As a fly sits and clings to the ceiling
Content
With the onset of heat, the problems of the omnipresent come back. flies. They penetrate everywhere and bring some discomfort to people. Natural agility, faceted eyes, allowing to see at 360 degrees, and many other features, allow the insect to save its life and instantly respond to danger. The question of how a fly sits on the ceiling concerns not only children, but also adults. For this, nature has endowed it with some features.
What surface can sit on
The fly with ease keeps on any surface. It can be horizontal, vertical, steep. It does not even slip from glass and other smooth surfaces. If we consider the option of how the fly keeps on the ceiling with wallpaper or other trim, we can assume that the coating is not ideal.
For small insect paws, any, even a very small tubercle becomes an excellent way to consolidate. But it does not even slip from the same surface, but made of perfectly smooth glass.
Why the fly does not fall from the ceiling
To reveal this secret is very simple, if you look at the structure of her paws through a microscope. Enlarged shooting will show the following features:
- The presence of 2 claws. They allow her to grasp the microscopic protrusions and hold for a long time.
- Suckers They are located at the base of the claws. The suction cup is made in the form of small pads. On the outer side of the pads overgrown with ordinary hairs, on the other hand there are very small disc-shaped suckers on the hairs.
- Sticky substance. At the end of the forelegs during landing, a special substance is released. It is sticky and greasy.That it allows individuals to hang above the ground and not fall. Adhesive mixture is allocated exactly the amount that was enough to keep the individual, but not hinder its movement.
Interesting!
An interesting experience was conducted by researchers. They insect bed special filtering paper that quickly and effectively absorbs any fat. As a result, the substance released by flies was quickly absorbed, and flies could not be fixed.
Soft landing: detailed analysis
To give a greater idea of how the landing takes place and why a fall does not occur, will allow consideration of the behavior of the individual at the time of landing. During the flight, she easily makes various complex pirouettes that allow her to fasten securely on any materials.
Interesting!
The insect takes off not forward, as many others gather it, but back. Therefore, to kill him, you should aim a little behind.
The fly sits on the ceiling with a loop or a coup. As a result, it transfers the center of gravity to the front and is glued to the ceiling with its paws. The rest of the body catches up with the front and even more tightly seals the fly.
What macro photography showed
An amazing discovery was given by macro photography of monitoring the behavior of the fly. The insect does not push off from the ceiling to take off. It simply relaxes, releases the surface and falls down. Then the fly rapidly turns down the belly, spreads its wings and flying normally.
