Potter turned around and saw that it was the employee who was monitoring the camera car in front of the screen who was making an exclamation, and his heart suddenly tensed, "What's wrong?" What do you see? ”

"I'm not sure, boss, come over and take a look, I think, I think we've found something amazing!" The man exclaimed excitedly. Pen "Fun" Pavilion www.biquge.info

Potter and his engineers hurriedly walked over, the 21-inch high-definition computer screen was dark green as a whole, with countless flickering white points of light on it, and there were four or five things that seemed to be white in front of them, and the light and shadow on it flickered, as if it was a dense night sky.

Because of the technical bottleneck, this kind of civilian camera car sees a scene similar to a night vision device before turning on the lights, the background color is dark green, there is no colorful color difference, and the rest is white and black.

The specific situation of the underground cave could not be seen from the screen, but these were all engineering experts present, and they still had some guesses:

"Flashing micaite? It looks beautiful. ”

"No, without the presence of a light source, how can mica stone glow? Even if there are light sources, they need to change the intensity of the light to flicker, I guess......"

"This is a firefly cave!" After all, the white chief engineer was well-informed, "I went to Te Anau to assist in the exploration of the fireworm caves, and this was what it looked like from the camera car!" ”

Hearing this, Potter gasped and said, "My God, we won't be so lucky, will we?" ”

As the name suggests, the firefly cave is a stone cave where firefly swarms gather, and there are generally underground karst caves, because such an environment is more humid and warm, suitable for fireflies to reproduce and survive.

This type of cave is a rarity in the world and is one of New Zealand's tourism trump cards, although glowworm caves are not particularly common in the country.

Potter continued: "I saw it when I went to Lake Taupo in the North Island and it was a dream! ”

Lake Taupo is New Zealand's largest lake, covering an area of 650 square kilometres, surrounded by complex terrain and diverse species.

However, the Te Anau Glowworm Cave is more famous, it was developed early, the natural conditions of the cave are peculiar, the tour arrangement and facilities are also more perfect, the mouth of the Te Anau Glowworm Cave is on the lake, and you must change to a small punt to enter the cave.

It is not difficult to determine whether this is a firefly cave or not, the camera car has a light source, and the reason why it was not opened before is because it is worried about disturbing some risk factors that may exist in the cave.

An engineer said anxiously, "So what are you waiting for?" Turn on the rover's lights and let's see what's down there! ”

Potter waved his hand and refused, "This is a place that humans have never touched, don't turn on the lights, who knows what unknown effects will be bringing?" There are also some ripple effects, and we can't guarantee it. ”

"Then how do you determine the identity of the cave below?"

"Of course we need to turn on the lights, but it's not up to us, call Mayor Wang and ask him to come over and decide." Potter said.

He is the most responsible thing to do, and there are several special rules for entering the glowworm cave to visit:

Stalactites and stalagmites will lose their color and damage their fragile structure by touching, so they must be cherished and never touched with their hands; The firefly cave must be quiet and not frightened and damage the ecological environment of the fireflies.

In addition, there is a total ban on smoking, and the use of cameras and video recorders is prohibited at all times, and the sudden appearance of light sources will affect the vitality of these insects.

Wang Bo came quickly after receiving the call, and on the way he also learned about the firefly caves in New Zealand.

Strictly speaking, this kind of cave should not be called a firefly cave, and those glowing insects in the cave are not fireflies, but a kind of glowing mushroom fly.

Fireflies are a general term for the Coleoptera fireflies, with about 2,000 species worldwide, distributed in tropical, subtropical and temperate regions, and there are probably more than 50 species in New Zealand.

The luminous mushroom fly is a species of the family Diptera Cycloschidae, and the individual is slightly larger than the firefly. However, they like to live in damp and dark caves, and they will glow like fireflies, making the dark cave roofs look like a starry night sky.

Therefore, the place where the luminous mushroom fly exists is often developed as a novel natural landscape as a tourist project.

The reason why it is called the firefly cave is that it is easy for visitors to understand, and secondly, it adds a romantic imagination to the tour.

After all, everyone knows what a firefly is, the mushroom fly is not good, and then the mushroom fly is very beautiful, but the word "fly" in the name is not good, it is easy to remind people of flies, for the sake of tourism, no one uses its real name to name the cave.

In addition, foreigners, especially Europeans and Americans, have a strong firefly plot, in the dead of night and cool breeze, they think that the most romantic is when they are in the place where the fireflies dance in the starry sky overhead.

Wang Bo wasn't sure if this was a firefly cave, because the lord's heart was not distracted to manage the location of the cave, he couldn't see the scene inside from the sand table, and he didn't even know that there was a cave on his territory.

Driving to a place two kilometers southeast of Lakeside Beach, Potter and others were waiting for him, and after he got out of the car, Potter asked directly: "Do you want to turn on the lights to make sure?" ”

Even if the cave is lit, it will not cause a mass death of mushroom flies, but it is uncertain, and Potter is more responsible, so he notified him first and let him, the owner, make the decision.

Wang Bo thought for a moment and asked, "If you don't turn on the lights, you won't be able to determine the identity of the cave below?" ”

The chief engineer said: "No, there is another way, that is, people go down in person, and the human eye can determine this, whether it is a firefly cave or not, you can determine it at a glance." ”

Wang Bo asked, "What is the judging standard?" ”

When he asked, he gave an answer, and Porter grabbed him and said, "Hey brother, are you crazy?" As for being so desperate? It's too risky! ”

Wang Bo smiled: "Don't worry, what danger can there be?" The most dangerous creatures I've encountered in New Zealand are bees. Okay, tell me, what are the judging criteria? ”

"There's no criterion, and when you see it, if it's a fireworm cave, your brain will tell you it's a firefly hole," said the chief engineer. ”

This answer was the same as no answer, and Lao Wang smiled: "Are you engaged in philosophy?" ”

Potter replied on behalf of the Chief Engineer, "That's true, King, if it's a fireworm cave, you'll understand when you see it, it's a fireworm hole!" ”

Wang Bo said: "Okay, I'll go down and see, who wants to go together?" ”

"Without a light source? It's insane! Mushroom flies like to live in places where there is no light, except for their own light, there is no light source, you can't see anything! Someone shouted in surprise. (To be continued.) )
