Miscellaneous Updates

I figure it's about time for a few random updates since I haven't posted in nearly a month, so here they are.

------

I've been trying to downsize my collection a bit, mainly so I could focus on keeping communal species -- I'd rather have a large pile of deli cups if I know that the inhabitants can eventually be housed together. My current collection (scorpions only) has been reduced to:

0.1.0 Centruroides hentzi
0.0.1 Centruroides margaritatus
0.1.0 Centruroides vittatus
0.0.2 Hadogenes paucidens
0.1.0 Hadrurus arizonensis
0.1.8 Heterometrus longimanus
0.0.5 Hottentotta judaicus
0.0.4 Pandinus imperator
0.5.0 Tityus stigmurus
1.4.12 Uroctonus mordax
0.0.1 Vaejovis spinigerus

The only species on that list that aren't communal are the H. paucidens, V. spinigerus, and H. arizonensis. I plan on passing those onto other hobbyists soon. The C. hentzi is an adult female that I've had for over a year so I'm not thinking of breeding her again -- I may just keep her til she expires rather than giving her to someone without knowing her age. The C. margaritatus I've decided to keep until adulthood in the hopes of finding a mate (this is the bicolor morph which is very pretty, and I would love to have a community of them).

Last week I was stopping by the lab I used to work in, and as luck would have it, the woman who spotted the U. mordax that birthed this summer found another one! On the floor of a classroom she was in, no less.

I have no idea how, but a third-instar U. mordax somehow made its way into one of the buildings at OSU. The habitat for this species has to be at least ten miles away. I asked an entomologist in the building if he knew anything about it, and the closest answer he could think of was an escapee from a soil litter sample somewhere in the building.

It sure worked out well for me, though!

------

The same day as the arrival of the renegade U. mordax, I got a package from a friend of mine in Texas -- five third-instar Tityus stigmurus. This is a beautiful orange and black species native to Brazil that happens to be parthenogenic (for those of you who don't know, that means it's capable of reproducing asexually; a mature female will simply give birth to little clones of herself). Hopefully this will be the easiest community I've ever attempted.

------

Last night I was checking on my second instar U. mordax and noticed one in kind of a funny pose. My thought, since it wasn't moving but clearly wasn't in the "dead" pose, was that it was preparing to molt. Later that night a friend of mine to whom I gave one of the other 2I said hers was molting -- after double-checking on mine, I saw the same thing!

None of my other nine from this brood have molted yet, so hopefully they will soon. Some look like they're still to skinny (I hope they begin to feed more). Oh, and I found out another one of the five that I gave away died.

------

A couple weekends ago I was checking on my U. mordax community and lifted a rock where there had previously been one adult and one subadult female -- now, there was one adult female and half of one subadult female.

I took the larger female out in case she may have been gravid (gravid females are known to be less communal across a lot of species). It was dissapointing to see my collection shrink, but as the saying goes, "all scorpions are communal until they aren't."

I thought it may have been due to the size discrepancy, but within a few days my male and the other subadult female had occupied the same hide under the rock. Also, I saw one in the corner when I went to mist, and discovered it was sitting on top of a tankmate. Perhaps I just had a grouchy female.

------

The same female mentioned in the above minipost was taken on a community outreach and gave me my first sting experience with this species. I was a little disappointed at how weak it was -- it barely went beyond "dry sting" status, and that's only because I felt a little tingling after the fact.

If you're wondering, I was attempting to scootch the female off of my hand and onto a student's at the outreach, and she flicked her tail back at me. I felt her stinger connect (like brushing your finger against a pin) but felt no pain -- just a slight tingling a minute later. I figure it was somethign akin to a scorpion "warning shot." I used it as a chance to explain to the students how harmless this species was even if it does decide to sting.

------

And finally, a non-scorpion post.

A friend of mine from Georgia was able to pick up a few brown widows the last time she visited home and told me she had a male if I was interested. I initially had two males; one got eaten by a female and one was more or less a runt that just died.

I picked up a male and female from my friend (they were cohabiting, so I figured that was a good sign) on Thursday night last week (I write this on Tuesday morning). Friday night I introduced him to my only female. There was much web-dancing and moving about the tank, as well as some movement by the female, but I eventually grew bored and left them alone. I returned later and saw the male in position, and could clearly see the reproductive structure unwound from his pedipalp and in the female's ventral opening (forgive my lack of knowledge with spider anatomy).

Shortly after I arrived they separated and the male backed off from the female -- I assumed I disturbed them and he would now be eaten. However, when I checked back in 12 hours, they were mating again! As of last night they were still successfully cohabiting.

I figure I can leave the male in there, as he's been with all the females in my posession and has no further use for me. If he gets eaten, that's too bad; if he stays alive, that's an good example countering the "widow" status of his partner (though she did eat the first male I offered her).

Hopefully soon I'll be able to post pictures of the new T. stigmurus as well as the freshly-molted U. mordax.
