I know what my name was when I was young

When I was young. Under very deep soil. Very few people have seen them. When it grows to a certain size. They all turn into adults in one night!

Cicadas are widely distributed, distributed in the north and south of China, mainly inhabit broad-leaved trees, the life cycle is 3 5 years, the adult life span is 2 3 months, the oviposition period is in the month of each year, the overwintering eggs hatch in May and June of the following year, and the egg period is nearly 300 days.

The activity of the overwintering nymphs was affected by ground temperature and the sap of the host plant, and when the temperature was higher than 10 15, the sap of the tree began to flow rapidly, and the overwintering nymphs began to sting, suck and feed. Nymphs (cicada ants) hatched from overwintering eggs, burrow into the soil and suck the sap at the roots of the host plant. As the age increases, they create earthen chambers of different sizes and shapes to live in.

Part of the wall of the earthen chamber is attached to the roots of the plant so that it can be fed. When the temperature drops in autumn, they burrow into deep soil for wintering, and then migrate upward to the roots of trees after the spring is warm.

The largest number of nymphs in the soil is in May, when the overwintering eggs hatch into the soil in large numbers, and the last instar nymphs are about to emerge and molt into adults. After completing the whole life process of the nymphs in the soil, the mature nymphs emerge from the soil in May and August, and crawl to the branches of shrubs, weeds, stems, etc., and fix themselves on the bark branches and leaves with their claws and the thorns of their forefeet, molting and feathering into adults.

Adults are at their peak in June and late in October. About 20 days after the adult emerges, the tail lays eggs, the adult oviposition period is the peak period of adult oviposition in July and August, the end of oviposition is in October, and the final period of adult eggs is November. Adults mostly emerge at 20:22:00 at night and 4:6 at 6:00 in the morning, and the ratio of females to males is basically 1:

1 ratio. Reference**.

We all said we didn't know.

Is Diao Crystal's number back, and ask him for the school uniform!! Let's have a bar for the sake of having fun! Girls' Front.

Cicadas, Futian, mountains know, autumn cool.

The reason why they are called [知了] may be because they are too loud. It's too much. Just like those who think they are smart, they like to express themselves, they love to talk a lot, they talk loudly. Ask what you know. Know. Former hometown.

The scientific name of the larvae is knownCicada chrysalis, the dialect is also called".Got to know the monkey

Cicada pupae in addition to containing amino acids.

In addition to proteins, they also contain their own secondary metabolites, but these secondary metabolites are harmless to humans. If you want to feed on insects, you should eat the larvae as much as possible, because the larvae do not have a more complex structure and are relatively easy to feed. Many bugs have been eaten for decades, even hundreds of years, and are empirically harmless to humans.

Expansion:

The nymph of the cicada. Spend the first two or three years of its life underground, maybe longer. There is a cicada in the United States that can live for 17 years. Its nymphs have to survive a dark life for years or even decades.

During this time, it sucks the liquid from the roots of the tree. Then one day he broke through the ground and found a tree to climb with his survival instinct. After several years of slow growth, it crawls out of the ground as a reservoir of energy. Its front paws, which are used to burrow, can also be used for climbing.

The cry of the chilling cicada is all, all over", the onomatopoeia gets its name.

Dialects": Crickets (蛥音fold, 蚗 in the column, one sound Jue), Qi is called the stinger (Xi Lu two sounds), Chu is called the cricket (Zhuangzi said: the cricket does not know the spring and autumn also), or the name of the cricket (sound zero). From the east of the Guan, it is called the 虭蟧 (ermine material two sounds), or the 蝭蟧 (蝭, sound cry).

This "from the Guan and the east is called the 虭蟧 (mink material two sounds), or the name of the 蝭蟧 (蝭, sound cry)" should be an early word.

The common name of the cicada is the eldest sister, and the ** of the "sister" is a beetle and a clust, and it is even possible that the ** of the word "big sister" is "a clust".

Judging from the "Dialect" and its notes, in fact, the ancients seemed to be very confused about which cicada corresponded to which name, and Guo Pu's notes thought that this thing was very confusing, such as:

It is called the cold lizard, the cold lizard, and the cold lizard is also (according to Erya, the dragon is the cold lizard, and the moon order is also said: the cold lizard is singing, and the cold lizard is not a fistula. The names of these cicadas are elegant and mixed, and there is no detailed evidence. The chill and the scorpion are also like small cicadas and are blue.
