Harvester ant, is a common name for any of the species or genera of ants that collect seeds. The collected seeds are then stored in the nest in communal chambers called granaries
Ants provide soil aeration through the creation of galleries and chambers, mix deep and upper layers of soil, and incorporate organic refuse into the soil as well as aiding with seed dispersal.
Like all insects, harvester ants have six jointed legs each and hard exoskeletons that protect their bodies. Harvester ants are larger than many ants. Queen harvester ants are at least a half-inch long while workers are about half that size. They range from red to brown and black in colour and many species also have long hairs on the underside of their heads, which is beard-like in appearance.
