What kind of insect is this, is it a dragonfly that hasn t grown?

The body length is 12-14 mm, the forewings are 20-23 mm long, and the hindwings are 20-21 mm long.

head orange-yellow, spotless; The antennae are 2 3 long forewings, the 1st and 2nd segments are orange-yellow, and the rest is black-brown. There is one longitudinal markings on each side of the dorsal plate of the anterior thorax, and one dark spot on each side of the shield of the middle and posterior thoracic plates. The wings are transparent, the wing nevus is narrow and long, except for the longitudinal veins are mostly yellow-green, the transverse veins are black, and the half of the PSC base and part of 1A and 2A are yellowish-brown; The inner chamber is quadrangular, some individuals are triangular, and there are two groups of order veins.

The color of the hindwing veins is basically the same as that of the forewing. Feet yellowish-brown, tarsal brown. The abdomen is black-brown, and the 7th dorsal plate is longer than the 8th dorsal plate.

The base margin of the female subreproductive plate is straight, and the apex is broadly indented; The seminal vesicle sac is flattened and narrow, with a small membranous process and a semicircular shape (Fig. 238).

It's so small, it's like it's called damselfly, and it's a small insect that resembles a dragonfly. It's too vague to judge.

No. It's a worm that grows in cotton.

It's a lacewing, and your question is really full of childlike fun.

I can't see clearly, it looks like a damselfly, a dragonfly larva in the water.

Green lacewing... There was a strange smell.

It is a type of dragonfly.

The larvae of dragonflies are water bugs. The color of the water fly varies depending on the habitat in which it lives. The water fly that likes to inhabit the yellow soil is yellow, and the surrounding environment is black, such as the blue dragonfly and the feast fly, depending on the surrounding environment and aquatic plants.

Dragonfly larvae make us feel that its belly is much larger than its head, and it feels fat, and it is very long, at this time the chest is relatively thin, and with each molt, the chest gradually becomes larger, and the abdomen is relatively thinner than before.

Characteristics of life. The larvae, also known as larvae, are generally dark brown or dark green in color, similar in appearance to their adults, wingless, and sexually mature. Lurking in the muddy bottom of the stream or under the stumps and leaves, carnivorous, ferocious, like to catch the slag and eat small aquatic insects and their larvae, large water flies, and can even prey on small fish and tadpoles.

Depending on the species, the duration of the water bug varies from 2-3 months to 1-3 years for the common species, and 7-8 years for the longest to fully mature, during which it takes about 8-14 peels before crawling out of the water and becoming an adult. They usually lurk in the muddy bottom of streams and reservoirs or under the dead branches and leaves, while others like to quietly perch and ambush in dense places with aquatic weeds, waiting for the arrival of prey, such as feasting flies.

1.Overview.

Dragonfly larvae are larvae of insects in the family Dragonfly, also known as dragonflies or dragonflies. Dragonfly larvae have a completely different lifestyle and appearance than adults, so it's easy to misunderstand. Dragonfly larvae are aquatic insects that prey on small benthic animals such as earthworms, water flies, and small fish.

2.Exterior features.

Dragonfly larvae have a completely different appearance from adults, they look like a small slender snake. Their bodies are flat and gray, resembling the shape of a whitebait. The larvae have six legs, and each leg also has many small spines at the base that help them move through the water.

They also have long jaws that stretch freely and are used to grasp their prey.

3.Life course.

Dragonfly larvae and adults have very different lifespans and lifestyles. Dragonfly larvae generally live in water and are considered to be one of the most ferocious predators of aquatic insects. They search for air through the gills on the middle ridge through the oxygen in the breathing water.

The lifespan of dragonfly larvae varies depending on the species, but is generally about three months to one year. The larvae will undergo multiple molts and eventually become dragonfly adults.

4.Difference from adults.

There is a significant difference in appearance between dragonfly larvae and adults. The body of the adult insect is long and thin, the wings show a transparent and emerald green color, the body length is generally about 3-4 cm, and the two long compound eyes can have a 360-degree field of view without dead ends. Adult dragonflies have a short lifespan, generally only a few weeks to a few months.

Adults are usually active in the air and fly in search of food and reproduction.

5.Habitat.

Dragonfly larvae live in water, usually in clear, unpolluted and slow-moving waters, such as rivers, lakes and ponds. They prefer to hide themselves in the silt or plants at the bottom of the water in order to attack when their prey appears. Adults find food and reproduce in places such as woods, meadows and gardens.

6.Function.

Dragonfly larvae are apex predators among aquatic insects, and they can help control the population of certain aquatic organisms and maintain the ecological balance of the water body. Adult dragonflies, on the other hand, are important pollinators for flowers and other plants, promoting the growth and reproduction of plants.

7.Protective significance.

As a part of the ecosystem, dragonflies have important ecological and conservation significance. In recent years, factors such as the decline of biodiversity and environmental pollution have threatened the survival of dragonflies, and it is necessary to strengthen the protection of dragonfly ecosystems and maintain the healthy development of their populations. In addition, protecting dragonflies also helps to protect the living environment and ecological security of humans.

8.Summary.

Dragonfly larvae are special aquatic insects that look like a small, slender snake. Unlike adults, they differ greatly in appearance and lifestyle. Both dragonfly larvae and adults have important functions and conservation significance in the ecosystem, and their protection needs to be strengthened.

Dragonfly larvae are generally dark brown or dark green in color, similar in appearance to adults, wingless, and sexually immature. The color varies depending on the habitat. It usually lurks in the muddy bottom of streams and reservoirs or under the dead branches and leaves, and some like to perch and lie in ambushes in dense places with aquatic plants, waiting for the arrival of prey, such as feasting flies.

The larvae of dragonflies are called water flies (chài). The body color of the water fly is generally dark brown or dark green (black, etc.), and its appearance is similar to that of its adult, without wings, and without sexual maturity. Lurking in the muddy bottom of streams or under the stumps and leaves, it is carnivorous and ferocious, and likes to prey on small aquatic insects and their larvae, large water bugs, and can even prey on small fish and tadpoles.
