Gettin a few of these in the mail soon. One adult female and a few slings. What I started thinking about though is that these paricular species adapeted a special "morph". I hope mine is but for those of you that don't know I decided to share a bit of what I know. Tityus stigmurus is non parthogenic scorpion but certain comunities of females have adapted a parthogenic trait. This particular comunity is found in more human populated areas were they species is being killed off. The female/male ratio is 4/1 if I remember correctly. Interesting how humans helped make this particular trait a useful and further "evolve" this species.

yeah, I've got 3 T. serrulatus. there's a publication out about how T. serrulatus is just a morph of T. stigmurus and although all populations in captivity and all populations near a human population density are said to be 100% female and parthenogenetic, there have been populations found where males have existed.

as far as I know, most T. stigmurus in the hobby are also parthenogenetic because it's easier to get a scorp that pops a brood every 4-10mo than it is to track down a male and breed them. needless to say, I'm willing to put my money where my mouth is on this one and say that you're going to be busy with these guys for the next few years.

here's the article from the Journal of Arachnology: http://www.americanarachnology.org/JoA_Congress/JoA_v27_n1/arac_27_01_0154.pdf

That's pretty cool. Interesting that humans would have that effect; I just think it's awesome there's parthenogenetic Very Happy.

(Lame! My Firefox dictionary has parthenogenesis but not parthenogenetic Rolling Eyes)

no prob, I read it over a few times because there's always that debate about T. stigmurus and T. serrulatus being the same scorp

It's case-sensitive . . . "Firefox" is in their dictionary. Rolling Eyes
