I found a bunch of these Crematogaster queens while running a black light just after dark on July 26th 2014, in Pinyon Pines, California. These queens were fairly large Crematogaster queens, at around 11 mm. Some of them tore their wings off by the next day, and some left theirs on. The vast majority of these were fertile, and they produced pretty quick.
By now many of them have died, and a few have been given away or sold. I now have three colonies of these left, and two of those aren't doing too bad. I've been keeping them in small test tube-sized foraging containers, and today I just moved the best colony into one of my regular foraging containers. This colony has about 10 workers, and a pile of about 35 larvae.
