Cicada or pupa, first become butterfly cicada, cicada, not butterfly; Pupa is a caterpillar turning into a butterfly; Cicada can only live for ten days, and it takes several years for pupae to become cicadas.
When do caterpillars pupate? How long does it take to become a butterfly? Butterflies and moths go through four stages in their life: first, they are eggs, then they hatch into larvae (caterpillars), and when they grow up, they become pupae. Finally, the adult butterfly flies out of the pupa.
egg
Butterfly egg is the first stage of butterfly development, also called embryonic stage. The structure of an egg is equivalent to a large cell, which contains protoplasm and nucleus, and also contains a lot of yolk. * * * After entering the egg, it combines with the egg nucleus to develop into an embryo, and yolk is a nutrient for embryo development. There is a small hole in the center of the eggshell called the egg hole, which is the passage for * * * to enter the egg, also called the sperm hole. Some kinds of egg holes do not directly penetrate the egg cavity, but a number of hollow egg hole side branches are planted on the inner wall of the eggshell, one end of which is connected with the bottom of the egg hole, and the other end of which is opened in the egg cavity, which are radially arranged around the egg hole and become channels for * * * to enter the egg cavity.
Some butterflies throw their eggs on the grass when they fly and stick there when they land. These larvae all like to eat grass!
Some eggshells are smooth and pearly, some are rough, engraved with many patterns, and some are covered with scales, which are often different due to different insect species. Eggs have different shapes, such as round, steamed bread, oblate, pear and spindle. Eggs are single, sliced, piled and piled in strings. As for the color of eggs, there are many colors such as orange, yellow, green, white, etc., and they present specific patterns of different development stages and types, which are gorgeous and beautiful. Generally speaking, oval eggs have ever-changing colors, which can be used as an auxiliary feature to identify insect species.
This African moth lays eggs on twigs and disguises them to prevent them from being eaten by other insects or spiders.
Some butterflies and moths lay more than 1000 eggs. But this red Hua Die only lays eggs on leaves, and there are seven ridges around the eggs, so it can be recognized.
larva
The eggs hatch into larvae in about a week. The life of newborn larvae is a dangerous beginning. In a few minutes, it will come out of the egg and quickly hide. Once it was safely hidden, it began to eat nonstop. Larvae can get 100 times the income in a few weeks. With luck, it will live for about a month and become a butterfly.
Larval stage, also known as growth stage, is the second development stage in the life history of butterflies.
The larvae of butterflies are called clam larvae. They have a cylindrical body and paired appendages. The body consists of a series of links, which are called somites. The larvae have feeding organs and sensory organs on their heads.
The shape of the head is varied, with little difference between species in the same genus and great difference between different families and genera, which is helpful to identify insect species.
The larva has three pairs of pectoral feet, four pairs of ventral feet and 1 pair of caudal feet, which are attached to the anterior, middle and posterior thoracic segments and five abdominal segments of 3, 4, 5, 6 and 10 in turn. The pectoral foot is a permanent moving organ of the insect body, with a clear section, and the adult foot is developed from the larval pectoral foot.
Gastropoda, also known as pseudopoda, is much thicker than pectoral foot, and consists of unsegmented membranes with rows of hooks at the end. The arrangement of gastropods varies with insect species and their habitats. Gastropoda is the main organ in larval stage, but it is a temporary organ. Once gastropods develop into adults, they will disappear by themselves.
Larval epidermis is rich in chitin, so it can't expand its tool kit indefinitely with the growth of insects, especially the head shell is extremely hard, so when it grows to a certain period, it is necessary to shed the old epidermis and form a wide new epidermis. Among them, the most striking thing is that the head of the newly molted new worm is much larger than the body, which fully shows that the head shell is not good at expansion. When molting, not only the epidermis of the body wall and appendages should be removed, but also the parts connected with the epidermis, such as trachea, foregut and hindgut, which are invaginated by the body wall, especially the parts with chitin. Larvae can't eat or move before molting, which is called "sleep". The newly hatched larvae are one year old, and each molting will increase after one year. Usually molt 4 to 5 times. The molting times vary with insect species, ranging from 3 times to 10 times.
Some larvae have smooth body surfaces, while others have spines, soft hairs, bristles or flesh spines.
The bristles on the first instar larvae of butterflies are called primary bristles. Its number, color, shape and location often vary with insect species, which is an important feature of larval taxonomy.
The prickly hair of zebra butterfly larvae!
This larva will spray acid on the enemy, be careful!
