Pogonomyrmex
is an iconic ant of deserts and other arid habitats in North and South America. These conspicuous insects are normally granivorous, playing ecologically important roles as scavengers and seed dispersers. Pogonomyrmex is also known for having a uniquely painful sting.
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.
