Update 17 (17/02/20)
"Wow - another update? This Nare guy's really good about keeping his journal up-to-date unlike someone else whose name starts with the letter 'L' and ends with a '3'"
Yes, it's true - another update, and not even a whole month after the previous one. Where to start...
The Zootermopsis nevadensis are still doing really well. I feel their wood might be running a little bit thin, so I've connected up another test tube for them to forage / move into should they feel the need. The real test here is to see whether or not they like the wood - LC3 said these termites grow very well on a particular wood that I have been unable to identify and obtain, so I'll just hope they do well on some of the brown stuff. I believe it's a rotten softwood of some sort, collected it from a forested area that should be pesticide free - it's soft enough that I can break it apart with my hands. Anyways, here's a pic of their current setup:
Also, that presoldier that I spotted in the previous post has molted into a proper soldier. Here are some pics:
Unfortunately, the colony has plastered the sides of their tube with poop, so it's getting harder and harder to see what they're doing. However, it looks like everything is still going well - always lots of eggs, still all 4 imagoes as far as I can tell, and more and more workers every day. Very exciting stuff.
Now, for the Reticulitermes. Don't remember if I included this in the last post, but unfortunately all of the workers in one of my founding Ret colonies dug out of the cotton and ended up drowning in the water of the moisture chamber. Thankfully, both imagoes were still alive and well, so I stuffed a small test tube with some of the aforementioned rotten softwood and introduced the two. They dug right in and were gone from view within a few hours. A few weeks later, I checked on them, and found that I could see some antennae through a gap in the wood. And then I saw another pair. So I assume the two are still alive and well. I'm unsure as to whether they have any eggs again, but I hope they'll make a full recovery.
With their success in mind, I decided to move the other founding colony into a similar test tube. I gently pulled their current tube apart...
... and placed them all in a new tube.
All of their workers made it over just fine, and when I checked on them today, they were busy burrowing into the wood. I'll provide some pictures when they make more progress in the next update.
Finally, I just wanted to report on some progress that I'd made today. Some of you may remember my Ret tub, just a container full to the brim with wood that had had termites in it upon collection. I'd been neglecting it and putting off sifting through the whole thing to extract termites, and this weekend I finally sat down to work my way through it, only to find that most of the wood was devoid of termites - isopods, springtails, and centipedes (dreadful creatures) sure, but no termites. Except for a single piece:
The container had been full of wood mulch / soil similar to this:
Anyways, upon chipping away at that larger piece of wood, a soldier popped out:
And when I dug deeper, I found some more workers, an angry soldier who was none to pleased to see me, and, this is the best part, some larvae:
This suggests that, somewhere in this piece of wood, there are two or more reproductives, and enough workers to support them. This is practically a first for me, as the only other time I managed to raise a colony splinter to larvae, the colony died out within a matter of weeks. Hopefully the same fate will not befall this colony.
Anyways, I moved them into a new setup to try and maintain humidity. I also offered them a chunk of the rotten softwood just to see if they would bother with it at all. Here's a picture of their setup:
Yes, that's Saran wrap, and that's because these containers unfortunately lack lids. The piece of wood the colony is in is too large for some of my containers, and too small for others, so I decided to just cobble together this setup and forget about things looking nice. I poked some holes in the Saran wrap to facilitate gas exchange. Here's hoping this colony does alright.
Anyways, that's about it for this update. I'll get some pictures of the founding ret colony that I moved into the wood test tube, and I'll be sure to update you all on any other happenings. There might even be some new termites by then...
