Why do flies keep rubbing their hands ? Is it because it s too cold?

If you have ever observed a fly, you will find that when the fly stays in a certain place, it will always make a "hand rubbing" motion, as if it is ready to catch its prey, but nothing happens. Why do flies always rub their "hands"? Is it because it's too cold? <>

People with big brains will think that maybe flies really need to "rub their hands" to keep warm, just like we like to rub our hands when we go out without gloves in winter, is this also the reason why flies rub "hands"? This question is one of the research topics of Professor Hu Lide, and the projects he is working on seem to be boring at first glance, which are difficult for ordinary people to think of, but in fact, it is his various seemingly strange research that makes us discover that there is interesting knowledge everywhere in life.

So why do flies always rub their "hands"? Of course, it's not because it's too cold, they rub their "hands" to clean up! This seems a little unacceptable, flies are in our impression of being very dirty and do not like to be clean, they are still hygienic?

Through research, Professor Hu Lide's team found that the "hand" rubbing behavior of flies is the same as the behavior of humans bathing and cats rubbing "hands", in order to clean up their own hygiene.

Everyone should have observed the behavior of cats rubbing their "hands", and cats who love cleanliness make themselves white and flawless through skillful movements, which is very cute. Flies also have their own set of cleaning actions, and a closer look will show that their "hand" rubbing usually involves rubbing each other with two forefeet, two with the forefoot rubbing the face, two hind feet rubbing against each other, and two hind feet rubbing with their wings. Once these actions are complete, the flies wash themselves thoroughly.

Fly rubbing "hands" is not just for cleanliness, researchers have found that fly rubbing "hands" is also very helpful for the physiological activities of flies. Rubbing their hands allows them to fly better. Because flies often burrow into feces and stinky gutters, after they finish flying, they will stick a lot of filth on their bodies, which will increase weight and hinder flight.

So they have to keep rubbing their hands together to clean themselves up for the next flight activities. <>

Flies rubbing their "hands" can also help them maintain their sense of taste. This sounds a bit outrageous, but what does hand rubbing have to do with taste? In fact, because the taste receptors of flies are distributed on the feet, humans need to put food in their mouths when they taste food, and flies need to "taste" with their feet.

If you look closely, you can see that when the flies stop on the food, their feet get around, which is actually tasting the taste. Sometimes they will rub it first, because there is too much dirt on their feet, which affects their taste of "food". It turns out that there is so much knowledge hidden in the little fly, and interesting knowledge is hidden everywhere in life, but only those who have a heart will find it!

No, there are no flies when the weather is cold, it is not suitable for flies to survive, rubbing hands is because the hands are too dirty, and patting the dirty things on the hands is convenient for eating.

This is definitely not because the weather is too cold, because flies only appear in summer, and there are no flies in winter, so there is no fly rubbing hands because of the weather, this is just a matter of fly habits.

Flies always rub their "hands", not because the weather is too cold, this action of flies is to ensure that the hands of flies are clean, to facilitate them to spread bacteria, and to reduce their own weight, more conducive to flying, and there are receptors on the hands, such an action can also ensure that the sense of taste will not be destroyed, and it will be more sensitive.

The reason why flies rub their hands as soon as they stop:

By observing the living habits of flies, it can be found that flies are animals that like to "rub their hands" very much, and they like to "rub their hands" as soon as they stop. In fact, this is a fly cleaning its own body, although the fly is very dirty, but there is also a need for cleaning.

They fly around the garbage heap every day, and their bodies will inevitably get dirty, which will affect their flight, so the flies need to stop and "rub their hands".

Every time I see flies falling on top of objects, why do I always see them rubbing their hands, is it really because they love to be clean?

Why do flies always rub their hands???

1. Fly hand rubbing is a physiological phenomenon that exists in the fly itself, and it is more common to say that this is a way for flies to clean themselves, and "hand rubbing" is to remove the dirty things on each "hand" and maintain its sensitivity to fly, crawl and taste.

2. Flies move everywhere, there are many dirty substances on the body, if these substances are not removed, it will increase the weight of the fly, affect the flight, after staining something, the suction cups on its hands and feet are adsorbed on the surface of the object when landing, and it is not easy to walk quickly when it stops.

3. When the fly falls on some smooth surfaces, such as a piece of glass, the tip of the fur on the foot will secrete a liquid with a certain adhesion, which can help the fly stand firm on these smooth surfaces, but these liquids will also get on things, so that the fly will stand unstable when landing, and there will be problems with take-off. So to keep it clean, the flies rub their hands back and forth.

Flies are a common insect and sometimes we observe them rubbing their hands when flying or staying. So, why do flies rub their hands?

It is worth mentioning that flies also spit saliva to clean their sensory organs while rubbing their hands. Saliva contains some digestive enzymes and antimicrobial substances that can help flies remove bacteria and other microorganisms from their sensory organs.

Actually, the reason flies rub their hands is to clean up their sensory organs. The sensory organs of flies are distributed in the head, chest, and legs, and these organs help them perceive information such as temperature, humidity, smell, etc. from the outside world. However, since flies often stay in dirty places, some dust and bacteria can be stained on the sensory organs, affecting their ability to perceive.
