Mainly operated by two children, Wei Yu and Wei Yuxi.

However, Li You needs to demonstrate it first.

Soon, Li You locked his target. A cicada on a tree trunk about four meters high.

As long as the cicada is at a height that can be reached by raising a bamboo pole, it can become a target.

Li You pointed at the target and said to the two children: "Did you see it? Just that one, let's catch that one. Watch me demonstrate it again."

"Okay."

The two children looked at it with wide eyes, and Xiao Yue, Zhang Ruier and others also looked expectantly.

Does this method work? You will have the answer soon.

Li You raised the bamboo pole and pointed the badminton racket-shaped device covered with spider webs at the top and slowly approached it.

Getting closer and closer, but the cicada never flew away.

When the distance was about 20 centimeters, Li You quickly pressed down, and the badminton racket-shaped device successfully covered Cicada.

Success.

After being covered in this way, the possibility of Zhizhi being able to break free is very small.

Unless the spider web is damaged after being used for a long time, even if it covers the cicada, it is very likely that the cicada will be able to break free and fly away during the process of taking it off.

But now that I have just started using it, I know that the possibility of breaking free is very small.

Li You lowered the bamboo pole, and you could see that the cicada had been stuck by the spider web. Although he was struggling, it was to no avail.

While struggling, no sound was heard, indicating that this was a female cicada.

If it were a male cicada, it would definitely make a sharp cry while struggling.

Only male cicadas will sing, but female cicadas will not.

Because the female cicada's body structure is incomplete and has no eardrum, she cannot make sounds.

There is a sound generator structure at the base of the abdomen of the male cicada. It is like a large drum covered with a layer of eardrum.

The eardrum is vibrated to produce sound.

At the same time, because the cicada's vocal muscles can stretch and contract about 10,000 times per second, and there is an empty space between the cover plate and the eardrum, it can play a resonance role.

Therefore, the chirping sound is very loud.

The sound made by its small body is louder than the sounds made by many animals whose bodies are many times larger than it.

It is precisely because they are so loud that many people think they are summer noises.

I was really hooked after seeing this. The two children, Wei Yu and Wei Yuxi, were very excited and clapped their hands in joy.

Xiao Yue, Zhang Ruier and others also had bright eyes and really caught it.

This tool can really catch cicadas.

And it was successful the first time. This shows that the success rate is really high.

Who came up with this tool first? Quite clever!

With this tool, catching cicadas is easy.

It was successful, and Li You was very happy. After more than ten years, I used this thing to catch cicadas again, and it felt pretty good.

Everything seems to have not gone far yet.

Then he flattened the bamboo pole and signaled Wei Yu and Wei Yuxi, two children, to step forward and take the cicada off.

Wei Yu got closer, stepped forward, grabbed Zhi Zhi, who was still struggling, and pulled it off with a little force.

Wei Yu was very excited when he finally caught the cicada in his hand. He tossed it over and over for a while, and then said, "Uncle Li You, why doesn't it bark?"

Li You smiled and said: "Because it is a female cicada. Female cicadas cannot scream, only male cicadas can."

Wei Yu nodded and said he understood. But after a while, he asked again: "Why? Why doesn't the female cicada sing?"

Li You added: "Because the female cicada does not have a sound generator. Look at its abdomen. The male cicada's sound generator is there, but the female cicada does not."

Wei Yu turned over the cicada in his hand and looked at his abdomen, but he couldn't see anything interesting.

Li You said: "This way. Let's catch another male cicada later and compare it. Then we can see the difference."

Wei Yu said excitedly: "Okay, then I'll catch you."

Li You nodded and smiled: "Okay."

Wei Yu gave the cicada in his hand to Wei Yuxi and said, "Take it first. I'll catch a male cicada."

"Okay."

Wei Yuxi took the cicada.

Wei Yu picked up the bamboo pole and started looking for the target on the tree.

Xiao Yue, Zhang Ruier and everyone else looked at it with interest.

"By the way, boss. Can I use this to catch dragonflies?" Xiao Yue asked Li Youdao.

Li You nodded, "Yes. But the success rate is very low. The dragonfly's response is much faster than that of the cicada, and it is much more vigilant. It may not be possible to succeed even if it is caught ten times."

Xiao Yue nodded, "It is true that dragonflies are not easy to catch. Of course, dragonflies are beneficial insects, so it is best not to catch them."

Li You said: "Indeed. Dragonflies are the spirits of summer. We must love and protect them."

Xiao Yue said: "It is indeed."

At this time, Wei Yu had already chosen his target. He was imitating Li You and slowly approaching the badminton racket-shaped device.

In the end, success will cover the cicada.

Got it!

Wei Yu was very happy. He took the bamboo pole down.

This time, while the cicada kept struggling, it also made a sharp sound.

This is a male cicada.

Li You's eyes lit up. He said he wanted to catch a bear, but he actually caught it.

Very good.

"Uncle Li You, this can only scream, this is a male cicada." Wei Yu said excitedly.

Li You nodded, "Indeed."

After putting down the bamboo pole, he grabbed Zhizhi again.

After catching it, it was still chirping.

"Xiaoxi, bring me the female cicada just now." Wei Yu said to Wei Yuxi.

Wei Yuxi handed the cicada in her hand to Wei Yu.

Wei Yu took it.

Then, with each hand, they turned the cicadas over. This comparison revealed that the abdominal structures of the two cicadas were completely different.

The most obvious difference is that there is a pair of semicircular structures in the middle of the male cicada's abdomen.

And does the female know?

Li You pointed at the semicircular structure in the middle of the male cicada's abdomen and said, "This is their sound generator. Their calls come from here."

Wei Yu and Wei Yuxi both nodded and said they understood.

This time the impression was so profound that they will never forget it in their lifetime.

Even among the guests, some suddenly said, "So that's it."

Obviously, they did not understand the difference between male and female cicadas before.

This chapter is not over yet, please click on the next page to continue reading!

Of course, this is normal. A large number of adults actually don’t know that only the male cicada can sing.

They usually don’t pay attention to these things, nor do they understand them, so they don’t know that it’s normal.

They have mastered new knowledge. Wei Yu and Wei Yuxi are both very happy.

Wei Ping's family was also very happy.

Next, the cicada arrests continue.

It’s time for Wei Yuxi to take action.

After a while of manipulation, Wei Yuxi also successfully caught a cicada.

"Xiaoxi, I want to try it too. Can you let me try it once?" Xiao Yue said to Wei Yuxi.

"Okay!"

Wei Yuxi brought the bamboo pole to Xiao Yue.
