Chapter 157 Goodbye Firefly

Professor Pan looked around: "Actually, the environment of this place is really good, there should be fireflies."

The fireflies that hide in the dense grass during the day will start to move around at sunset.Everyone walked in the woods for more than an hour, and it was almost seven o'clock, and the sunset time of this day was a quarter past seven.

Since Professor Pan said so, everyone began to set up cameras suitable for night photography here.

The sun had just set a little bit, and the sound of frogs in the mountains began to rise and fall one after another.

Except for a few species of birds, most birds suffer from night blindness. Therefore, from this point in time, birds return to their nests, and many amphibians and insects threatened by birds become active.

This point of knowledge tortured Qi Lanting a lot. In order to prevent the invisible insects from approaching him in the dark, he sprayed a large dose of insect repellent spray on his body.

"Why did I promise you to come here to be tortured! I should have gone to dance with Han Cong to watch the young lady who is a trainee!" Qi Lanting wailed.

Li Chengxin pinched his nose: "Lanting, you smell too much! The fireflies will be smoked away by you."

Professor Pan also looked at Qi Lanting with discriminatory eyes. He pointed to an open space in the distance: "Qi Lanting, go there and wait for us."

Qi Lanting looked over there. There was unknown fear in the poorly lit mountain forest, so Qi Lanting shook his head like a rattle: "Zicheng, come with me, it's so scary over there!"

Li Chengxin smiled: "I've never seen you so timid before. Didn't Zhang Badao also shoot night scenes in the woods?"

"That's different! Unless you also set up a high-power searchlight for me!"

"Okay," Li Chengxin helplessly patted Brother Xiaoyong on the shoulder, "Then I'll leave it to you."

As he said that, he took two folding chairs and sat with Qi Lanting a little far away. Even so, in order not to be blinded by the strong smell of insect repellent water on Qi Lanting's body, he still stayed far away from him.

According to Professor Pan, within half an hour after the daylight completely fades away, it will be the time period when the fireflies glow most brightly, and all they have to do is wait.

Sure enough, after a while, Brother Xiaoyong found a bright spot in the grass near the puddle.

"Right here, there are two places, twinkling and twinkling!"

When Li Chengxin heard about it, he dropped Qi Lanting and ran over there carefully, only to find that there was also a faint light not far from him.

At first, the spot of light was still hidden under the wide blades of grass, only slightly visible in the darkness.Gradually, the light spots moved out from under the grass blades, and more and more light spots flickered.

Gradually, several yellow-green light spots began to rise up, and the light covered by the firefly's elytra was fully revealed, and began to dance around in a flash.

【so beautiful! 】

【Too beautiful……】

[I saw a firefly on the side of the road some time ago, and I watched it like this for a long time]

Without seeing the figure of the firefly, Qi Lanting's fear of insects is not so serious.A spot of light flew towards him, Qi Lanting gracefully stretched out his hand to catch the spot of light, but the spot of light just got closer and then turned and flew away in another direction.

Insect repellents are indeed a heinous crime!
Compared with several young people who were immersed in the beauty of fireflies, Professor Pan took out his stopwatch in a more professional manner.

Most of the domestic firefly species are edge-brown firefly, black firefly, dome firefly and yellow edge firefly. The tail lights of each firefly have different flashing frequencies.

"The flashing frequency of these fireflies is about once every two seconds. According to this cycle, the type of fireflies here should be the brown-edged and black fireflies. The yellow-edged firefly has the longest light duration, and it only goes out every four seconds. "

The light-emitting organs of fireflies grow from the abdomen to the tail region. In this region, luciferase formed from the protein eaten by firefly larvae is contained.The chemical reaction between luciferase and oxygen in the air forms the light on the firefly's abdomen.

Unlike the light emitted by electric lamps, this light does not generate heat. This form of organic light is also used in the latest organic EL light-emitting electronic boards, that is, curved screen or folding screen TVs, mobile phones and other electronic products.

"The glow of fireflies is actually a form of courtship. The male that glows while flying is the male, and it will fly like this while looking for the female that stays on the plant and glows."

"Fireflies make no sound at all when they fly. If they make buzzing noises like mosquitoes and flies, it might not be so wonderful." Qi Lanting couldn't get close to the fireflies, so he curled up on a folding chair and admired the flying fireflies from a distance. .

Following a descending male firefly, the camera captures another firefly on a blade of grass.

"That one should be the female. Let's see if the male fireflies will stop near there."

For a moment, all the people present stopped sighing at the beautiful scenery, held their breath, and stared at the light spot flying towards the female firefly.

Sure enough, not long after, the two fireflies stopped together, one on each leaf, facing each other and began to send out flashing light signals.

First, male fireflies speed up their flashes to once a second to attract the female's attention.

"Theoretically, if the female accepts the male's courtship, its flickering frequency will be adjusted to be the same as the male's." Professor Pan continued to explain.

"If you like it, it will flash at the same frequency. It's so fun." Both Li Chengxin and Brother Xiaoyong have seen fireflies in the countryside, but they have never observed them in this way.

"It's called 'Your light is mine'! ()" Qi Lanting joked.

Just waiting like this, after a few minutes, the flickering rhythm of the two fireflies actually closed.

"That's all for this pair?"

"Yes!"

"Great!"

After that, the two fireflies will stick their tails together tightly. A few days later, the female firefly will lay 50 eggs with a diameter of about 0.6 mm on the moss near the puddle, pond or stream.

The adults of fireflies can only live for about a week, so in the limited and beautiful time, they have to race against time to produce offspring.

After everyone recovered from observing the successful pairing scene, more and more fireflies appeared in the air nearby, and there were also many light spots on the grass leaves and plants in the lower place.

Not far away, there was even a scene called a "courtship group" in which multiple males surrounded a female to court her.

"It's so beautiful." Qi Lanting murmured, "I really hope that the top floor of Geyue Entertainment can also see such a beautiful scenery!"

"Suddenly I feel love. Firefly and Xinchi must be a good match!" Li Chengxin remembered his wish to take Yingying to see Xinchi.
