• Formica pergandei

  Pergande's Mound Ant

  Formica pergandei is a slavemaking ant species that constructs stable earthen nest mounds. Colonies exhibit frequent nest relocations, typically occurring mid-raiding season, by invading existing host nests in areas of higher host density. This behavior reduces mean raiding distance and improves raiding success. The species was described by Emery in 1893 and is known from the northeastern United States.
