[IMAGE 1 of 3] While observing Pogonomyrmex anzensis
workers forging, a flash of motion was seen in the tiny crevice under a rock overhang (only about 10 inches from the P. anzensis
nest). A life-and-death struggle was taking place between a P. anzensis
worker and an unidentified spider. The spider was circling the ant at a startlingly rapid pace; attempting to immobilize its struggling prey with silk. In this image, the spider can be glimpsed (though very blurred) in the right foreground. The ant flipped over several times at she attempted to break free. Note the everted (extended) sting
, normally not visible.
