Deby Cassill in 2009 broke with tradition and calls certain periods of rest in ants sleep.. Working with fire ants, she videotaped ants in an artificial nest. She created an artificial colony with three queens, 30 workers and 30 larvae. Checking the posture and position of the antennae, she concluded that queens sleep 90 times per day for 6 minutes per nap, whereas workers dosed 250 times per day for roughly one minute at a time.
It depends on what you're doing. Usually you get between 6 and 7.5 hours. I remember one time, however, that we did not get any sleep at all. It was at Ft. Dix.
