One June 13, 2017, I caught a queen at a light at night that I eventually identified as Tetramorium bicarinatum. This is an invasive species of Tetramorium that has been successful across the world and is present in Southern United States. The queens are semi-claustral and colonies are polygynous. I have also heard they are capable of very fast growth and can get reproductive alates at only a few hundred workers -- and then breed in the nest, creating more queens.
After catching the first queen, I caught 3 more over the next few weeks. I put all four queens together. In a few days, they laid eggs. One queen died of natural causes after a few days.
I noticed that they kept laying eggs and then eating them. I was feeding them very often so I had no idea why they were doing this. I decided to split them up to see if they would do better by themselves, but I ended up keeping 2 together and leaving one queen single.
Now, I am making this journal on the single queen because she is starting to do very well now after laying her own eggs by herself.
(All four queens together with a few eggs, June)
These queens are each 4.5mm in length.

Today she laid several eggs and her largest larva will pupate any day now. The largest larva is more than half the queen's size. I have not even seen Tetramorium bicarinatum workers/colonies in my area so I am excited for this queen to get a colony. It was definitely surprising when I caught them.