This larva bulges its body to reveal its false eye: "I am a small snake!" " "
How terrible the larvae of lobster moths are!
When disturbed, these larvae will bounce back into the air. Can they scare away birds and lizards?
pupa
After this stage, the larvae will become adults. When the larvae grow up, they need to change their skins four to five times, and each time they change their skins, they grow up once. When it is full, it will change its skin for the last time and then become a pupa.
Pupa is the third development stage in the life history of butterflies, also known as metamorphosis.
Butterfly pupae are collectively called quilt pupae, and their appendages and body parts have been glued into a whole, but the boundary between appendages and head, chest and abdomen remains on the surface of pupae.
When the butterfly larvae grow to estrus, they stop feeding and choose a suitable place to prepare for pupation. The pupation methods of butterflies often vary from species to species. When some species of larvae mature, they descend to the grass surface near the host plant, forming a very thin soil chamber where they pupate. Like a double-ring butterfly. Some spin silk, decorate leaves into nests, and hide in the nests to feed and pupate, such as making butterflies out of rice. Others, like moths, spin silk into thin cocoons and pupate, such as yellow butterflies. The most common pupae are exposed. After the mature larvae choose the pupation site (such as the stem and leaf of the host plant or the surface of other objects), they first spin the silk into a mat, hook it with the tail and foot hook to avoid falling off, then restrain the head from bending back, spin silk repeatedly, and stick a thick thread around the middle waist, then the pupation will not fall off, so it is called pupation. There is also a kind of pupa called hanging pupa, that is, mature larva. After spinning into a mat, hook it with the tail foot, hang upside down, enter the "pre-pupation" stage, and pupate when it matures.
When pupating, after the larval epidermis splits at the midline of the chest and back, the cortex moves backward rapidly due to the continuous expansion and contraction of the pupa body, and extends outward immediately when it retreats to the tail end (at this time, only the cortex near * * * has not been detached), and at the same time, it quickly twists its body and hooks the hip spine on the silk pad, so that it can be safely hung. Then the old skin of the larva falls off, and the body wall of the pupa gradually shrinks and hardens, transforming into various inherent forms.
imago
Adult is the last stage of butterfly development, called sexual stage, which has two forms: male and female. Adults must leave the pupa shell and go out after they mature in the pupa shell. The phenomenon that adults shed their pupal shells is called eclosion. This is not to be confused with the hatching of larvae from eggshells.
At the initial stage of adult emergence, the pupa shell ruptures at the same time in three places: between the antenna wings, the dorsal midline of the anterior, middle and posterior thoracic segments, and the connecting line between the head and the chest. Appendices of the head (antenna and beak tube, etc.). ) and the front legs are extended first, and the middle, back and wings are pulled out immediately. After the feet are attached to other things, the body immediately leaves the pupa shell and hangs upside down for a while, and the soft and withered fins are within 5-6 minutes.
After the butterfly comes out of the pupa, the male butterfly flies around. Busy looking for female butterflies to mate; Female butterflies are busy looking for feed plants for larvae to lay eggs and reproduce.
How to feed cicada pupa after it becomes a butterfly? What does a silkworm chrysalis become after it becomes a butterfly? Then it lays eggs and gets old after laying eggs. Life is coming to an end
Then the eggs hatch into young silkworms and continue to be raised.
Is the word "cicada" spelled wrong? Cicadas do not pupate. After the baby cicada sheds its skin, we call it cicada here.
The premise of how to become a butterfly is that caterpillars emerge into butterflies. ...
How to distinguish between male and female silkworm eggs, larvae (silkworm babies), pupae and moths can be used to identify males and females.
1. The most reliable feature for distinguishing female silkworm from male silkworm is the eighth and ninth abdominal nodes: there are four transparent points on the ventral surface of the eighth and ninth abdominal nodes of female silkworm; There is a transparent point in the center of the ventral surface of the ninth section of the male silkworm.
2. The identification of male and female pupae is also based on the structure of the eighth and ninth abdominal segments. There is a straight line in the center of the ventral surface of the eighth and ninth sections of the female pupa, which separates the eighth and ninth sections; The male pupa has a pair of small protrusions in the center of the ninth ventral surface of the abdomen. There is also an X-shaped symbol.
3, the difference between male and female moths, in addition to identifying the characteristics of tentacles, abdominal size, etc., the most reliable thing is to identify the external genitals of male and female moths. For example, there is a black bone plate near the mating hole of the female moth, and the male moth has a pair of claws.
