Giant Vinegaroon

Dear phionex207,
Though this Giant Vinegaroon is an Arachnid  that is distantly related to venomous creatures like spiders and scorpions, the Vinegaroon does not pose a threat to humans as it has no venom.  It is capable of releasing a mild acetic acid that smells like vinegar, hence the common name.  The Giant Vinegaroon is a Tailless Whipscorpion that is also sometimes called a Grampus.

I took a photograph in southern Arizona a few years ago of a scorpion with babies on its back. Can you identify the species from this shot? Thanks.

Arizona Bark Scorpion with Brood

Dear Glenn,
In our opinion, this is an Arizona Bark Scorpion,
Centruroides sculpturatus.  According to BugGuide, “‘sculpturatus’ describes the sculptured appearance of the tergites (dorsal plates)” and that is a distinguishing feature, however, in your photograph, the tergites are hidden by the substantial brood of young.

Giant Vinegaroon

Hi Jennifer,
This harmless Whipscorpion is sometimes called a Giant Vinegaroon because it can spray a mild acetic acid that smells like vinegar.  Unlike Scorpions, Whipscorpions do not have venom.

Hi Bugman,
These guys were found in Peru (Manu National Park), unsure if they are the same species. I have no knowledge at all on these

Tailless Whipscorpion

Hi Sebastian,
We do not possess the necessary scientific credentials to determine if the two Tailless Whipscorpions you photographed in Peru are the same species, and we also question whether an expert would be able to make that classification based on photographs.  We would guess that they are most likely the same species since we doubt there is much species diversity among Whipscorpions found in the same location.

Tailless Whipscorpion

Hi Alexia,
Even though it is related to venomous Arachnids like spiders and scorpions, the Tailless Whipscorpion does not have venom, so it is harmless.  They are shy nocturnal predators that will feed on Cockroaches and spiders and other creatures you might not want in the home.  Though Tailless Whipscorpions are frightening in their appearance, we hope you will learn to tolerate them should you ever encounter another.

Bark Scorpion after bug bombing

Drugged Bark Scorpions?
Location: Arizona
August 19, 2011 2:54 pm
We had our house bug-bombed for crickets about a month ago. Since then we’ve had 2 bark scorpions turn up that aren’t dead but don’t act like normal scorpions. I found one on the floor and another one a few weeks later on my stove as I was going to wipe up after a meal. In both cases the scorpion lay limp and looking dead until touched. When I clamped them with the tongs they put up a good fight, stinging and all. But neither tried to run or even moved at all when there was motion near them. The guy on the stove had been under a paper towel and when it was lifted he didn’t even run.
It’s my understanding that bug poison doesn’t kill scorpions but it seems like it’s doing something to them. Or am I wrong? I’ve only seen one other bark scorpion before and it ran all over the place when it was outed. I thought they were all like that. What’s your take?

Bark Scorpion

Hi Cyn,
We are sorry, but we really don’t know much about the content of the poisons used in bug bombs, nor their effect on Scorpions.  A month seems like quite some time to pass between the bug bombing and the effects on this Bark Scorpion.
