The art of war – or wrestling – as a means of sussing out your neighbor

This is from a wondrous article in the NY Times today on ant research (thanks, NN). The mysteries unfold:

Two harvester ants (Pogonomyrmex rugosus) from adjacent nests engaging in ritual warfare, pushing in a display of force but not actually harming each other. It is thought that colonies use these mock battles to gather information about their neighbors. Knowledge about the strength of competing colonies helps ants set territorial borders without loss of life.