The development process of silkworm goes through four stages: fertilized egg, larva, pupa and adult, and there are obvious differences in morphological structure and living habits between larva and adult. This development process is called complete transformation.
Silkworm moths are shaped like butterflies, covered with white scales, but have lost the ability to fly because of their small wings. The head of silkworm moth is spherical, with compound eyes and tentacles protruding; The chest has a pair of chest feet and two pairs of wings; There is no abdominal foot in the abdomen, and the terminal body segment has evolved into an external genitalia. Female moths are large and slow to crawl; Male moths are small, crawling fast, and their wings vibrate fast, looking for a mate. Generally, after mating for 3 to 4 hours, the female moth can give birth to fertilized eggs. Silkworm moths (adults) leave their offspring and will soon die. The eggs laid by silkworm moths → hatching silkworms → pupation → moths, and the new generation of circles is completed. This is the life history of silkworms.

How do you know that the cocoon has become a pupa, not a moth? The cocoon will be ready in a week! It has become a pupa, and will not become a moth. I don't know if there are any delicious seeds in my stomach. But I want to ask what kind of silkworm you have, and is the cocoon big? If it is a cocoon, the pupa inside is very small and there is nothing to eat. It is better to go to the market to buy big silkworm chrysalis that you can eat directly! Your little guy is gone as soon as he blows up!
Seven-character Poetry of Breaking Pupa into Butterfly (Song Dynasty) Zhang Xiaoxiang
God paid me for it,
June is choppy.
Beyond cicada dust,
Butterfly dream of water and clouds.
Four Poems by Li Shangyin
one
The lonely butterfly lingers,
Spread your wings.
It should be bright and clean,
Close to the snow frequently.
core
I lost my shadow.
The sun lives deep in the clouds.
Refuse to come out
An idea suddenly occurred to me.
The flowers have fallen early.
The whole summer
Those unborn fruits
Still looking forward to it.
The day when we met in autumn.
The reef stands on the river bank.
Shake the dust off the skirt.
The tide also disappeared.
A few too late to thank the splash.
Don't be breathless.
Some poems that were not planted in time.
Rot into mud
The sound of falling flowers
one
A flower bud that missed flowering.
Borrow the petals of the east wind
There is also a petal lying in summer.
Sweating arm
Wanderers are dreaming of spring.
Return date
Forgot again
Always together. Back off.
Like a primitive warm fire.
Breathless, almost exhausted.
There are boiling rocks in this stream.
Give a warm kiss.
Thin body
Listen to the sound of the planetesimals burning.
In the sky
Like countless fireworks
Blink in your ears
What needs to be done now is
Waiting for a flower to slowly turn into a sweet fruit.
two
Cross your hands and pray.
Put away a lifestyle posture.
From this moment on.
As soon as Buddhism opens, the autumn outside is as deep as the sea.
three
For another kind of piety
I have been fighting Feng Chun for three months.
Set the date for autumn.
Set in the season when melons and fruits are fragrant.
I have to grow up in order to date.
The price of maturity
Is to use a painted face.
In exchange for a ticket to open your heart.
Dating autumn, giving up
All the superficial glitz
Come on, dance.
Rich spiritual contract
Taste is the only guest at the party.
four
My body, from lightness to heaviness
Just like the melting of ice and snow, it nourishes prosperity.
In a hurry between seasons.
No time to sigh.
Calyx reached out and rang the doorbell.
The sound of falling flowers unscrewed a door.
I came from the door.
come in through the door
five
Asphyxiating flower
Sit cross-legged on the calyx
Life returns to zero with a smile.
The fruit is still on the way.
Know nothing.

Is this an apple flower?
It was also for an autumn date. Dai Yue wore stars.
People found one in its lying body.
The largest star

Miss Chun's skirt is shortened by loops.
Show your tall legs and run.
Petals fall backwards.
Only the stamens are erect.
Put your hand into Qiu's pocket.
Want to know?
Grabbed a handful of autumn cool.
And some, uh, fruit being made.
Fragrant and sweet
eight
The wind passed through the branches.
Those tides, twists and turns
Back to the moon.
The moon sets.
Last irrigation
Soilless sky
Sorry ... ... I only have poems. I wonder if you would like to. ...
The sound of falling flowers woke me up.
Ripe red fruit
From the calyx-like clouds, drill out
How to store silkworm cocoons to prevent pupae from becoming moths? what do you want to do? I especially liked to raise this thing when I was a child. I want to expose it to high temperature, low temperature or sunlight. Moths don't eat.
