What kind of food does dragonfly eat?
Dragonflies generally fly in ponds or rivers, larvae (juveniles) develop in the water, adults prey on flying insects, mainly on mosquitoes and other harmful insects, and dragonflies in different periods eat different things. Early dragonfly larvae feed on aquatic animals such as small crustaceans and protozoa, while later juveniles feed on Chironomus larvae, aquatic beetles and snails, and even small fish. the prey of Eclosion adults is usually flying bugs, but some often eat 60% of their own weight.
How much does the dragonfly eat?
The food intake of dragonflies is also very astonishing. A large green dragonfly, commonly known as "Qingtou Leng", can eat about 2, 000 aphids and other small flies in a day. It is said that a horse dragonfly can eat nearly 1000 small flies in a day and 40 flies or 840 mosquitoes in an hour. At the same time, dragonfly larvae also like to eat mosquito larvae. A dragonfly larva can eat more than 3000 mosquito larvae a year.
Why do dragonflies order water?
The female dragonfly is laying eggs. Dragonflies usually lay their eggs on aquatic plants in small rivers and ponds. The larvae hatched on aquatic plants after ovulation are called "water flies". Water flies have to crawl in the water for a long time, at least one year, or seven or eight years before they can become adults of dragonflies. After feathering into an adult, the short and fat belly becomes more and more slender, and the previously folded wings spread out one by one, and finally become a dragonfly like a small airplane. It can be seen that "dragonfly scratching the surface" is a natural part of dragonfly life-laying eggs to reproduce.
