Geonosian

Homeworld: Geonosis
Description: An insectoid species divided into castes, the Geonosians are native to the harsh rocky world of Geonosis. Geonosians construct immense, organic-looking spires within which reside their hive colonies.
There are two main types of Geonosians: the wingless drones that mostly work as laborers, and the winged aristocrat, which includes royal warriors serving as scouts and providing security to the hive. All Geonosians have a hard, chitinous exoskeleton, elongated faces, multi-jointed limbs, and speak in a strange clicking language.
Though labeled "warriors," Geonosians do not have a standing military. They instead use their droid foundries to build armies for corporate interests wealthy enough to afford them -- entities such as the Trade Federation and the Techno Union. Despite relatively simple minds, the Geonosians are adept at mechanical construction, and are contractors to many of the galaxy's biggest manufacturing concerns. They are responsible for the construction of some of the largest feats of engineering ever witnessed.
The hardships of the native environment coupled with rigid structure codified in their caste society has fostered a barbaric side to the Geonosians. Their simple minds view brutal violence as entertainment, and Geonosians congregate in massive execution arenas to watch victims doomed to die by being subjected to savage creatures.
