• Veromessor pergandei

  black harvester ant, desert harvester ant

  Veromessor pergandei is a desert seed-harvester ant native to the southwestern United States and Baja California, Mexico. The species exhibits geographic variation in colony founding behavior: single queens (haplometrosis) in wetter western regions versus cooperative founding by multiple unrelated queens (pleometrosis) in drier eastern areas. Mature colonies contain over 35,000 workers and construct conspicuous nest disks with vegetation-cleared centers and fertile rims. The species plays significant ecological roles as a seed disperser, soil engineer, and prey species.
