sciencehabit writes: Ants and bees have reputations as efficient team players. Division of labor is common, with workers specializing in tasks like foraging, building, and brood care. But new research shows that many ants in a colony seem to specialize in doing nothing at all. Lab videos of ants reveal that, out of the “workers,” 71.9% were inactive at least half the time, and 25.1% were never seen working. A small fraction of the ants, just 2.6%, were always active during observation. Previous studies have postulated that inactivity might be temporary, with ants working in shifts dictated by circadian rhythm. But the new results show that the lazy workers stay lazy no matter the time of day.
