The Communities of Ants

I have over and over again introduced ants from one of my nets into another nest of the same species, and they were invariably attacked, seized by a leg or an antenna, and dragged out. | And it is a lesson to us that no one has ever yet seen quarrel between any two ants belonging to the same community. | However, they are in hostility not only with most other insects, including ants of different species, but even with those of the same species if belonging to different communities. | The communities of ants are sometimes. very large, numbering even to 500,000 individuals. | It is evident, therefore, that the ants of each community all recognize one another, which is very remarkable.
