Heute habe ich ein Experiment mit meinen beiden Ectatomma gemmacht. Ich habe beide in ein Reagenzglas gesteckt. Sie vertrugen sich. Als ich das sah schaute ich gleich im Internet und fand auch was zum Thema Polygyner Ectatomma.

Zitat aus dem Internet:

Natural History

Ectatomma ruidum is one of the most common ants in Costa Rica. It occurs in both wet forest and dry forest habitats. Nests are below ground and may reach high densities in open areas (Weber 1946, Lachaud 1990). The nest entrance is an unadorned and inconspicuous hole in the ground, the hole little larger in diameter than a worker. Workers forage on the ground surface and on low vegetation. They are predators, generalized scavengers, and avid collectors of extrafloral nectar. Colonies may be polygynous: Weber observed a colony in Colombia with 13 dealate queens and at least 24 workers. Weber also observed in a lab colony that a worker developed a swollen gaster and began laying eggs after the queen died. It is not clear whether the eggs were viable.
