Types of Scorpions that live in Wyoming

 

All the scorpions living in Wyoming 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 out in the desert to help them find and observe scorpions!

Here are the 2 Types of Scorpions Found in Wyoming:

  • 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

Common Wyoming Scorpions

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:

  • Tan with dark brown stripes on the back.
  • Large round pincers.

 

This arachnid is the most cold-tolerant scorpion in Wyoming.

 

You will typically find Northern Scorpions near sandstone cliffs. Look for them in a variety of habitats and elevations.

Like other scorpions in Wyoming, 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.
