This journal will document the development of my captive Tapinoma sessile colony.
I found a single Tapinoma sessile queen alone beneath a rock on a wooded trail in Loveland, CO on July 13, 2014. The area had a high concentration of Tapinoma sessile colonies - in fact, T. sessile seemed to be the most dominant species by far. The trail was at the edge of a lake and had predominantly sandy/soggy soil. The collected queen laid eggs shortly after settling down in a traditional test tube setup. Now, she has what seem to be three large pre-pupae and a few small larvae. It looks as if the first workers will be larger than I expected, compared to the queen’s tiny body size. I probably won't take any photos until the workers eclose, since I don't want to disrupt the founding process.
I'm interested to see whether this colony will eventually become polygynous, considering that intranidal mating is supposed to be common in T. sessile.
