Arizona Bark Scorpion – Centruroides sculpturatus


Known as one of the most dangerous Scorpions in the world, the Arizona Bark Scorpion is one that people are very worried about coming into contact with. They are believed to have venom that is comparable to deadly snakes. They are very hard to kill too given the fact that they have been found around Ground Zero with no adverse effects.


The Arizona Bark Scorpion can range in size from 2 to 3 inches. It really depends on where they are located. They are a very light color so that they blend in well to the various desert elements. They have a very long tail and limbs. Like all Scorpions they have an exoskeleton that they will shed several times called molting.


As you may have been able to figure out from the name, the Sonoran desert is the prime location for this species of Scorpion. It is found all over the Southwest United States and northern Mexico. They tend to stick to the desert regions. They have a very toxic type of venom. They tend to live in the hot sand but will stick to the shade during the day. That is because the bright sunlight is something they are very sensitive to.


One of the most unusual behaviors of this Scorpion is that they will live in large packs. Almost all other species have been known to live a solitary lifestyle with the exception of mating and of carrying for their young.

They have been used in lab experiments to be frozen for weeks. When they are thawed out they move around and go about normal behavior as if nothing occurred. These are very aggressive Scorpions and it is best to avoid being around them when possible. However, they are only aggressive when they feel threatened.

Diet /Feeding

They tend to ambush their prey by hiding in a type of burrow they have dug. Then they will come out and sting them from behind. They can also hide behind rocks and just wait for prey to come along.

Their diet consists of roaches, beetles, and crickets. They will eat anything else they can find though as they are very opportunistic. The venom that they inject into the prey is very powerful. It doesn’t take long for them to liquefy and then the Scorpion can drink it.


This particular Scorpion will be mature for mating around 1 year of age. This is much younger than most other species with the average age being 5 years. The males have to entertain the females and dance with them in order to have a chance of her agreeing to the mating process.

The average size of a liter is from 25 to 35 of them. They will climb onto her back after being born so that they are safe. She will carry them around for the first couple weeks of life until they go through the first molt. The average lifespan is 6 years.

Venomous Bite /Danger to Humans

There is definitely going to be pain should someone get stung by the Arizona Bark Scorpion. Many people report feeling some form of “electrical current” after intoxication with venom.

The elderly and the young are the most at risk. In North America this is the most dangerous of all Scorpions in terms of the venom. Some of the common symptoms include swelling of the area, frothing of the mouth, and trouble breathing.
