Dragonflies are laying eggs. When the dragonfly mates, it excretes the fertilized egg through the tail, and in order for the egg to sink to the bottom, the tail will stick into the water, and each ovulation is very rapid, so the dragonfly water. Dragonfly water is the eggs of dragonflies, the eggs go directly into the water, or lay on aquatic plants, the eggs will hatch in the water, and when they grow up, they will crawl out of the water and become a dragonfly.
<>Actually, we colloquially call it"Dragonflies"Just a general term, in fact it is a large group, according to biological classification.
Its classification is Dragonflyidae. Dragonflies are a relatively primitive group of winged insects belonging to the order Toxoplasma and mayflies.
Eye. Contains three suborders. Dragonfly water?
Why divide like a sheep eating grass is actually a natural behavior. And what we usually say"water", in fact, dragonflies are laying eggs. Dragonfly launching is when the tip of the dragonfly is close to the surface of the water, laying eggs directly in the water, allowing the eggs to enter the water.
The eggs turn into nymphs in the water.
Called Duobao, Duobao is found around the weeds of streams, lakes and rice paddies and eats small animals in the water such as mayflies, tadpoles and small fish. Do dragonflies reproduce very differently? Surprisingly, an insect that flies in the sky is going to lay its offspring in the water and fly from the water to the sky.
The evolution of this mode of reproduction remains a mystery. Dragonflies not only have special ways of laying eggs, but also have different ways of mating. During mating, the female dragonfly bends forward and connects to the genital hole under the male dragonfly's abdomen to complete fertilization.
Do all dragonflies have water? No, dragonflies do lay eggs near water, but not all dragonflies lay eggs in water. Some dragonflies lay eggs by inserting their bellies into the water.
For example, black slippery. Dragonflies also lay eggs by diving, like the nipples, and also by diving. Other dragonflies, such as sandflies.
Dragonflies, which drop their eggs into the water during mating. Other dragonflies lay their eggs on soft tree trunks or on the ground. Other dragonflies lay their eggs on grass stems, plants in water, and leaves, such as the Japanese dragonfly.

In fact, it's the female dragonfly laying eggs.
This is because dragonfly eggs hatch in water, and larvae also live in water, and when female dragonflies lay eggs on the surface of the water, most of them touch the surface of the water with their tails when they fly and expel their eggs. The eggs go to the water and attach to the aquatic weeds.
-
Yes. It is because dragonflies will breed and lay eggs in shallow places in the water nest, which has a lot to do with the body structure and habits of dragonflies.
-
That's true, because dragonflies need to lay their eggs in the water so that the baby dragonflies can come back to life. Otherwise, the little dragonfly will die.
-
Not all dragonflies have the habit of laying eggs in the water, and this behavior is mainly due to some species of the dragonfly family, such as the yellow dragonfly. Other dragonflies lay their eggs in the water in other ways.
Before laying eggs, the common jade-banded dragonfly will look for suitable floating objects on the water surface, such as tree branches and wood segments, first rest on the floating objects, and then lay their eggs on the surface of the underwater part of the floating objects.
Other methods of spawning
Giant dragonflies take another form of egg-laying, they often weave along the streams under the forest in search of shallow mountain streams, and when they find a suitable spot, the adults hover over the water, bend downward, and repeatedly insert their abdomen into the soil at the bottom of the stream at an angle almost perpendicular to the surface of the water to lay eggs.
The female has a sharp and powerful ovipositor at the end of her abdomen, which can easily insert the end of her abdomen into the surface layer of the soil to lay eggs. Some species of the Fly family lay eggs with the help of aquatic plants, where the adults protrude their abdomen underwater and pierce into the stem of the plant, where they lay their eggs. Some damselflies can even dive, crawling underwater along the aquatic plants and laying their eggs in the stems of the plants.
Waterfall damselflies, which are native to the Americas, are even able to fly into the waterfall and lay their eggs on the stone walls inside the waterfall.

Yes, dragonflies are laying eggs.
Dragonflies are dragonflies laying eggs, which are laid directly in the water or on aquatic plants. The larvae that hatch from their eggs are called water flies. The water fly often sticks out of its lower lip with a hook-like hook to catch small animals in the water.
The water fly is an expert swimmer, it uses a jet type, as long as the abdomen is compressed, the water will be sprayed back, and the body will naturally rush forward, and the speed is extremely fast. Breathe through the gill of the rectum. When the water fly grows up, it climbs a branch or stone protruding from the water, and it grows into an adult dragonfly like a flying dragon in the air.
Dragonfly is a generic name for invertebrates, insects, dragonflies, and suborder Paraptera. The base of the hindwings is slightly larger than the base of the forewings, and the wing veins are slightly different. When resting, the wings lie flat on the sides.
The larvae are short and thick, with rectal gills and no caudal gills. There are 11 departments in total, including 3 general departments, including the general family of dragonflies, the general family of dragonflies, and the general family of dragonflies. Flyflies and dragonflies are the most common and are widely distributed throughout China.

It is false to say that all dragonflies have the habit of laying eggs in a little water.
Not all dragonflies lay eggs in the water, the main ones that lay eggs in the water are some dragonflies of the dragonfly family, and other dragonflies lay their eggs in the water by other means, such as some burrow into the water to lay eggs.
Breeding characteristics of dragonflies.
When dragonflies reach sexual maturity, they will fly to ponds, rivers and other mating places where they can lay eggs, among which male dragonflies will arrive early at the mating sites, occupy a certain position along the river bank or water surface, and defend their territory like birds, expelling other invading males. If a female approaches or flies into the field, the male tries to mate with her. A small number of species have courtship and ostentatious behavior before mating.

In dragonfly mating, the male holds the female's head or chest with a gripper at the end of the abdomen, and lures the female to bend her abdomen forward through its movements, touching the mating apparatus at the base of the male's abdomen. Dragonflies mostly land on the ground when mating, but they can also be carried out in the air, and the mating time is a few seconds to several hours. Females lay eggs immediately after mating, or after hours or days.
Dragonflies lay eggs in two ways. Species with well-developed ovipositors lay their eggs in or on water or plant tissues, and some climb to the surface of the water to lay eggs, which can be immersed in water for more than 1 hour. Adults need a warm climate, food, and water suitable for laying eggs to reproduce.
Fish and birds prey on dragonfly larvae, and the larvae also eat each other. Adults are almost invulnerable after leaving the feathering site, flying quickly and nimblely, avoiding almost all predators.
Dragonflies are laying eggs.
Dragonfly eggs are laid directly into the water, or on aquatic plants. The larvae that hatch from their eggs are called water flies. The water fly often sticks out of its lower lip with a claw hook to catch small animals in the water. >>>More
Dragonfly dotting water – point to point.
Interpretation: The metaphor is superficial and not deep. >>>More
Dragonflies point to water, in fact, dragonflies in the process of water, in the process of laying eggs in the water, that is, this is actually a kind of reproductive behavior. <> >>>More
Abdomen. Why do dragonflies order water? It turns out that although dragonflies are land-living insects that soar in the air all day long, their larvae have to live in water, and in order to reproduce, they must choose to lay eggs in places where there is water. >>>More
Dragonflies often fly low along the surface of the water, and their tails point to the surface of the water from time to time, and people call this picture "dragonfly dotting water". So why do dragonflies order water?
