Cute little elf--Bee

In life, some children as soon as the mention of bees, immediately think of bees will sting, quite annoying. In fact, bees generally do not easily sting, stinging is its self-defense, it is the maintenance of life to make a kind of instinctive response. When a bee encounters aggression, it will stick the poisonous needle in its tail into the body of the other party and release the venom. If someone inadvertently killed a bee, will also attract a swarm of bees to follow and be stung, this is the bee in the retaliation; bees tail end of the needle is a weapon of self-defense, it is connected to the body of the venomous glands, bees in the use of its poisonous needles after the body will be torn and die.

In fact, bees are a kind of cute little elves, with its hard work to win people's true love. There is a poem in Tang Dynasty which praises bees in this way: "No matter the flat land and the tip of the mountain, the infinite scenery is occupied. After picking white flowers to make honey, for whom they work hard and for whom they are sweet!" Bees have their own way of life, with a clear and precise division of labor. The worker bees are responsible for collecting honey, and they go out every day to look for nectar, bring it back, and go out again. Their bodies are electrically charged, creating a bio-magnetic field that allows them to determine the direction of their journey out and back in accordance with the magnetic field. Worker bees can also judge their direction by the sun, so no matter how far they fly, they can always find their way home.

Interestingly, the worker bees also "dance" in the air according to various shapes to exchange information with their companions. When the bees in charge of "detective" found a source of honey, or outside the nectar to return, will be in the hive over the joy of flying a dance, flying out of the figure to tell their companions what direction of the flowers. They use the sun as a reference to indicate the direction. They use the sun as a reference to indicate direction and distance. The distance is indicated by the number of circles, tens of meters, hundreds of meters or thousands of meters, all have a fixed number of circles. What's even more amazing is that bees from different regions have different dance languages. For example, bees in Italy dance the "sickle dance".

The eyes of the bee play a key role in the honeydew. In order to be able to see the surrounding environment, bees grow many compound eyes, about 5 million, the so-called compound eyes is composed of many tiny eyes, each small eye can see a small range, and then so many small eyes to see the combination of objects, can form a large range. Although the bee has many compound eyes, because of its small body, the eyes are even smaller.

It seems that even though bees are tiny, their impact and contribution to humanity is not small at all, so we need to protect them.
