Scorpions and UV

Unread post by ScorpionKing » Tue Jun 24, 2008 7:46 pm

Hi Folks
it's been known for many years that scorpions flouresce under UV light (small, directable beam, low power consumption, waterproof, lion proof). Wavelengths of around 395nm are best for scorpions and it's handy to note that UV LED torches are most suitable. Although scorpions show up under UV light, elephants, barbedwire fences and warthog burrows do not. Makes looking for scorpion in big 5 reserve very interesting. Another thing you need to be aware of is that UV light at this wavelength is not good for you eyes (never look directly into the beam). We wear amber safety glasses for prolonged periods of use.

Anyone interested in joining a spider or scorpion related activity (lecture, night walk, weekend away, ID course) should check out the events section of my site. Many of these activities are hosted by wildlife organisations and reserves. Please support them.

Kind regards

Have no clue about the different types of scorpions but I try to stay away from all of them anyway :wink:

This were one of our X-mas visitors one year - he looks like a mean one but he is rather harmless.

I've heard that you can judge how venomous a scorpions' sting will be b the size of their pinchers - the bigger the pincher the smaller the sting!

There is a document on my website which shows very clearly how to tell a highly venomous scorpions from a weakly venomous scorpion. In short, scorpions with thin tails and large pincers (ie Cheloctonus sp.) are less venomous than scorpions with large tails and small pincers (ie Parabuthus sp.)

We have one of the least venomous scorpions in the world. in the Northern parts of the Kruger Park you'll find some of the largest individuals you'll ever find in South Africa. I was recently at Pumashana in Zimbabwe where we found scorpions over 22cm in length. They were so cute!

Scorpion... Your... scorpion (no pun intended) is Cheloctonus jonesii :D

My S.O normally goes out at night hunting for scorpions in the camps at Kruger.
What we have notice is that trees with a smooth bark are scorpion free.
Whereas trees with a rough bark normally are alive with scorpions.
At Satara we found one tree with no less than 17 scorpions in it.

We were fortunate to see a small scorpion sting a brown beetle on a tree. It was with utter amazement that we watched it.
First the little tail came out.
It felts around on the bark and the next moment it stung the beetle and withdrew in to a hole.
The little tail come out again felt around and stung the beetle again and the scorpion withdrew again.
After a while the scorpion came out and pulled the beetle into his nest.
I tried to take photo's but the quality was not good.

Bankies my S.O is also known as the scorpion lady amongst the camp staff.
She normally gather all the children in the camps and show them the scorpion.
Whilst we were in Kruger at Satara after the cricket week-end, a man said to his wife " Kyk die mal vrou met haar liggie" (Look at die mad women with her small light.)
She called him and showed him the scorpion under the UV light.
He jumped back into his tent.
When he came out again, he was wearing shoes with long socks.
Now I wonder who is mad?

Scorpion King can you ID these scorpions for. I have looked around for books on scorpions but could not found any.

This scorpions normal colour is black. This what it looks like under a UV light.

Hi Pieter
your scorpion is a male Parabuthus transvaalicus. He's wandering about in search of females to woo! No Book! There is a really nice book on scorpions called Scorpions of southern Africa, published by Struik and written by some dodgy geezer called Jonathan Leeming.

Kind regards

Hi Jonathan, an honour to meet you - after hubby was stung by a scorpion in KNP and we realized that we had every possible wild life book except a scorpion book, yours was the one we bought the NEXT day.

"In short, scorpions with thin tails and large pincers (ie Cheloctonus sp.) are less venomous than scorpions with large tails and small pincers (ie Parabuthus sp.) "


Strange thing for us was when he was stung, that we looked at this little bugger and could not decide if it had smaller pincers or a smaller tail. They were really the same. But I will never forget the look of it in my life - it was a Hottentotus triliniatus (because of the 3 lines on its back) and according to your book, about the 3rd most venemous in our country?
It was a very interesting although VERY scary and anxious experience...

Hi DuneRichard,

I used to use a UV flashlight with just one UV LED. It worked great for finding scorpions but it didn't give me enough light for photography. I now use an Inova X5 UV flashlight with 5 UV LEDs to find scorpions. I bought this flashlight from a local Dutch supplier which I found through the Internet. If you Google on "flashlight UV" you'll find lots of different flashlights and suppliers.

Hey Karen,

My bet would be the Yellow-legged Burrowing Scorpion, Opistophthalmus glabrifrons, However I might very well be mistaken,
I live 700km away from Centurion, so I don't know the area's scorps very well at all.

Second opinions anyone? :hmz:

Last night at home I had to do a rescue job.
I am not sure if I rescued the dog from the scorpion or the scorpion from the dog.
Which ever way, it was a big scorpion and a bad one.
As far as I have it, it is one of the Thick-Tail species.
What amazed me was the amount of venom that it expressed when I touched it with the braai tongs. :shock:

Scorpoins at night

Unread post by Bundi » Tue Jul 12, 2011 7:31 pm

As a novice, can anybody please tell me which kind of light to buy to enable me to see scorpoins at night?

Also any pointers in this regard would be welcome. I have always wanted to do that, but have no idea.

You need a Ultra Violet light. You find handy little UV torches, so no major layout is needed.

You can order from here: www.scorpions.co.za

A very basic torch is more than adequate.

Hi Imberbe

Thanks! on the subject of Scorpions I have just posted a quick guide to the scorpions of the Central Lowveld which includes the central Kruger. It's free from the download section of my website. The document is about 1.6mb and can be found at :

http://www.scorpions.co.za/index.php?op ... &Itemid=57

Please feel free to distribute the PDF document to whoever would like it. Works well when loaded onto a smartphone. :-)

Kind regards
