Dragonflies are small creatures that always attract someone's attention when doing their actions in the air and also look charming when perched in one location even though they look small when perched on top of each plant, but they are still considered great in every action when compared to insects other flying.

His mighty body model is like the body of someone who is athletic and good at moving, rotating, backward, forward with every movement or movement in the air while flying, making humans one of the models, in the creation of air transportation, namely helicopters

One has been inspired by this and was able to apply the model of its body and its prowess when it flew into an iron dragonfly which was powered by a machine capable of carrying a human into the air like a dragonfly.

Along with the sophistication of the world today, or it can be said that currently humans are getting smarter and increasingly understanding everything that can be imitated from all existing creatures and living side by side with humans, when experts explore dragonflies, many things are known, then they are discussed again about benefit to our nature. Then from the results that have been observed, we can take back the benefits and existence in our lives. But in this explanation, taking only a few special points, maybe we can take a little gist of his presence.

What is that? Let's take a look at some of the reviews below...

Dragonflies suddenly appear in your area

As for one of the philosophical words of our society here, namely Tiëp-tiep seusuatu, teuntèe na Tanda means that when something is going to happen there must be a cause and will show signs that show the truth of a situation that will happen

When an area is rarely visited by dragonflies, suddenly several dragonflies visit and tour the area, or make that location a new territory to continue their civilization or something else. So know that the region has some very good things for the region itself.

I have seen information about the characteristics of dragonflies, written in a biology handbook for grade 12 teachers, if it is concluded that this dragonfly is included as a signaling tool for humans.

Because the characteristics or behavior of dragonflies can be referred to as Alarms from Nature or as detectors of a situation in an area. So some people read the movement of dragonflies in a certain location as a natural way of knowing that an area or area is polluted or is still clean. So the presence of dragonflies is one of the bio-indicators of healthy waters and environments because they will breed in the water they choose. Scientifically or from the research results of insect experts say that, this dragonfly can only survive in clean water conditions, when they find such a location, it will be able to survive in that area for two years. Adult dragonflies that are ready to lay eggs will lay their eggs on the surface of the water and later their chicks will develop in the clean water for a certain time.

Then, whether his presence can be profitable? Of course, because his daily activities show something good and humans will know naturally without doing certain research on the nature around him. Then the advantages are very clear such as:

• Someone will know that the area has clean and healthy water without being mixed with bad pollution, if the adult dragonflies lay eggs in the water it means that they have detected that the standing water is very healthy for their children in the future. Though water health is also very important for human life itself. This is also said to be a natural cue or bio-indicator as already mentioned.

• Dragonfly larvae or their chicks will be born in the water they have chosen, of course this water has good potential so that the pups or larvae will also live in the water, when they become larvae they will continue to hunt every other animal, especially larva mosquite. Even though it is still a larva, it is also very brutal in hunting its prey until it becomes an adult dragonfly. Likewise, when it becomes an adult dragonfly it will also hunt every mosquito in a certain area. So he is said to be a good hunter, even though other animals will hunt him. In this case, humans can know that if an area has a lot of dragonflies, there are also many mosquitoes in the area, while mosquitoes are also something that humans don't like. This means that here is also one of nature's alarms which is very effective in indirectly informing the public about things that are not liked, even though mosquitoes or bio-indikator.

Not only that, if traced it turns out that its presence in a location can tell us that in a certain location there is something that humans don't like, even though what they do is that their daily routine demands something to find food as a necessity in life.

He will be present in a location that has a lot of plants why? Because he knows there are many insects that are his daily diet, while the signal for the plant farmers is as if he is telling you that there are many pests in this plant that thwart agricultural produce.

So based on the explanation above, it can be concluded that the presence of dragonflies in the human environment is a natural signal or a natural alarm as a bio-indicator, to be understood by humans.

See you again...
