How silkworms come out of silkworm eggs and what silkworm eggs look like

The eggs are initially very similar to millet, pale yellow or off-white, but later the eggs will sink into a hole and turn brown or black.

Of course, you know that silkworms are going to grow into cocoons, into chrysalis, and then into white worms, ovulate, and then die greatly...

Basically, after a year, the silkworm will crawl out of the egg on its own, and it looks like an ant when it first crawls out. At this time, you should pay attention to collecting, and you can not feed mulberry leaves, you can feed some leftover tea leaves.

By the way, when the silkworm eggs are just expelled from the mother moth, the eggs will stick to the prepared straw paper on their own, and at this time some water should be sprinkled on the eggs. After some time, some water should also be sprinkled. Then you can put it in a place with the right temperature...

The experience of raising silkworms by yourself is for your reference!

The outer layer of the silkworm egg is a hard egg shell, and the inside is the yolk and serous membrane, and the embryo in the fertilized egg continuously ingests nutrients during the development process, and gradually develops into an ant silkworm, which crawls out of the egg shell, and the egg shell becomes white or light yellow after the egg shell is empty. When the silkworm hatches from the silkworm egg, the color of the body is brown or russet, very small, and there are many fine hairs, and the appearance is a bit like an ant, so it is called ant silkworm. The antworm is about 2 mm long and about mm wide, and after crawling out of the egg shell, it will eat mulberry leaves after 2 to 3 hours.

The silkworm eggs are oval-shaped, resembling sesame grains, about 1 mm wide and about mm thick. The eggs are pale yellow when they are first laid, turn red bean color after 1 2 days, and then turn gray-green or purple after 3 or 4 days, and then do not change anymore, which is called fixed color. When the baby silkworm crawls out of the egg shell, the empty egg shell will turn white or yellowish.

What are silkworm eggs like

A female moth can lay about 450 500 eggs at a time, weighing about 1 gram in total.

The silkworm egg has a hard egg shell on the outside, and the yolk and serous membrane on the inside. The fertilized eggs continue to take in nutrients and develop into embryos, and then gradually develop into ant silkworms.

When the ant silkworm develops, it can basically crawl out, and the ant silkworm will be eaten along with the egg shell when it hatches, so the egg surface must be disinfected before the larvae hatch.

The silkworm eggs are oval, slightly flattened, and slightly pointed at one end. It looks like a fine-grained sesame seed with a hail of embers, about 1 mm wide, about 1 mm thick, and weighs about 1 gram.

Silkworm eggs. It is pale yellow or yellow when it is first born, turns red bean color after 1 to 2 days, and turns gray green or purple after 3 to 4 days after Qing Da longitude.

The silkworm eggs look a lot like fine-grained sesame seeds, about 1 millimeter wide and about millimeters thick.

When the silkworm eggs are first laid, they are pale yellow or yellow, and after 1 to 2 days, they turn red bean color, and after 3 to 4 days, they turn gray-green or purple again, and then they do not change again, which is called the fixed color of the fighting hall. The outer layer of the silkworm egg is a hard egg shell, and the inside is the yolk and serous membrane, and the embryo in the fertilized egg continues to take in nutrients during the development process, and gradually develops into an ant silkworm, crawling out of the shell of the buried silver stupid egg, and the egg shell will become white or light yellow after being empty.

Mulberry silkworm eggs are small yellow particles.

Silkworm eggs are the kind of silkworm chrysalis we eat. Its body shape is thick in the middle with two pointed ends, and the middle of the body is moving.

1. This is the silkworm seed that I just received. It's dark and small. It's about the size of a grain of millet.

2. After a few days, some silkworm seeds begin to turn white, and silkworm seeds should be placed in a warm place. If you buy it in the spring, you should keep it warm in a cardboard box. Then a small silkworm came out and couldn't eat many leaves, so it was enough to cut the leaves and feed them a little.

Because you don't eat much, the leaves are easy to dry out, so you should feed them often.

3. More and more silkworms are coming out, and some can be seen to be coming out soon.

4. The silkworm that molted for the first time turned white after eating mulberry leaves. Day by day, it is getting bigger and bigger, and I can eat more and more.

5. The speed of eating mulberry leaves is getting faster and faster, and the leaves are becoming more and more in short supply, and each time the skin is molted, it becomes larger. Keep it cool in your hands, don't let them go hungry, and keep feeding the leaves. Silkworm raising is hard to feed almost every three or four hours.

6. Don't eat mulberry leaves, prepare to form cocoons, and keep looking for a suitable place. The body contracted, getting shorter and shorter, and the middle stomach became fatter and fatter.

7. Finally found a suitable position for the attack, and Tusi wrapped himself in it.

8. Continue to wrap yourself, keep spinning, and keep getting smaller until a perfect cocoon is formed.

The above is the change chart of the growth order of silkworms!

The reproductive development of silkworms will go through four processes, namely silkworm eggs, larvae, pupae and adults, among which the shape of silkworm eggs is smaller, the width is about 1 mm, the larvae will crawl out of the silkworm eggs, mainly feed on mulberry leaves, after molting four times, the larvae will spin silk into a pupa and wait for about 14 days, the adult will drill out of the pupae.

1. Silkworm eggs

Silkworms mainly reproduce with eggs, the shape of the silkworm eggs is small, the width is about 1 mm, the thickness is about millimeters, it looks like fine sesame seeds, and the silkworm eggs are light yellow when they are just laid, after 1-2 days, they will become red, and after waiting for 3-4 days, the silkworm eggs will become gray-green or purple, and then the young silkworms will crawl out of the eggs.

2. Larvae

When the young silkworm crawls out of the silkworm egg, the body is black or brown, the shape is similar to that of ants, and the young silkworm mainly feeds on mulberry leaves, it mainly needs to molt four times from the young silkworm to the silkworm cocoon, and the growth rate of the young silkworm after four times of molting is accelerated, the body length can reach 6-7 cm, and its appetite will be reduced.

3. Pupa

Young silkworms will first spit out the silk, so that the silk is bonded to the cocoon, and then spin the silk to connect the surrounding branches, so as to form a cocoon support, and the silkworm cocoon will become a pupa about 4 days, the shape of the silkworm pupae is similar to a spindle, divided into three parts: head, chest and abdomen, wait for about 14 days, the silkworm pupae will become soft.

4. Adults

The adult silkworm is also known as the silkworm moth, its shape is similar to that of a butterfly, and there are white scales on the body, but the wings of the silkworm moth are smaller, and there is no ability to fly, its head is round, with compound eyes and antennae, and the female moth can lay about 500 eggs in one night, and after laying eggs, the female moth will die.
