Seeking to know a kind of moth, is this a moth?

Why do moths fight fires?

There are generally two explanations, but they both basically mean the same.

1. After long-term observation and experiments, scientists have finally uncovered the mystery of "fighting fires". They found that insects such as moths relied on moonlight to orient themselves when flying at night. The moth always makes the moonlight cast into its eyes from one direction.

After the moth is running away from a bat or turning around an obstacle, it only needs to make another turn, and the moonlight will still come from the original direction, and it will find its direction. This is a kind of "astronomical navigation".

The moth sees the light and mistakenly thinks it is "moonlight". Therefore, it also uses this fake "moonlight" to discern the direction. The moon is so far away from the earth that moths can fly in a certain direction as long as they maintain a fixed angle to the moon.

However, the light was so close to the moth that the moth, instinctively keeping itself at a fixed angle to the light source, had to circle the light until it finally died of exhaustion.

2. Many insects only fly among the flowers after the sun sets and nightfall, collecting nectar on the one hand and pollinating plants on the other. In the dark night, they can successfully find the flowers, which is the credit of the "flash language". When nocturnal insects fly in the air, due to the vibration of their wings, they constantly rub against the air, produce heat energy, and emit ultraviolet light to "ask for directions" to the flowers. When the special structure of the insect receives the echo of the "luminous light" of the flower, it will fly away to pollinate the flower, so that it can bear fruit and pass on to the offspring.

In this way, the light language of insects also contributes to the prosperity of nature. Therefore, nocturnal insects are mostly phototaxis, and "moths fighting fires" is a true portrayal of this habit. In addition, in fact, the moth does not subjectively want to die in the flames, but because of the structure of its compound eyes, it gradually approaches the fire when it flies around the fire at a spiral angle, causing the fire to be extinguished.

Moths fight fires, in fact, moths just keep their flight direction at a certain angle with the light source, as it continues to fly, it has to constantly change the angle, and the trajectory is gradually closer to the light source, just like the shape of the mosquito coil, flying around the light source, and the radius gradually shrinks, and finally touches the light source, if unfortunately it is flying around the flame, then ......It didn't go straight to the light source.

Not only is I a water beast understood, but the moth's body has no heat, and light has heat, and it flies around the light to absorb heat to maintain body temperature. So under the street lamp at night, you can see a lot of insects.

Don't eat.

Adult (silkworm moth) pupae turn into moths after 13 to 14 days and emerge from cocoons. When the silkworm moth emerges from the cocoon, it spits out an alkaline liquid that dissolves the sericin that adheres to the silk, causing the silk to separate. Then use your head and feet to pull away this part of the filament to form a large hole that is drilled out of the hole.

After the silkworm moth emerges from the cocoon, it is followed by male and female copulation. Female moths are relatively hypertrophied, inflexible in movement, and have hairy strands at the end of their abdomen. Male moths are thin and flexible, and have no hairs at the end of their abdomen.

Male moths and female moths die after mating and laying eggs, which is mainly due to the degradation of the mouthparts of silkworm moths and the inability to eat any food, and the nutrients and energy they need to live depend on the accumulation of larval periods, and almost all the nutrients stored in the body are exhausted when mating and laying eggs; In addition, the aging and decay of the internal tissues of the silkworm moth is also the cause of its death.

Relying on the energy accumulation of larvae, they die after mating and laying eggs.

Judging from your **, this is a grain borer.

Judging from your wide yard **, this is a grain borer. There is this general spine at home, which is the food worm at home.

The characteristics of the grain borer are:

Small moths. The body length is 5 9 mm, the wingspan is 13 16 mm. The head is grayish-brown, and the abdomen is grayish-white. There is a tuft of black-brown scales stretching forward and downward between the compound eyes on the top of the head.

The lower lip should be well developed and extended to the front. The forewings are elongated, the basal half is yellowish-white, and the rest is bright russet, with scattered black markings. Hindwings grayish-white. Generally, the male adult is smaller, the abdomen is thinner, and the end of the abdomen is bifid, and the female adult is larger, the abdomen is rougher, and the end of the abdomen is round.

You can't see clearly, you can see that the unfrost moth (scientific name: psilogramma menephron), also known as paulownia gray moth, sycamore moth, gray-winged moth, is an insect of the genus Frost Moth in the family Lepidoptera. It is distributed in North China, South China, East China, Central China and Southwest China.

It mainly harms ash, gold-leaf privet and paulownia, but also harms lilac, plane tree, willow, sycamore and other garden plants. The larvae feed on the epidermis of plant leaves, causing the affected leaves to appear notched, holes, and even eat up the whole leaves.

Scorched blue moth is a species of the genus Glancia moth in the family Inchmoth.

The mango moth, the Latin name changed to amplypterus panopus, belongs to the lepidopteran moth Zen Feng Hui family.

Judging from your **, this one is a type of noctuidae.

Noctuidae refers to a group of insects in the family Noctuidae. The body is triangular, stout, with a wingspan of 8 305 mm (1 3 12 in), generally dark grayish-brown, but some tropical species are bright and shiny, densely scaly. Evening and night flights.

Phototaxis.
