Pheidole is a genus of ants that belongs to the ant subfamily Myrmicinae. In biology, a genus (plural genera) is a grouping in the classification of living organisms having one or more related and morphologically similar species. ...

The genus Pheidole is a widespread and ecologically dominant genus containing as many as a thousand species (Wilson 2003). Most species of Pheidole are tri-morphic, which means that a given colony contains three kinds of ants: (1) the queen(s), (2) the "minor workers," and (3) the "major" workers, or "soldiers," which generally have enormous heads and mandibles in comparison to their usually fairly modest body size. These distinctive major workers have earned the genus Pheidole the nickname of "Big headed ants." It is important to note that the majors of a Pheidole colony, while they may look fierce, are often quite shy and are often the first to flee on any hint of danger. In most cases, the major workers are utilized within the nest to break up large food items, or outside to carry large items.
Pheidole is the second largest genus of ants in the world with 898 species and subspecies with an additional 3 species known from fossil records. They are found world wide. About 53 species and subspecies are known from Australia and these can be found throughout the continent in all habitats (see map).
Pheidole is most similar to Aphaenogaster and Pheidologeton. They can be separated from Aphaenogaster by the 3 segmented (Fig.
While Pheidole workers are well known for harvesting seeds, they are also general predators and will take a wide range of food items, such as this terrestrial amphipod (photo by Steve Shattuck).
