Mention of "cockroaches", may be unfamiliar to everyone, but if you talk about "thin waist bees", you should be more impressed. This bee is mostly yellow and black, small in size, with a particularly thin waist, and is particularly light in flight. In fact, the cockroach is a general term for a type of wasp dominated by thin-waisted bees, and it is usually called earth bees, midges, pulu or slender-waisted bees.
This type of bee is especially common in the countryside, they do not like to live in groups like other bees, but like to walk independently, and there is no fixed nest, only after "marriage" can you see the crabs in and out of the pair.

The nest of the grasshopper is very peculiar, mostly made of soft mud, and the mud is not the ready-made mud that the grasshoppers have brought back from elsewhere, but mostly the mud that they have brought back to the water on the spot. Its nests are often built on trees, wall skins, electric poles or other buildings, some directly with the help of bamboo pipes, tree holes or some other hollow wood. The nest is not large, mostly in the shape of a pot, and the opening of the hole is at the lid of the pot, so people often call its nest a pot hive, a mud beehive and so on.
Although the nests of the grasshoppers are made of mud, after they are so upside down, they instantly raise their value and become a good medicine for healing and saving people.
I remember when I was a child, there was a child next door who had malignant laryngitis, phlegm cough could not be coughed up, cough could not be stopped, so the next door aunt was full of villages to find these mud honeycombs, and then took it home and grinded it to her children to boil medicine to drink, remember that after drinking a few times, her child's cough was shocked.
So for a time, the mud hive was rumored to be a miracle medicine for cough and anti-inflammatory, so the people in the village collected it one after another, just in case of emergency, and therefore, for a time, there was hardly a complete mud honeycomb in the village, which was very peculiar.
And it's not just its honeycomb that's strange, in fact, the worm itself is a legend. Because there is such a terrible legend in it.
I remember listening to the old people in the village when I was a child, this slender-waisted bee (cockroach) only had male bees and no female bees. However, we also know that everything in this heaven and earth pays attention to the balance of yin and yang, there are males and no females, whether they can survive is not to say for the time being, the light of this inheritance and the continuation of heirs is a big problem, if the legend is true. Well, I think the slender-waisted bee has long since become extinct from this earth. But they are still alive and well, how can this be explained?
Originally, it was said that slender-waisted bees themselves would not give birth, but in order to prolong their offspring, they would catch other people's children back (the most common catches are borers, corn borers and other euphrods), and then put them in their nests and feed them as their own children. However, we know that other people's children will naturally look like others when they grow up, so how can they be like it? Will it change from eun to bee?
According to legend, this slender-waisted bee mastered a set of mantras, and as long as it chanted this mantra for seven hundred and forty-nine days, the other person's child would grow up to look like itself. What is a spell? In fact, there is nothing special about it, that is, it is to keep shouting at those bugs, "Like me, like me, like me!" "Just keep shouting, shouting for forty-nine days, and these borers will grow up to look like worms."
How it is yin and yang, and how it is a mantra, it sounds very evil. I think there must be friends who will say that this is completely false information that I made up to earn eyeballs. First of all, this is certainly not made up by me, this statement has actually been passed down in China for more than 2,000 years, and the "Book of Poetry, Xiaoya Xiaowan" has clouds:
The borer has a son, and the borer bears it.
The meaning of this sentence is that the little larvae of the borer are taken away by the grasshopper, and it feeds the larvae of the borer as its own child.
Also holding the same theory was the Western Han scholar Yang Xiong, and his statement was more vivid and accurate, he said in the "Fa Yan Xue Xing":
The son of the borer dies and every time the frog wins, the day of the blessing: like me, like me, long time Xiao Zhiyi.
Presumably, the moth wins to catch the larvae of the borer and shouts at it all day long, "Like me, like me", and over time, the borer really looks like the borer wins.
Of course, saying that the slender-waisted bee (cockroach wins) catches the larvae of other insects and takes them back to feed, and then through the way of "prayer", let other people's children look like themselves, this kind of story coaxes children to be OK, for us adults, we know that this statement is distorted. So, what are the facts?
In fact, it is true that the slender-waisted bee catches the borer, but it is not caught back for inheritance or raising children to prevent aging, and the situation is just the opposite, it is used to eat. It turns out that the slender-waisted bee is a parasitic bee, and it is not only male bees and no female bees, and they catch the larvae of the borer, on the one hand, for their own enjoyment, and on the other hand, for laying eggs.
When they catch the borer larvae, the female will use its tail needle to stab these poor bugs, and at the same time, it will inject eggs into the body of the borer larvae, leaving the borer comatose in a semi-dead state, and eventually the food that becomes the egg is preserved. After a month, the eggs will grow into adults, at which point the borer will be eaten only by the hatched larvae. In fact, this is the real reason why slender-waisted bees catch borer larvae.
In fact, it was Tao Hongjing, a famous medical scientist during China's Southern Dynasty, who revealed the truth that the borers were hunted as "righteous sons" to raise them, and he felt that the "heavenly silkworm change" breeding process wastle, which was very ridiculous and particularly absurd. Therefore, after in-depth research, he finally revealed the truth of the facts.
However, it is only that the circulation of the Book of Verses is relatively widespread, so that for thousands of years, there have always been people who believe that the slender-waisted bee does not have a female bee, but adopts the children of others to pass on the generations.
In fact, there are more than these strange things in the body of cockroach win, because the cockroach win is an agricultural beneficial insect, which mainly feeds on the larvae of rice borer, longitudinal leaf borer, corn borer, cotton bollworm and other lepidoptera insects. Therefore, farmers in some places often put some bamboo pipes that the shrimp win likes to build a nest in the crop field, in order to attract some cockroaches to build nests and lay eggs here to help them eliminate the pests in the crop field, and this method has also achieved a certain preventive effect.
Although the sting wins a poisonous thorn that the stinger cannot bear, it does not actively attack humans. At the same time, it is also an agricultural beneficial insect, which often helps farmers eliminate other pests in their crops.
For thousands of years, people's understanding of the win of the cockroach has also been strengthening, although at the beginning people had a misunderstanding of its reproductive method, but in the general environment at that time, "the borer has a child, and the worm bears it." Teach Erzi, like a grain. This concept still gives a lot of enlightenment to future generations, and the meticulous, skeptical and specialized attitude of Mr. Tao Hongjing, a medical scientist of the Southern Dynasty, is more worthy of learning from each of us. Of course, at the same time, we must also learn from the spirit of obscurity and selfless dedication of The Fly Win.
