Phoenix Mountains Preserves
I made a 3 km loop north of North Mountain through upland Sonoran Desert scrub habitat. My main purpose was to survey for ants which in most every place are very active immediately after rain. Throughout the loop I found only 3 occurrences of Forelius, 2 of Solenopsis and no Myrmecocystus, Novomessor, Veromessor. Finally only one colony of Pogonomyrmex was found near an artificial water impoundment.
