The Geonosian hive was the elementary organizational structure of the Geonosians, a semi-insectoid species from the planet of Geonosis. Each hive was divided into three castes: the queen, the aristocrats, and the worker drones. In the event that the queen died, the hive was abandoned. Known Geonosian hives included Gehenbar, Golbah, and Stalgasin.
