Do and Where Flies Sleep? Effect of Sleep on Development

Studies have revealed that sleep can help the flies to adapt to continuously changing situations. It is believed that flies often slip more when they cannot take flight. Therefore, they start sleeping more than usual to let their physiology adapt to new challenges.

Sleep and Development

A recent study by researchers from Washington University has revealed that when flies cannot respond to a changing environment and fail to take flights they start sleeping more. Later, sleep acts as a revolutionary tool to help them adapt to changing factors.

It is believed that sleep is involved in developing creativity and awareness in living organisms. It also helps the living organisms to overcome anxiety.  Similarly, this applies to flies which help them to respond to challenging factors in a better way.

Moreover, the sleeping pattern is actually similar to humans, because, like human babies, flies also need more sleep during the young stage compared to an adult fly.


To study the relationship between challenging factors and the effect of sleep on flies, Shaw, a staff scientist, has removed their ability to fly and has analyzed their response to word its surroundings.

His studies have revealed that baby flies must have to expand their wings after emerging from the pupal, if they fail to do that, they will become permanently flightless. They performed a dissimilar experiment on older flies by removing their wings which resulted in the loss of liabilities and an expanded sleeping pattern than usual.

Researchers say that while analyzing the neurons they have observed that the neurons involved in the development of wings are also linked with the sleeping behavior of flies. Therefore, we can say that any deformity or injury in wings can directly affect the sleeping behavior of flies.

The wing expanding behavior of young flies significantly indicates that the young brain needs more sleep for proper development so that after learning flying, they can easily fly in the world.

Moreover, this sleeping behavior is similar to other living organisms because the variation in sleeping time has some need less time to you take a healthy sleep and some needs more.


Where Do Flies Sleep?

Another most curious question is where do flies sleep? Researchers say that flies are just like humans as they spend plenty of daytime wandering around. Just before the sunset, they start coming back to safe places to rest and take a healthy nap.

Some of their most favorite places to rest are areas underside of leaves, branches, rocks, or within the tall grass. They prefer to take shelter in places that can protect them from environmental factors like rain and wind.

Moreover, flies sleep by hanging with twigs and branches because they cannot sleep safely on the ground. As, on the land, they can get eaten by carnivorous animals.

Flies open sleep during the daytime specifically to be safe from the afternoon heat. During the daytime, they mainly sleep under the tree shades because they cannot resist overheat which can cause them to thirst to death.

However, because of their party nature, they keep wandering at night in search of a perfect dinner just like other nocturnal insects e.g., moths, mosquitoes. Just like other animals, flies also follow a fine-tuned biological clock which helps them to respond to natural conditions and daily routines.

These biological clocks help them to take a beautiful sleep and adapt to challenging conditions. Moreover, to initiate better sleep flies and other animals also contain different proteins which trigger the sleeping behavior according to their environment adaptability.

Like in nocturnal animals these sleeping proteins work in a reversed cycle as they sleep during the daytime and wander around at night.

Interesting Facts About Fly’s Sleep

  • Flowers usually follow a night sleeping behavior; however, they open take short naps in the afternoon to overcome natural conditions.
  • Drugs can affect the sleeping pattern of lies just like they do in humans.
  • Splice cannot resist hot climates therefore this and their majority of the time while sleeping under shady places.
  • If flies cannot complete their sleeping period at night, they will expand their sleeping time to the next day.
  • Improper sleep can also affect their memory.
  • Baby flies need more sleep time to properly develop their brain.
