Why do mosquitoes like to rub their hands?

Mosquitoes are blood-sucking insects! Blood-sucking mosquitoes are all females. Blood-sucking is to increase nutrition and reproduce. When they are full, they will find a place with water to lay their eggs. Being bitten by mosquitoes is uncomfortable ~! The fly has no nose, but it has another taste organ, and it is not on the head and face, but on the feet. As long as it flies to food, first taste the food with the taste organs on the feet, and then eat it with the mouth. Because flies are greedy and like to fly around, they should taste everything they see. In this way, there will be a lot of food on their feet, which is not conducive to the flight of flies and hinders their taste. So flies rub their feet to get rid of food on them. Because flies have this bad habit, they can be infected with many germs. If flies stand in feces and sewage and fly to food, they will leave germs on the food. In addition, flies have a worse habit, that is, they land on food, not only eat food, but also excrete feces, and put some live bacteria and parasitic eggs in the intestines on food. If people eat such food, it is easy to get sick, affecting their health and even endangering their lives. Is it detailed enough? Hehe ~!
