I recently acquired 2 small Messor barbarus colonies, each with about 10 workers. I put them into 2 test tubes with water and cotton stoppers for the time being, until I can build a more suitable enclosure.
I went home from college over thanksgiving, and apparently on the car ride, the stoppers somehow worked their way out of the tubes I had them in, and one of the colonies "moved in" with the other one, all the workers/brood and queen are now in the same test tube as the other colony. They don't seem to be fighting at all, and I've been observing them for several hours.
My question is, do I need to separate them again? M. barbarus is monogyn as far as I know, so this seemed strange to me, and I'm afraid the workers may end up killing one of the queens.
Also, I know this species has hibernation requirements, but I've also heard about people not hibernating them with no ill effects. What's the general consensus on this requirement, and what are the specifics (ie temp and humid.) I need to keep them at for hibernation, and for how long?
Thanks for your response.
