Caption: When an H. saltator colony's queen dies, the female workers engage in ritual fights to establish dominance. Ultimately, a small group of workers establishes dominance and become a cadre of worker queens or "gamergates." The gamergates look like ordinary workers, but undergo extreme internal changes: their brains shrink by 25 percent; their ovaries expand to fill their abdomens; and their life expectancy jumps from about six months to several years or more.
