[IMAGE 3 of 6] This series of images depicts Pogonomyrmex subdentatus
, and P. californicus
workers fighting. Often, when foraging Pogonomyrmex
workers from different nests (either of the same, or different species) encounter each other, combat ensues. In these images, the larger, lighter colored ant is P. californicus
, and the smaller, darker red ant is P. subdentatus
. Several such fighting pairs were observed on these two days. In all cases, it appeared that both ants were mortally wounded, having antennae, limbs, and often their gasters (hindmost abdominal segment) severed completely. The dead and dying workers remained intertwined. On other occasions, we have observed Pogonomyrmex
sp. workers fight briefly, and then separate unharmed.
