[Image 1 of 2] As mentioned earlier, these Pogonomyrmex anzensis
ants did not stand still, or congregate around the nest entrance - making them very difficult 'moving targets' for imaging. Thankfully, a couple of workers paused for a few moments to engage in some self-grooming behavior. The forelegs were drawn along the length of the antennae, and also inserted between the ants' mandibles. Not visible in these images are the tiny pectinate (comb-like) tibial spurs
on the ants' forelegs. These structures, combined with grooves on the legs themselves form the tibio-tarsal antenna cleaners, through which the antennae are drawn.
