Dragonflies are always looking for sources of water that are clean and free of chemicals.

Hi hive lovers ...
On this occasion I will try to discuss dragonflies, coincidentally, I found an object of dragonflies that was standing leisurely on a tree branch, the moment was not wasted, I just capture it with my cellphone camera.

Speaking of dragonflies, I think we all know a type of insect called a dragonfly, what more children are certainly very familiar with this type of insect, and we also know the origin of the creation of a helicopter is an adoption of dragonflies.

Perhaps many of us do not know the benefits of dragonflies for the environment or humans, the role of
odonata, or what we know as dragonflies, has a river as a bio-indicator of our environment or the area where humans live, based on the first thing, dragonflies can be used as indicators of water, why do I say that, because dragonflies' habitats always lay eggs in water and then become nymphs or insects that live in water, so dragonfly nymphs are very sensitive to water pollution, thus helping humans to mark which water is still clean and which water is dirty or littered. When becoming an adult dragonfly there are several types that can only be live in forests or natural waters and the presence of these dragonflies can be a sign that the water source is clean and sterile, free of poisons or waste that is fit for consumption by other living creatures.
