What about Geonosian Species

An insectoid species with physiologically distinct subgroups, most Geonosians ar four-limbed bipeds. typically categorised as cruel and barbaric, they possess AN inherent talent for engineering and technical style and a posh set of cultural traditions.

On their homeworld, the Geonosians board hierarchic hive societies weakened into castes. The Geonosian aristocracy has unchallenged management of the employees and therefore the troopers, savagely managing the lesser castes as befits the aristocrats' whims. Rebellion is sort of impossible, given the Geonosian instinct for hive preservation, and advancement within the hive is very difficult--often earned  through ritual battler combat. Rumors of a queen caste arise among outsiders sporadically, however if queens exist, the Geonosians keep them well hidden.

Most Geonosians encountered faraway from their homeworld ar outcasts or human scouts; either means, they're generally chesty and egoistic, with very little regard for the lives of different species.
