I normally keep all my ants in one journal, but I figured these guys are special enough for their own journal.
A couple days ago (the 16th), I bought a colony of Trachymyrmex septentrionalis. They were collected from Sand Ridge State Forest in central Illinois. They're a decent size, with about 290 workers and four queens. Apparently the T. septentrionalis in the Sand Ridge population are polygynous, rather than monogynous/pleometrotic. From what I've seen so far, this seems to be accurate. I can't see any queen favoritism. They seem to be at a size where they would be monogynous one way or another, either via pleometrosis or via "worker queens", so hopefully the polygyny is here to stay.
They are currently housed in a tupperware with a plaster layer and a tubing hole. The outworld is a larger tupperware with a layer of dry sand at the bottom.
They don't have much fungus since they came out of hibernation recently. Over the past couple days they've disassembled the various smaller fungus gardens and integrated them into main ones. As of today there are two main clumps of fungus, and they've taken on a more spherical shape.
They don't appear to be very hungry, probably due to the small size of the fungus. They've been accepting food, but very slowly, only one piece every now and then. So far their reactions to food have been:
- Trifolium repens leaf — Only accepted it once I cut it up for them and after it began to dry out
- Blaptica dubia frass — Accepted. I don't have access caterpillar frass but I figured this was close enough
- Oxalis sp. — Ignored
- Sedum ternatum flower — Ignored
- Rose petals — I am yet to provide them with any rose petals myself, but they do collect the dried up rose petal pieces scattered throughout the outworld.
- They spent a lot of time trying (and not getting very far) to cut up some small dried-up purple berry
