Why flies are always frustrating their hands, and why are flies rubbing their hands

I'm too dirty, so I'm rubbing my hands, hehe!!

Fly hand rubbing is a physiological phenomenon of flies and a way for flies to clean themselves. Flies move everywhere and do not remove the dirty substances on their bodies, which will increase the weight of flies and affect their flight. Flies rub their hands together to clean themselves and maintain their sense of flight, crawling, and taste.

When flies land on a smooth surface such as glass, the hairy tips on their feet secrete an adhesive fluid that helps them stand firmly.

These liquids can also get on other things, causing flies to be unstable when they land and affect take-off, so flies rub their hands.

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".

Fly hand rubbing is to keep hands and feet clean and spread commensal bacteria, which can reduce weight and facilitate flight. In addition, flies have taste receptors on their hands, and they need to keep their sense of taste sensitive by constantly rubbing their hands.

If you look closely, you will see that the flies will keep rubbing their hands once they stop, so why do flies always rub their hands?

1. Keep your hands and feet clean: 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, so why do flies always keep rubbing their hands and feet. 2. Maintain a sensitive sense of taste

Flies have taste receptors on their feet, which means that we humans need to put food in our mouths to taste it, but flies can taste it by dipping it on their feet. So when the flies stop, they will constantly dip around with their feet, taste the taste, and rub it again, the purpose is to clean the taste receptors, remove the old taste, and then dip it again, and then taste the new taste. It's no wonder that the fly we see always walks around and rubs its feet as it stops, and we don't expect it to be savoring it everywhere.

3. Spread symbiotic bacteria: whenever flies fly over the dirt, they will land on it, crawl around on it, rub it around with their feet, and stick the bacteria on it to their feet, when the fly completes this task, it will take off again, and then fall on the human food, start to rub the feet, rub the bacteria on the feet, the bacteria will fall on the food, the transmission process of the bacteria will be completed, when the people eat these foods, the bacteria will enter the human body, and parasitize in the human body, It has a symbiotic relationship with bacteria.

4. For the sake of face: Studies have shown that when there are many flies present, flies rub their hands more frequently, that is, flies are more willing to clean themselves when there are other flies present. It sounds a bit like us, we always clean ourselves up when we go out, so the flies probably want to let other flies see the good side of themselves.

Scientists have found that female flies have more cleaning behaviors than male flies, and the motivation for this may be to attract the opposite sex.

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???

Fly hand rubbing is a physiological phenomenon that exists in the fly itself, and it is a way for flies to clean themselves, "hand rubbing" is to remove the dirt on each "hand" and maintain its agility to fly, crawl and taste. Flies move everywhere and have a lot of dirty substances on their bodies, and if these substances are not removed, they will increase the weight of the flies and affect their flight. <

Flies move everywhere and have a lot of dirty substances on their bodies, and if these substances are not removed, they will increase the weight of the flies and affect their flight. The suction cups on its hands and feet are attached to the surface of objects when it lands, and it is not easy to walk when it stops.

When flies land on some smooth surfaces, such as a piece of glass, the hairy tips on the feet will secrete an adhesive liquid that can help the fly stand firm on these smooth surfaces, but these liquids will also get on things, so that the fly will not be able to stand on its feet when landing, and it will also be difficult to take off. So to keep it clean, the flies rub their hands back and forth.
