Class: Hexapoda (animals with six legs - includes all insects)
If you walk through the meadow area near the intersection of the Bush Mountain and Marcus Trails, you will find a number of large ant mounds (cleared areas exceed 4 feet in diameter). From the description of the nests studied by Moody and Foster (1979) in the same area, this is probably a Maricopa Harvester Ant nest. Some colonies have excavated chambers to a depth of 7 feet or more. For an interesting read check out Stephen Taber's "The World of the Harvester Ant" c 1998.
