is the most venomous scorpion in Nevada.

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!

You will find these nocturnal scorpions in rocky deserts and arid foothills in Nevada.

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.
