Dragonflies rely on their tails to smell!

Dear users, your question must be first me, and then you dragonfly without ears.

Dragonflies are the insects with the most eyes in the world. Dragonfly's eyes are large and bulging, taking up most of the head, and dragonfly's eyes are typical compound eyes.

And each eye has countless "small eyes", these "small eyes" are connected to photoreceptor cells and nerves, when the object moves in front of the compound eye, each "small eye" in turn produces a reaction, after processing can determine the speed of the target object. This makes them masters of insect catchers in the insect world.

Dragonflies can see things up and down, left and right, in all directions, in all directions. It is because the dragonfly's eyes are compound eyes, and his eyes are not covered, 360 degrees, and he can see any object.

Dragonflies have very sensitive vision, and most of their heads are occupied by a pair of large compound eyes. Each compound eye is made up of many small eyes, ranging from 10 to 30,000 in number. Each eye is a small camera, and the surrounding objects are constantly ingested to form images.

It can see things up to 6 meters. The whole compound eye is spherical, and its curved surface can take care of all directions, and the dragonfly's large head can rotate freely, so that the dragonfly's field of vision is very wide. When an object moves in front of the compound eye, each small eye reacts in turn, and after processing, the speed of the target object can be determined according to the image and time that appears in the small eye continuously.
