With the onset of heat, the ubiquitous problems return again flies. They penetrate everywhere and cause a certain discomfort to people. Natural dexterity faceted eyes, allowing you to see 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 excites not only children, but also adults. For this, nature has endowed it with some features.
What surface can it sit on?
The fly holds easily on any surface. It can be horizontal, vertical, sheer. It does not slip even from glass and other smooth surfaces. If we consider the option of how the fly hangs on the ceiling with wallpaper or other decoration, we can assume the coating is not ideal.
For small paws of an insect, any, even a very small tubercle becomes an excellent way to fix. But it doesn’t even slide from the same surface, but made of perfectly even glass.
Why the fly doesn’t fall from the ceiling
To reveal this secret is very simple if you look at the structure of her legs through a microscope. The enlarged shooting will show the following features:
- The presence of 2 claws. They allow her to grab onto 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 a small pillow. On the outside of it, the pads are 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. It is it that allows individuals to hang above the ground and not fall. Sticky mixture is allocated exactly such an amount that it was enough to keep an individual, but not to impede its movement.
Interesting!
An interesting experiment was conducted by researchers. They covered the insects with special filter paper, which quickly and effectively absorbs any fat. As a result, the substance secreted by the flies was quickly absorbed, and the flies could not gain a foothold.
Soft landing: detailed analysis
A better understanding of how landing occurs and why the 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, which allow her to be securely attached to any materials.
Interesting!
The insect does not fly forward, as many others gather it, but back. Therefore, to kill him, you should aim a little behind.
A fly sits on the ceiling from a loop or from 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 prints the fly.
What macro photography showed
An amazing discovery was given by a macro shot of observing the behavior of a fly. The insect does not push off the ceiling to take off. It just relaxes, releases the surface and falls down. Then the fly swiftly flips downside down, spreads its wings and already flies normally.
