What do flies rely on to sense things around them?

Flies do not have noses, and the olfactory organ is a pair of antennae on the head, only millimeters long, and inside is a small cavity that communicates with the outside world, and there are many olfactory cells in the small cavity, which has an amazing sense of smell and can find very faint smells at a great distance. Based on this ability, people have made a very sensitive small electronic "gas analyzer". It also has a peculiar and delicate compound eye, with a vision range of 350 degrees, even the back of the head can be seen, and ultraviolet light can be seen.

You can see things in a flash in seconds. People imitate its compound eyes to make "compound eye lenses", "fly's eye cameras, can take 1329 identical pictures at a time". The fly has a pair of wings behind its wings, which vibrate at a frequency of 330 times per second when flying, and can freely do various forms of flight while maintaining the same course.

Its flying skills are unmatched by even the most advanced aircraft available today. Based on this function of flies, people developed "vibrating gyroscopes" and began to design a high-efficiency "fly aircraft". Everyone knows that flies like to eat rotten food, but there is a fly in the Americas that loves oil.

This bizarre phenomenon has caused scientists.

interest. After research, it was found that the fly has a special cell in its gastrointestinal tract that obtains the nutrients it needs from the waxy substance of petroleum. Because of its special function, scientists use this bacterium to ferment and dewax the oil, thereby improving the quality of the oil.

The way flies perceive their surroundings includes relying on senses such as eyes, smell, and touch.

1.Eyes: The eyes of flies are compound eyes that are made up of many small eyes that can see different things in multiple directions at the same time, allowing them to better perceive their surroundings.

2.Sense of smell: Flies have a lot of sensory hairs on their antennae, which can sense smells and then judge information such as food and danger.

3.Touch: Flies also have many sensory cells on their antennae, which can sense information such as air flow, temperature, humidity, etc., to help them judge whether there are obstacles around them, whether there is danger, etc.

In conclusion, flies are able to perceive changes in their surroundings and thus adapt to their living environment.

It senses air flow and pressure changes by the fluff on the body.

The fly is perceived by its compound eyes.

Mosquitoes have antennae and bristles on their heads and legs, and they are sensitive to humidity, temperature, and sweat, so they often bite people who sweat and do not bathe. Children's **delicate, metabolism is lively, **pores volatilize sweat quickly, and they are often bitten by mosquitoes. Also, mosquitoes are very fond of low light, and if you wear a black outfit, it is just right for the mosquito's visual habits.

However, mosquitoes are sensitive to strong air currents, and it is difficult for mosquitoes to approach you in the summer when you shake your fan to cool off.

It may be that you have some kind of fly smell that you like...

How do insects breathe? The insect has a row of small holes on each side of the chest and abdomen, called valves, which are the respiratory organs of the insect. Insects tug on the chest. This is true for flies and mosquitoes.

Questioner's evaluation of the answer:

You know the rest of the estimates, I'll just say the special.

The snake's tongue is special, it is bifurcated, and it keeps spitting out, which helps to collect signal molecules, and the cells on the tongue are special, to put it bluntly, it can taste the smell, that is, it already knows whether you are good or not before eating you.

In addition, there are two small depressions next to the nose, which are used to detect temperature changes, and heat-sensitive cells are said to be able to sense temperature changes by 1/1000.

According to the tests of experts, the eyes of flies are composed of tens of thousands of small eyes in the form of a grid, and the positioning is very accurate, and it can distinguish speed and direction, etc., and the radar is based on this invention. Mosquitoes, on the other hand, perceive things through their antennae to perceive the infrared rays around them, which is naturally slower.

Not just on the eyes, but also on the muscles under the flies' own wings (there are still. It is stronger than mosquitoes, and it flies more quickly and agilely.

Flies have bigger eyes than mosquitoes!

The fly's eyes are very bright, and what its eyes see is scattered and combined.

Flies rely on heat induction to discern directions and things, and people are alive because of heat transfer, and they won't be dead anymore!

Flies can be active at night, and their activity is affected by light and temperature, and they will move at lights when the temperature is enough at night.

Flies have obvious phototaxis, and fly to **bright ones, so they like to move in places with lights during the day or at night, and in dark places or at night, they will rest on the ceiling or hanging ropes and walls.

The activity of flies is greatly affected by temperature. It can only crawl at 4 7 o'clock, fly at 10 15 o'clock, feed, mate, and lay eggs at 20 o'clock or more, it is especially active at 30 35 o'clock, 35 40 stops its activity due to overheating, and dies at 45 47 o'clock.

Flies are insects that are frequently active during the day and have obvious phototaxis. At night, it is stationary. Most insects have phototaxis and do not move in the dark, and flies are no exception, flies rely on vision to judge things, and they cannot see at night, although they are now very bright everywhere at night, but the habits that have been formed for a long time are not so easy to change.

It's always been possible....Especially when you turn off the lights and play with your phone, it will climb on your phone...It's annoying....

No, the fly sleeps at night, because it also needs light to see, and if the light is on, it will fly over.

Flies are rarely active at night, and generally stay on power lines or places it deems appropriate, and spraying them with fly killers is very effective.

No, if the light is on, it will not be if the light is not on, and it will not be on its stomach at night.

Yes, there is light, there is light, there is light, there is light, there is light.

Yes, there are often flies around at night.

Now that the lights are so bright, flies will think it's daytime.

If you have something to eat at home, or if you have a window that always opens and flies in.

Generally, no, I will find a place to lie on my stomach.

Flies are inactive after you turn off the lights.

There is a bright light and the temperature is high.

The humidity will be high. Ventilation, drying will not.

Yes, the environment is not good and it has become worse

This should be okay.,Otherwise, why do you have to put away the leftovers at night?。。。
