Where Do Flies Go to Sleep?
WouterIf you’ve ever wondered where flies sleep, you’re not alone. Most insects sleep on surfaces and don’t build nests or live in colonies. Instead, they seek out a place that’s safe and comfortable to rest before sunset. The most common spot for flies to sleep is the underside of a leaf or twig. Alternatively, they can also take refuge under a rock. Just make sure that the surface isn’t too cold, too hot, or too damp. Otherwise, flies run the risk of getting eaten by hungry birds or frogs.
Flies have very similar sleep habits to humans. Scientists think that sleep has a function in helping us survive. However, scientists haven’t been able to determine why humans sleep more at night and others don’t. It’s not completely clear how a fly can function without sleep. Thankfully, some scientists believe that sleep is an evolutionary necessity that helps the brain recover and regain energy.
Flies go through two phases of sleep: a light sleep and a deep sleep. The light sleep is shorter than the deep sleep and helps the insects stay alert in case they encounter a predator. During the winter months, flies may not sleep as much and instead flit about in the dark in order to survive. A lack of sleep can have some serious consequences for the insects, as their brain activity is reduced and their memory can suffer.
When flies sleep, they usually choose a location that’s away from predators. Their bodies do not need to be warm, so they may choose a place under a window or under a tree. They can also sleep on floors or walls.
