    1) "Do flies sleep? after prodding and tapping fruit flies, measuring their activity with ultrasound and infrared detectors, blasting them with sound waves and monitoring their genes, researchers at the Neurosciences Institute in San Diego have come to a definitive conclusion: the flies actually doze off in slumber patterns that are strikingly similar to those of humans.

    Writing in the current issue of Science, the researchers report that the flies are somnolent mainly at night and active during daylight hours: that elderly (33-day-old) flies sleep less and more erratically than younger ones; that fruit flies deprived of sleep must nap longer to recover; that caffeine keeps them awake, and antihistamines make them that drowsy."

    2) ""Flies do most things that humans do—they eat, they sleep, they fight, they mate, they forage for food," Ganguly-Fitzgerald told LiveScience. Just as is often the case with humans, flies sleep a lot as young ones, sleep little as they get older, and "stay awake more after being fed caffeine and become sleepy in response to anti-histamine compounds," she said."
