So, about a month ago I made a Vivarium. I'm not going to go step by step on how I made it, I'll just skip to the important part. I had just finished putting in the soil and was adding the hard objects, rocks, sticks, etc. I had found a pretty interesting small stump looking thing that was just the right size for the center of the Vivarium, little did I know that would be the whole thing that set this Vivarium apart from any other I've made so far.
Fast forward to a couple weeks later. I looked into the Vivarium and noticed a Ponera worker running around, it then went into the small log and I didn't think much about it. A couple days later I check on the Vivarium and I notice the Ponera worker again, I start to realize while I'm sitting there watching it that there is actually two workers running around, then I think I might see a third but I'm not sure. They all lead to the same place, the stump.
Fast forward to yesterday. I looked inside the Vivarium and noticed what I originally figured to be a Ponera worker, then upon closer inspection I realized it was definitely not a Ponera worker the problem was I had no clue what it was, it looked like a mini version of a Myrmica sp. but I figured there was no way a Myrmica Species could get that small. After a bit of researched I ID'd it as Myrmicina americana, a very cute species if I do say so myself.
Fast forward to today. I look inside and spot a Ponera worker (maybe two) a couple Myrmicina workers and even a couple lasius umbratus workers. Everything is pretty easy to find now that I know where it is. But those weren't all I found, to my utter surprise and delight I found a Camponotus Subbarbatus queen just chillin' in a hole in the log, taking a nap.
I'm pretty sure the Camponotus Subbarbatus queen doesn't have workers, because if she did why would she be in such an open place? But who knows. Basically though this really made me realize how much nature could be jam packed in a single, seemingly boring, log. and I mean its like 5 in. by 2 in. I will try to get more pictures but it has been a pain in the butt since the ants are so small and lighting is impossible to get right and there is soooo much foliage, but I'll try anyways. If anything else happens I will also update it on here. Bye!
