A fly, like any other flying insect, causes irritation in humans. She buzzes, constantly striving to sit on her face or other part of her body. And with the advent of autumn, it’s completely impudent and begins to look for an overnight stay in a warm apartment. An insect can be a carrier of infections. The question arises: why does a fly rub its paws, if not to disinfect its limbs? What is the point of her movements then?
Why do flies rub their paws?
At the time of embarrassment or expectation of a pleasant event, a person often rubs his palms against each other. Everyone understands such a gesture and no one is interested in deciphering it. But why rub the paws of a fly? Really conceived or rejoice in a successful deal? In fact, in this way they clean the dirt from their limbs and do this not for hygienic reasons.
Why don't the flies fall from the mirror?
Microscopic suction cups are located on the legs, allowing these flying insects to move on a smooth surface. Everyone saw them crawling through windows and mirrors. During the movement of the flies, dust particles are collected on the bristles with which their legs are covered. These small hairs secrete a sticky fluid that is similar in composition to fat, resulting in dirt sticking to them, and the insect loses its ability to move vertically.
What happens if you degrease the paws of a fly?
If the fly loses fat from the bristles, it will not be able to crawl even along horizontal smooth surfaces. Her legs will slide and move in different directions. This is why flies rub their paws. Without the ability to walk vertically, an insect puts its life in mortal danger. Any flying predator will not fail to take advantage of its helplessness and eat it without hesitation. Despite the fact that it can be difficult for a person to catch this harmful insect with his hands, flies do not have a quick reaction. In the fall, they become less mobile, and even wings cannot always save them from certain death.
