tetramorium question involving people in Europe

I have never seen a single tetramorium polygene beyond the nematic state. They will group together but, will fight when workers arrive. T. caespitum is not native here and is not believed to even be in the U.S. any more.

The information regarding "Pavement Ants" (T. caespitum) on the USA site, does tend to make me question their source of reference
To say that the species is polygynous in the States, when it is strictly monogynous in Britain and Europe, makes me wonder who has done the study to observe a colony with more than 1 queen?

I too have heard that it is doubtful that this species is still resident in the USA; but I reserve judgment on that score, as I am not a USA member and have never been there sadly. Although I would love to observe ants such as Pogonomyrmex in the wild; and certain areas of the USA have such fascinating species, even though they may be considered as pests by the local inhabitants of the particular County or State.

Interesting. It could be that when populating vast open spaces new colonys "bud" to colonise the area before becoming monogyn again? What do you think?

I don't think they would do that. Maybe next year I will try and see if a multi colony will bud by giving them few home options. I don't think a war like ant will do that though but, rather keep the competition away from them your never let it happen.
