The dragonfly is an ancient insect that has survived for more than 300 million years.

Dragonflies are an order in the Insecta family, which includes insects such as dragonflies and mantis cicadas. Dragonflies usually live around water, lakes, swamps, and other waters, and some live in mountainous areas and woodlands.

Because of its unique flight style and beautiful appearance, it is highly appreciated around the world.

The dragonfly has a long and thin body with two pairs of wings, the front, and hind wings are similar in size and shape, allowing the dragonfly to flap rapidly and make the dragonfly fly through the air.

The wings of dragonflies are usually transparent or metallic, and some species have colourful patterns and patterns.

The dragonfly's head has two large eyes that provide a 360-degree view of the world, which is helpful for feeding and escaping natural predators.

The front thorax and abdomen have many bones and muscles that allow dragonflies to achieve a variety of flexible movements in flight, such as flying forward, backwards, ascending, descending, and hovering.

Dragonflies are predatory insects, feeding mainly on insects, especially small insects such as mosquitoes and flies.

Dragonflies have a unique way of feeding, they will hover in the air, wait for the prey to approach, and then quickly strike and swallow the target with a powerful mouthpiece. Dragonflies are also one of the natural enemy insects that play an essential role in the population control of other insects.

The life cycle of dragonflies is generally about six months to a year, with most of that time spent in the larval form in the water.

Dragonfly larvae are called dragonflies or water lacewings, and they have long bodies and three pairs of legs that allow them to swim freely in the water. Dragonflies grow up by moulting and eventually crawl to land and moult into adults. During the metamorphosis process, the dragonfly's wings gradually unfold, dry and begin to fly.

Another unique feature of dragonflies is that they can change the angle and vibration frequency of their wings in flight, allowing for changes in flight speed and direction, thus allowing for various flexible flight manoeuvres.

Dragonflies also have an important role in the ecosystem. They are predatory insects in water and on land, controlling large populations of pests and protecting vegetation and crops. Dragonfly larvae also serve as food for aquatic organisms and contribute to the balance and stability of marine ecosystems.

Dragonflies also have a place in human culture and are regarded as a symbol of good luck. In countries such as Japan, there is also traditional handicraft with dragonflies as the theme, such as dragonfly hangings and dragonfly hair cards. Overall, the dragonfly is an important insect with a particular life form, agile flight, and control over several pests.
