I just got my less than one year old Teramorium sp. e colony over the 200 worker mark!!! I just did a head count and they have 135+ larvae, 50-60 eggs and 2-3 pupae (most eclosed recently). They are currently living in a Atom C formicarium (which is now fairly dirty and hard to take photos of) and is currently being stored in a wine cooler, where they will remain for the next 4 months. The started as a pleometrophic colony with 12 queens living in a Mini Hearth. Over time (as expected) the number of queens slowly dwindled until two remained. One night while observing them, I watched as one of the queens walked over to the other while she was grooming herself and immediately went for her throat!!! both of the queens curled around one another, trying to sting and bite one another. Eventually however, after 30 seconds of fighting, the aggressor stopped and calmly walked away. Upon leaving her startled victim (who was still in perfect condition), she was immediately engulfed in a ball of workers (which appeared to be watching the fight from a safe distance). I believe these "spectators" were in place to "record" the amount of time the aggressor was able to stand her ground against her rival and perhaps if she can do so for a certain amount of time without getting injured, she will be seen by the workers as the more dominant queen, causing the workers to rush to her aid in dismantling the less dominant / healthy "beta queen". Pheromones may even be used to "tag" the less dominant queen. This might be a completely new, undescribed behavior that takes place in Tetramorium colonies during the selection period. This had happened several times throughout this colonies brief history and I was positive that the dominant queen would leave unscaved, but in the confusion, both were attacked by droves of workers. In order to assure the survival of the dominant queen, I opened the formicarium and removed her / picked the individual workers off of her. during the onslaught, the "beta" queen died from her wounds and was quickly dismantled and fed to the workers. As for the surviving queen, she lost 2 of her legs. I wasn't sure if she would make it, but despite all odds, her colony blossomed forth. I will definitely use pleometrophic founding for this species again (but will remove all but one of the queens once the number reaches approximately 2-4.), which I have seen can work wonders. I am so excited to see what unfolds in 2017!!!!
