: Bees (the picture comes from the Internet)

May Day has just ended. Today, Zeyou Science and Technology will take you to have a deeper understanding of our natural model worker-bees.

The bee, a hymenopteran insect, is a social animal with a clear division of labor. I am afraid that many small partners love and "hate" bees, love their diligence and bravery, love the delicious honey they brew, and at the same time leave a "childhood shadow" on bee needles ".

Today, Xiao Bian will use ZEM15 desktop scanning electron microscope of Ze You Technology to take everyone to explore it in depth.

Strayed into the Room First of all, let's see how much hair is on this fluffy little guy...

is worthy of being a "fluffy" little guy... The whole body of the bee is covered with fluff, even the wings are also hair. So what's the use of these hairs?

It turns out that the dense fluff on the bees makes them extremely sensitive to electric fields and can sense the coming heavy rain in time to avoid harm. In addition, the bee fluff in friction with the hive, will produce a large number of electric charges, the electric field shock generated by this charge for the bees in the dark hive positioning can also play an auxiliary role.

Since it is an insect, how can we not look at its compound eyes.

ZEM15 scanning electron microscope: compound eye of bee

compound eye of bee consists of about 5000 small eyes, each small eye has a set of light collection system and photosensitive system, so it has very developed vision. In addition, compound eyes will also make bees have a wider field of vision, a wider spectral perception range and a more sensitive ability to capture moving objects.

Friends familiar with bees may all know that bees rely on strong thighs to carry pollen. Therefore, the thighs of bees are also called powder-carrying feet.

can be seen in the figure, the bee's hind foot joint is extremely enlarged, with long and dense fluff around it. when the bee shuttles through the flowers to collect pollen and nectar, the fluffy foot is covered with pollen. then, the pollen is combed by the "pollen comb" on the hindfoot and collected in the "pollen basket. Use honey to fix the pollen into a ball.

Let's take a look at the "childhood shadow" of our friends-the bee needle.

bee needle, also called stinger, is the self-defense organ of bees, when bees feel threatened, they use it to stab enemies. In the picture, we can see that the bee needle is surrounded by "barbs" structure, so that it is difficult to pull out after plunging into the enemy's body. If it is forcibly pulled out, it will also damage the internal organs of the bees and even die. Therefore, the bee needle is also a kind of "suicide" weapon, bees do not feel life is threatened, it is not easy to use.

The above research was completed by ZEM15 Desktop Scanning Electron Microscope independently developed by Zeyu Technology.

The electron optical system, detector, circuit control system, signal acquisition system and operating software of the ZEM15 scanning electron mirror are all independently developed by Zeyou Technology. Specially developed electronic optical system design, so that the picture has a higher signal-to-noise ratio and contrast. With a high signal acquisition bandwidth, can be in the video frame rate of high-quality smooth display samples. All operations can be done with just a mouse, without the need for a diaphragm to medium complex steps. The host integrated high-voltage and control system is a small desktop scanning electron mirror on the market at present, which is easy to move and does not require special environment for installation.
