The difference between the belly and tail of a dragonfly, the physical characteristics of a dragonfl

Dragonflies have the following differences between their belly and tail:

The abdomen of a dragonfly is often described as elongated and relatively soft, and its interior contains many important organs such as the heart, liver, intestines, etc. In addition, the end of the dragonfly's abdomen usually forms a distinct tail that looks like what we often call a "tail".

However, strictly speaking, dragonflies do not have a real tail, what we usually call a "tail" is actually the end of the dragonfly's abdomen, and the main role of this "tail" is to help the dragonfly maintain balance in flight.

The appearance characteristics of the dragonfly are as follows:

Adult dragonflies have round heads and large compound eyes. It has a box-shaped chest and two pairs of long wings, which can be flapped alternately and can also fly in the air at fixed points. When resting, the wings are flat and vertically combined.

The abdomen is elongated. Dragonflies feed on a carnivorous diet and mainly hunt mosquitoes, flies, butterflies, and even other species of dragonflies in the air.

When hunting, they use 6 legs to catch their prey, and the large amount of coarse hairs on their feet can grasp the prey and prevent it from escaping. The large jaw is quite well developed and can bite the prey and facilitate eating.

They are more able to eat food equal to their body weight in less than 30 minutes. Dragonfly's feet are useful for hunting, but they are not suitable for walking, so dragonflies rarely use their feet except when they stop at branches.

Key Value:

Bionic camera, is to imitate the dragonfly's compound eye unique construction principle made of compound eye camera, can shoot thousands of repeated ** aircraft at a time, dragonfly can hover under a small thrust, forward and backward and left and right sides of the flight, the vibration of its wings can produce vortices and lift the body, the study of the dragonfly's flight mechanism is of great significance to the design and manufacture of the aircraft.

The leading edge of the dragonfly's wings has a thickened keratin mole that can eliminate the tremor of the wings when flying, and the aircraft designers added a counterweight on each wing of the aircraft to prevent the aircraft from breaking the wings due to violent vibrations.

As a common insect, dragonflies are often used as indicator organisms for water weight metal pollution because their larvae are aquatic and have enrichment in mercury and cadmium, and the content of heavy metals in their bodies increases with the increase of water weight metal content.

Question 1: Will dragonflies eat their own tails No.

Male dragonflies should first move ** from the genital orifice to the phallic sac before mating. It may seem like eating your own tail, but it's actually preparing for mating. After mating, it is the dragonfly that lays eggs.

Question 2: Why do dragonflies eat their own tails, and the simple answer What do dragonflies do when they eat their tails Dragonflies don't eat their own tails. The dragonfly eats its tail as a male insect due to its mating apparatus in the abdomen.

On the second and third segments, the genital orifice is in the ninth abdominal segment, so before copulating the tail, it is necessary to move ** from the genital orifice of the ninth segment to the penile sac of the second segment, so the phenomenon of biting the tail appears.

Question 3: Why do dragonflies eat their own tails Before male dragonflies mate their tails, they must first move ** from the genital orifice to the phallic sac. It may seem like eating your own tail, but it's actually preparing for mating.

Question 4: Is Tao Xingzhi right: "Dragonflies eat their own tails when they are extremely hungry?"

1. Phenomenon The phenomenon of dragonflies biting their tails is very common, and people often see dragonflies biting their tails.

2. The reason is that the dragonfly male insect is born in the abdomen due to its copulous organs.

On the second and third segments, but the genital orifice is in the ninth abdominal segment, so before the copulation, it is necessary to move ** from the genital orifice of the ninth segment to the penile sac of the second segment, so there is a tail bite.

Question 5: Is it true that dragonflies eat off their tails when they are extremely hungry? It's true. Although the dragonfly has a very short lifespan, it really eats a section when it is very hungry, and it will not die because it will grow new ones.

Question 6: Does a dragonfly eat its own tail when it is hungry, and if you know why it eats it When a dragonfly is extremely hungry and has nothing to eat, it will eat its own tail, and it will take about two weeks for it to grow a new tail. If you search on the Internet, you may not find this answer, but this is the correct solution, please believe!

Question 7: Why do dragonflies "eat" their tails? Everyone thinks that dragonflies will eat their own tails, in fact, it is not right, dragonflies have a slender body, bright colors, elegant posture, flexible and agile flight, interesting and attractive, it is a favorite ornamental insect of people, often active in the field, garden and other places during the day.

Most dragonflies are 30 to 90 mm long, with a few species reaching up to 150 mm, while others are very slender and less than 20 mm long. The idiom dragonfly dotted with water quoted by people actually refers to the phenomenon of female insects laying eggs after mating, and every time they point on the surface of the water, they lay 1 egg, and the action is very fast. People use this idiom as a metaphor for the meaning of not going deep.

The needle on the dragonfly's tail is a long needle.

Dragonflies are generally larger, with long and narrow wings, 3 single eyes, 1 pair of antennae, thin and short, chewing mouthparts, elongated, flat or cylindrical abdomen, anal appendages at the end, thin and weak feet, and hooked spines. The larvae (larvae) develop in the water, breathe with the rectal tracheal gills in the water, generally go through more than 11 molts, and it takes 2 or more years to crawl out of the water along the aquatic weeds, and then finally molt and feather into adults.
