Dragonflies mainly feed on mosquitoes, flies and various small insects.

Adults prey on flying insects in flight, mainly feeding on mosquitoes and other harmful insects, and dragonflies eat something different in different periods. Early dragonfly larvae feed on aquatic animals such as small crustaceans and protozoa, while later larvae feed on chironomid larvae, water beetle, snails and even small fish. The prey of eclosion adults is usually flying insects, but some often eat their own prey of 6%.

The food intake of dragonflies is also amazing. A big green dragonfly, commonly known as "Qingtouleng", can eat about 2, aphids and other small flying insects in a day. It is said that a horse-headed dragonfly can eat nearly 1 small flying insects in one day and 4 flies or 84 mosquitoes in one hour. At the same time, the larvae of dragonflies especially like to eat mosquito larvae. A dragonfly larva can eat more than 3, mosquito larvae a year.

why do dragonflies water

The female dragonflies are laying eggs. Dragonflies usually lay eggs on aquatic plants in rivers and ponds. The larvae hatched on aquatic plants after the eggs are discharged are called "hydra". Hydra has to crawl in the water for a long time, ranging from one year to seven or eight years before it can emerge into dragonfly adults.

After the emergence into an adult, the short and fat belly becomes more and more slender, and the wings that were folded together are unfolded one by one, and finally it becomes a dragonfly like a small plane. It can be seen that "catching water" is a natural part of dragonfly life-laying eggs to reproduce.
