Spring has arrived and everything has awakened. After two years of raising silkworm babies, watching the silkworm babies grow up slowly, bit by bit, the silkworm babies are our "pets" and our "children" in my eyes. Although he is not pretty, and even some people think it is a little scary, our feelings for silkworm babies are very deep and deep
Before the silkworm baby came out of the shell, the shell was black.
As the temperature rises, the silkworm baby comes out of its shell.
When the little silkworm baby bites the shell and comes out from the inside, you can compare the above photo to see, and you will find that the black silkworm shell just now is already white.
Mulberry leaf
Pick the best and youngest mulberry leaves from the mulberry trees.
Newborn silkworm babies should be placed on the freshly picked mulberry leaves, and there should be no water on the mulberry leaves. Otherwise, it is easy for silkworm babies to diarrhea and sacrifice their lives. Black little! One leaf is enough for many silkworm babies. Newborn silkworm babies can only eat freshly produced young leaves, not older leaves
The body of the silkworm baby is divided into three parts: head, chest and abdomen. The head is small, and you can only see a large mouth, and the other parts are piled together, and you can't tell what is what. There are three pairs of feet, the pointed and the back of the abdomen are not the same, the silkworm's gastropods have a small hook, when you hold the silkworm in your hand, its gastropods will be firmly hooked in your hands, like a small suction cup, it is difficult to take down, and there is a pair of tail feet on its tail. On the front few parts of the abdomen, there is a black "disc" on each side of the body, which is its nose - stomata, they all breathe by these small holes, and when they breathe, they have a thick and thin line on their backs, which is the "dorsal vasculature", which is where the silkworm baby "transports blood". This dorsal vasculature is that the larger the silkworm, the clearer it can be seen, the fourth-year-old silkworm can see it, and if it is two or three years old, it will not be clear
The silkworm baby slowly grew up, looking fat, looking at the middle of the picture above, this silkworm is molting, and half of the skin has already been molted. Silkworm babies desperately eat mulberry leaves, and they are getting fatter, but sometimes they will suddenly stop moving, looking like they are going to die, oh, that is the silkworm babies are sleeping, then do not touch them, after a day or two they will molt. Silkworm baby's life is divided into eggs, larvae, pupae, moth four stages, just out of the shell of the silkworm called a first-aged silkworm, because it is black and small, so also called ant silkworm, in the larval period will molt four times the skin, in this period of time, the silkworm baby every time the skin is older, the body will grow a little, and it is longer and larger, the longer and thicker, the longer and whiter. After molting the skin four times, it becomes a five-year-old silkworm, and the silkworm baby will spit out a cocoon after eating mulberry leaves for a few days.
Looking closely at the picture, the silkworm baby in the middle has shed its skin and is already half off.
This is the silkworm baby who is about to spit silk, at this time the color of the silkworm baby has some small changes, it looks slightly yellower, and the yellow transparency, especially the chest, seems to be able to see the silk inside its body.
I saw that they first spit out a piece of snow-white silk with their mouths to weave a "z" shape, and then used the silk to surround themselves in a circle and turn it into a transparent ball.
Looking into the cocoon, the head of the silkworm baby swayed and swung, the silkworm hung in the yellow silk thread, the head was still spinning and spitting silk, seeing here, touched and sad by them. Touched by "spring silkworms to the end of the dead silk", sad "as a silkworm self-binding".
But the strange thing is: some silkworms spit out white silk, others spit out "gold" silk--- yellow, why do silkworm cocoons have golden yellow?
After cutting open the cocoon, we can see the silkworm pupa lying quietly inside, enjoying the warmth brought to them by the home they have built. There is also a pile of shrunken skin inside, and if you look closely, you can see the feet and tentacles of moths looming in the pupae.
Silkworm pupae are also male and female, but I haven't yet learned how to distinguish them
After another two weeks or so in my anxious waiting, it was a happy morning, and I saw the silkworm moth come out, the pale yellow body, a pair of feather-like antennae, and a large abdomen, was it a little different from what everyone imagined? ~！
Male or female, I still don't know, huh.
Silkworm moths have begun to mate Oh, children are not suitable! After the cocoon, the female moth emits a smell at the tail to lure the male to cross the tail, and the male dies after the tail. Alas, the child who is suffering from death does not know what his father looks like! ~~
After a few days, the female moth lays about 500 eggs in a night, and then slowly dies. "Spring silkworms to the end of the dead silk", they spit silk cocoons, raise offspring, but also about to end their own lives, but it does not matter, their little babies will make more contributions to humanity than their parents. I look forward to next spring...
