Why do flies keep hitting glass?

Flies like to fly to bright places, especially houseflies, often burrow into the room, and after eating and drinking, try to escape from the bright places. Flies tend to see bright glass windows as an escape outlet. However, flies can't see the glass, so they often hit the glass headfirst.

In addition, the eyes of flies are compound eyes, which can see a wide range, but they can't focus well, so they can see things blurry, and the human eye can hit clean glass when they can focus well, not to mention flies that are not focused accurately? Flies fly faster and react quickly, although they are compound eyes, but like human birds, glass is inevitable to hit glass without reflection and reference, and human beings are no exception. The fly sees the window and wants to fly out, but it can't see the clear glass, and it thinks it's empty, so it keeps hitting it.

Flies like to fly to bright places, especially houseflies often burrow into the room, after eating and drinking, trying to escape from the bright places, it often sees the bright glass window as an exit to escape. However, flies can't see the glass, so they often hit the glass headfirst. Not only flies, but also dragonflies and butterflies that were caught in the room.

They bumped into the glass windows, and they must have wondered why they couldn't get out. Flies always like to stay on the lampshade at night because flies like bright lights. We call this property phototaxis.

Many of the insects that sleep during the day and are nocturnal are phototaxis. Such as moths, unicorns, etc. On the contrary, there are phototaxis insects, and there are also negative phototaxis insects that prefer to hide in the dark, and cockroaches belong to this type of insect.

Houseflies have a habit of being active during the day and falling asleep on the ceiling at night. In the first few days after emergence, the adult houseflies form a conditioned reflex after repeated light and darkness many times during the day and night, and after dark, they will naturally fly down to the ceiling of the house to rest.

What kind of defeat is it that flies that fall on the vertical glass surface and not only do not slide down, but can freely crawl on the vertical glass and climb over the rocks?

It turns out that flies have characteristics that are suitable for walking on vertical glass. Each of its six feet has a "claw", and at the base of the claw there is a paw pad plate that is covered by a row of furs. When flies move on the glass plate, the hairy tips of the feet secrete a fluid that has been analyzed to be composed of neutral lipids and has some adhesion.

In addition, the fly's claw pad disc is a bag-like structure with a congested interior and a hollow underneath, acting like a vacuum cup, allowing it to be attached to a smooth surface or hung upside down. No wonder this bad guy wouldn't fall off when he stopped on the top of the glass.

Flies are compound eyes with little visibility! It's not easy to find static transparent glass!

I don't see it, I sometimes bump into the glass.

Flies are compound eyes and cannot see stationary things.

Because the eyes of flies are almost short-sighted.

Just because the glass is transparent?

Because the air in the bus moves with the vehicle, the flies in the air maintain the same speed and state as the air (vehicle), so the flies do not hit the rear glass when the car starts suddenly. If the fly dies, it also falls below.

The law of inertia, when a car starts, flies move backwards for a distance, just like people, and if they get close to the back glass, they will hit it.

If you die while driving, it will fall straight underneath, just like if you throw something up in a car, it won't hit the rear glass. It's still going to fall straight down.

Flies flying in mid-air inside the bus do not hit the rear glass because the flies and the bus have a speed of the same direction and size, and are relatively stationary. It's like when we're standing on the earth, we're standing still, the earth is spinning, but we're not hitting a building on the earth.

Relative rest means that two objects move in the same direction and at the same speed, and the position of the two objects with each other as reference objects does not change. For example, if a person sitting in a train uses a train as a reference, he sees that the position of the goods on the train to the train is unchanged, so the goods are relatively stationary to the train. If a tree or building on the ground is chosen as a reference, a person sees that the position of the goods on the building is constantly changing, so the goods move relative to the trees.

The moment the car starts, the flies from the seat will definitely go backwards, but not by much.

If the fly dies in the air, it will fall directly below the bus at a constant speed.

Note that when the car is moving, the flies and the air inside are one, and the air inside the car will still have a speed relative to the atmosphere outside.

This belongs to Newton's first law of inertia.

Naqiao Cangdong Royal Fly Lying on the Glass Demolition Inspection**:

The flies are lying on the glass high mold.

Summary. Not at first. Sometimes after exposure to the sun, it is caused by impurities in the production process.

You look at the point of what.

Hello, this should be caused by the presence of sand impurities in the glass material.

Not at first.

Not at first. Sometimes after exposure to the sun, it is caused by impurities in the production process.

It looks like fly droppings.

I thought fly poop was corroded.

Hello, this is impossible oh, thank you, teacher.

You're welcome, and have a great day!

The glass is very smooth, and the window panes are vertical, so many small animals can't walk on it, but flies can crawl around on it freely, and they won't fall off.

Flies have 6 legs, one with two claws on one foot, and a claw pad disc with fine hairs at the bottom of the claw. When flies move around the glass, they secrete a liquid from the tip of the hair, which has a strong adhesion. In addition, the fly's claw pads are concave along the edge and high in the middle, much like a hollow rubber cup, which can be sucked on glass.

The fly has more feet, and when they are together, the stronger the adhesion, and even if the glass is turned upside down, it will not fall off.

Flies can secrete an "antimicrobial active protein" that kills some of the germs they eat, while the other part of the germs are excreted. Therefore, flies eat dirty things with germs, and they do not get sick, but they spread the germs to humans, so flies are big pests.
