How to sex scorpions

[Young_Gun]

Males have larger pectines which have more 'teeth' and provide a more comblike appearance than females.

To sex your scorpion with the minimum amount of stress gently coax it into a cricket tub/takeaway container etc and then you can easily see the pectines (which are underneath the scorpion just before the last set of legs) and this also helps when taking pictures for definite ID.

this is definately the way to do this. A lot of people i know look at the pedipalps, looking at the granulations and the curviness of the inner surface. However this does not work for most species.

in some species, if i'm not wrong, the pectines are not different enough to tell apart, if at all.
if people could post their data about individual species like this, it'd be great!
i have a number of unsexed individuals of the following spp, and i'm unsure how to sex, whether by pectine or other method.

Opistophthalmus wahlbergi
Caraboctonus keyserlingi
Bothriurus keyserlingi
Bothriurus coriaceus
Iomachus politus
Hadrugenes paucidens (i think. sold as troglodytes, but not convinced)
Vaejovis spinigerus

one of the problems is being unable to compare to sexed individuals, so pics would help thanks!

I'm a rat snake/tarantula person and i'm seriously thinking of getting Emperor Scorpion/s.

The items i have at the moment is substrates of either Cocofibre/Vermiculite/Forest bed and heatmat 6x11.

Which is the best option as i have been told virmiculite or forest bed type.

The setup i'm getting is as below.

Viv 48x31x18cm
Thermometer
Hygrometer is there anything i have forgotten beside what i have already and hide/water bowl.

Shop where i get my snake/tarantula food from can get me less-tail whip can i use the same type of setup for a emperor.

As said in previous message above posted.

That was very interesting, I always wondered what sex my scorpion was, and now with your ingenuous method i now know its a male. Thanks.

Are there any more ways of sexing scorpions? I've been told something about the part just above the pectines. Something about it being split or one piece. Not quite sure.

Incidently, this is also similar to how you sex whip scorpions (uropygids).

What age can Emps be sexed from?

2 of my little ones are dancing with the side of their house next to each other atm so i am getting a good look at their bellies and there appears to be a noticable size difference in their pectines.

Is it likely they are male and female or do size differences in youngsters pectines not really matter? (they are about 3" atm).

They can be reliably sexed from around L3.
