Flies sleep in short periods during the night in various places such as on ceilings and floors. Studies have shown that like humans, flies have sleep and rest patterns.
Flies do not sleep as deeply as humans do and they sleep for much shorter periods of time. Further studies into the sleep cycles of flies are difficult. When studying human sleep patterns, scientists have tools to measure the brain's activity. This type of study is nearly impossible with flies, which leaves many questions unanswered. The study into whether flies or other insects sleep helps researchers learn more about human and animal sleep patterns.
