Just wondering if T. immigrans are polygynous as I have a queen already and wondering if I found more since they just flew if I could combine them and make a supercolony.

No they are not. They will start colonies together but once workers arrive they will kill all but one queen

No they aren't. Like Kiedeerk said, and from personal experience, they will stay together until the first workers arrive and then slaughter each other. In really rare cases, however, they will stay together forever.


Currently raising: 

Myrmica rubra (1 queen +  ~5 workers)

Lasius niger (single queen + ~90+ workers)

Lasius neoniger (3 single queen + brood)

Formica spp. (Queen [likely parasitic, needs brood])

Formica pacifica (Queen)

Also keeping a friend's tetramorium immigrans for the foreseeable future. Thanks CoffeBlock!

Yes, like Stubyvast said in really rare cases they could be polygynous, but don't put them together in hopes of that chance occuring. I have done it in the past, and I severly regret killing poor ant queens due to my bad judgment.

if you ever are going to though, I would suggest founding them together, then separating them in too different areas that are connected together. This will lower the chance of the queens fighting amongst eachother, and could possibly act as a polygynous colony.
(js stating what I heard before 😭)

I caught 4 queens I found grouped together under a rock last year. They slowly eliminated one queen at a time until only one remained. This was over the span of about 3 months. For a large portion of that time they had both workers and multiple queens. I haven't tried mixing random queens together, but when I flipped the rock and saw them, they very clearly had chosen to huddle and stay together so I kept them that way to see how it would turn out.
