The habits of ants
a) And it is a lesson to us, that no one has ever yet seen a quarrel between any two ants belonging to the same community.
c) The communities of ants are sometimes very large, numbering even up to 500,000 individuals.
d) On the other hand, it must be admitted that 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.
e) It is evident, therefore, that the ants of each community all recognize one another, which is very remarkable.
b) I have over and over again introduced ants from one of my nests into another nest of the same species; and they were invariably attacked, seized by a leg or an antenna, and dragged out.
