Why Does Flying Exist?
WouterIf you’ve ever wondered why flies exist, it’s probably because they’re useful to our world in a variety of ways. For one thing, most species of flies are important for natural decomposition, as they feed on dead animal carcasses and trash. In addition, some species feed on plants, such as dandelion seeds. They’re also an important source of pollination and help clean up dung.
Adult flies usually live for about 15 to 25 days, but some can live up to two months! The right temperature and food will increase the duration of their lifespan. Furthermore, they are likely to live longer at cooler temperatures. They also need food before they can reproduce. Typically, female flies need between two and fifteen minutes to copulate. During this time, female flies need protein. However, manure does not contain enough protein to sustain their life.
While flies lack the mouthparts to chew their food, they can drink it. The digestive juices that flies regurgitate onto solid food break down the food into small pieces and are expelled as fly specks. Likewise, they have sensory receptors on their legs and feet that allow them to taste their meal. This means that when they’re hungry, they’ll walk around looking for their next meal.
Another way to answer the question of why flies exist is to understand how flies came to be in the first place. According to scientists, humans evolved out of Africa. These early people eventually became the first civilizations in the world, and they had cities such as Uruk and Eridu.
