Deftly Climbing over the large rocks that make up its rugged habitat, this Pogonomyrmex anzensis worker searches for seeds and other plant material. [scroll down for additional notes/references]
At this location (Ocotillo Wells V.R.A.), we saw a few foraging workers with tiny unidentified seeds, and other plant parts. At the Pegleg location (see images in this gallery) we saw many workers retrieving the fallen seeds of brittlebush (Encelia farinosa). Like most other members the genus Pogonomyrmex, P.anzensis most likely supplements its intake of plant material by occasionally scavenging dead insects, or other arthropods. We did not observe any scavenging activity, however, at either of the locations we visited in April 2011.
