How do mosquitoes find you?

In the dark, mosquitoes also don't see people, but how do mosquitoes discover you? It turns out that it is not the sound of your breathing, nor the smell of yours, nor the mosquitoes and bumps, but the mosquitoes are sensitive to the heat from your body.

Like all warm-blooded animals, human body temperature is relatively constant, which means that the heat generated by the body and the heat emitted are basically equal. The heat dissipation of the human body is mainly the radiant heat of the skin and the heat of evaporation of the sweat glands, followed by the partial heat of the lungs through the breathing. The radiant heat of warm-blooded animals is actually an infrared ray, also known as infrared light, which is a kind of light that is invisible to the naked eye, but has a significant thermal effect.

In nature, many animals have structures that can receive infrared information. The infrared detector of the female mosquito is its antennae, which is ring-shaped. When the female mosquitoes feed, they constantly turn a pair of tentacles. When the radiant heat received by the two antennae is the same, it is known that the warm-blooded animal that can be smashed is in front, and the female mosquitoes fly toward the target. According to the principle that the more radiant heat is received from the heat source, the mosquito can accurately detect the orientation of the radiant heat source.

There are some snakes in the snakes, such as the rattlesnake that can make a sound when the tail is swinging. It is widely distributed in China's pythons, beautiful bamboo leaves, green snakes, etc. There is a dimple between the eyes and the nostrils, called the cheeks, which is extremely sensitive. Infrared sensation. Putting a blindfolded rattlesnake under the two bulbs, the rattlesnake did not respond when the bulb was not lit, and it seemed very quiet. When one of the bulbs was turned on, the rattlesnake immediately opened its mouth and looked very excited. And ignore the light bulb that is not bright.

The infrared sensor of the python is on the front and the lips of the head, called the lip socket. The tail of the infrared susceptor of the deep sea squid is called the thermal eye. In addition, chickens, bed bugs, ants and other animals have the ability to feel infrared radiation.
