When I was a child, I loved to play in the fields, and I would see a lot of flying dragonflies, and when we were young, we thought it was very beautiful and wanted to catch them. Adults always tell us not to hurt them, they are not only good helpers for us, but also a beneficial insect.

Dragonflies are invertebrates belonging to the class of insects, and it has been found that they are the insects with the most eyes in the world, and their eyesight is very good, and they are relatively old insect groups. At the same time, dragonflies are also dragonflies and are also divided into three suborders: Differentptera, Homoptera, and Mesoptera, and there are about 5,000 species of dragonflies in the world.

Dragonflies generally fly and stop in ponds or ridges by small rivers, but what you don't expect is that when you are a child, dragonflies live in the water when they are still young babies, just like tadpoles. When they were young, their name was not dragonfly but water fly, they developed in the water and breathed with gills, they barely moved, and often waited for food to be delivered to their door.

When they grow up, they have wings to fly and prey on flying insects, and their food is mainly mosquitoes and some different kinds of harmful insects, but the things they eat are also somewhat different from dragonflies at different times. The early dragonfly larvae feed on small crustaceans and protozoa, and the later larvae feed on midnight mosquito larvae, aquatic beetles, snails, and even small fish.

There is a clear association between the eating habits of dragonfly larvae and their species. Dragonfly larvae feed mainly on Diptera larvae, such as rockfly larvae, midges and some small fish, while species that inhabit still water mainly feed on Diptera larvae such as tadpoles, small shrimp fish, daphnia and midges. They are the natural enemies of pests, while the natural enemies of dragonflies are some birds, relatively large omnivorous fish.

In addition, don't look at the dragonfly so thin and small, its food is very powerful, a kind of green dragonfly commonly known as "green head flute" can easily solve about 2,000 aphids and other small flying insects a day, a horse big head dragonfly can eat nearly 1,000 small flying insects a day, and can also eat 40 flies or 840 mosquitoes in an hour. This has been reflected since childhood, when I was a child, the larvae of dragonflies loved to eat mosquito larvae, and they could eat the larvae of 3,000 mosquitoes a year, which was destined to be the cultivation of foodies.

After reading it, do you know what dragonflies eat? But don't forget to protect them!

Dragonflies also have children, what kind of little dragonfly do you think this is?

Hello dear! Dragonflies also have children, what kind of little dragonfly do you think this is? Answer:

When dragonflies are young, they are called water flies, and when they are young, dragonflies live in the water, breathe with their gills, and when they grow up and grow wings, they can quickly dig and fly in the air. The larval dragonfly can be domesticated, when the dragonfly grows up, it can not be domesticated after flying, otherwise it is easy to cause the dragonfly to die. Dragonfly larvae can be kept in fish tanks.

Water and fine sand are added to the tank, and some aquatic plants are placed on the surface of the water. At the same time, a wooden stick is inserted diagonally in the water to expose a piece on the surface of the water, so that the larvae can have partial feathers after coming out of the water.
