Weight of Average Silkworm: Growth and Reproduction of Silkworms

Bombyx mori, the cocoon of silkworms, belongs to the order Lepidoptera in the phylum Arthropods. Its larvae, which feeds on mulberry leaves, are cultivated for the production of silk (sericulture) and are therefore very important economically. find out more weight of average silkworm: growth and reproduction of silkworms.


What are silkworms?

a moth whose larvae spin strong silk in large quantities in building its cocoon mainly: the Asian moth (Bombyx mori of the family Bombycidae) whose coarsely hairless caterpillars produce trade silk.


What is the relationship between silkworms and silk?

The relationship of caterpillars with silk fabric is caterpillars produce fibers that are used as materials for making silk fabrics. Caterpillars produce natural protein fibers derived from the cocoon of the larvae of mulberry silkworms.


Who invented the silkworm?

The history of the SilkWorm, as well as the story of the Sutra, goes back to ancient times in China. The most common story of the silkworm’s origins begins in 2640 BC when Si-Ling-Chi, a Chinese Empress only strolled through her garden when a ‘cocoon’ (silkworm) fell into her tea.


Can silkworms fly?

Silk moths can not fly, since thousands of years are kept, but male silk moths can leave containers/shoeboxes when looking for female mates. Some males may almost fly if you drop it from a small height, but it is out of control, and they will touch the ground after a while.

How do I distinguish male and female silkworms?

It is easy to separate the male and female silk moths, where the female moth has a larger abdomen and the male has a smaller abdomen. Males also tend to be more active, as they continue to search for a mate.

Moths live quite soon 5-10 days, with men generally outlive girls. The silk moth will start to search for a mate when it comes from its cocoon, with a few observed mating with the moth of the other gender within its cocoon when two moths discuss one!

After mating, the Female Moth will lay between 300-500 eggs, then die, while the male Moth will look for another mate if it is not too old.

It also weighs not much, only about 5 grams or a little under 2 ounces. Silkworms from the Bombyx mori moth, which produces the best and purest silk, are fed a food consisting only of cut mulberry leaves.

After mating, the female silkworm moth lays small eggs on the leaves of mulberries. Moth caterpillars that do not eat or drink in the final stages of their life cycle, mate; the female lays eggs and the adult moth dies. In locations where the seasons shift, silkworm moths replicate just once every year.


How many silkworms does it take to produce 1kg of silk?

While we’re turning silk, the truth: It requires 5,500 silkworms to make 1 kilogram (2.2 pounds ) of raw silk. A silkworm rotates a cocoon around itself in three to four days, and 2,500 to 3,000 cocoons are needed to make just one page of silk woven fabric.


How big are silkworms?

Mature silkworms have a wingspan of 40 to 50 mm (about 2 inches) and possess a thick hairy figure (mature females are bigger than adult men ).

How much do silkworms eat every day?

As you can guess, small silkworms do not eat as many old worms. The leaves must be inserted at minimum one time daily, and two-three times every day once the silkworm reaches total size – after in the morning, after at the center of the afternoon, and after bed (in case the day is warm and the leaves wither, swap the leaves) around more frequently ).

What is the life cycle of silkworms?

The total life cycle of silkworms ranges from 6-8 weeks. Generally, the warmer the weather, the faster the life cycle of silkworms, but other factors such as humidity and sun exposure are also very important.

Ideally, silkworms will experience 12 hours of sunlight, and 12 hours of darkness per day, temperatures of 23-28 degrees Celsius, and humidity levels of 85-90%.

Under such conditions, your eggs should hatch within 7-10 days. However, it is very difficult to achieve these conditions without an incubator, and it is common practice to simply adjust to the weather in the area where you live.



In Australia, silkworms will naturally hatch in late July to early August : depending on the weather in which you live – this time amazingly coinciding with the Mulberry Tree regaining its leaves after the tree loses its leaves in Winter.

I suggest you keep all the eggs in the fridge to hatch at a predetermined time. Silk eggs will hatch if exposed to heat.

  • Eggs: 10-25 days
  • Lava and worms: 20-33 days
  • Cocoon: 10-14 days
  • Moth: 5-10 days


Lava / Cocoon

After 20-33 days of constantly chewing Mulberry leaves or food, silkworms will feel the desire to become a cocoon. Within the cocoon, the silkworm will alter feathers for the previous time, since it means that the previous point of its life span to develop into a moth.



After 10-14 days it develops into a moth in its cocoon, a silk moth will appear from the cocoon and will secrete a brownish-colored liquid upon its appearance – do not worry, this is completely normal, and is a sign of the presence of silk moths. cleaning the system.


Facts of silkworms

Domesticated silkworms

Silkworms were selectively bred for centuries because they have been discovered. This implies most silkworms are observed on silkworm farms rather than at the wild. The industry is annually worth about $200-500 million. In addition to bees, silkworms are the only insects that humans tame.

SilkWorms Eat Only Mulberry Leaves

Rich in minerals and vitamins, mulberry leaves possess the nutrients silkworms need. Silkworms, after hatching eat wildly, feed on about 50 times the weight of mulberry leaves.


SilkWorms Lay Up to 300 Eggs

The female silk moth will lay up to 300 eggs at a time. He will soon die after laying eggs because adult silkworms have a small mouth so can not eat.

In about two weeks, these eggs will hatch into larvae under favorable conditions.


China’s Secret Silk Industry

Cultivated in secret, silkworms and silk making have remained on China’s borders for more than 1000 years.

As a valuable product, silk was traded along the Silk Road stretching from China, through West Asia to Rome.

It was only in the 6th century when Byzantine monks smuggled silkworm eggs.


Natives of Northern China

During ancient China, they began to be cultivated for their silk. Around 2696 BC, the Yellow Emperor’s wife discovered a silkworm cocoon that fell into her tea. He noticed that the cocoon was made of strong but soft thread.

She devised silk looms and educated other girls how to mix these threads to cloths. Silk was highly valued in ancient China, only the royal family and the noble class were allowed to wear it.


One Cocoon Can Be 300-900m Long

Silkworms produce cocoons made of a thread of raw silk through its saliva. This thread can be 300-900 meters long, circling its body 300,000 times.

Approximately 2,000 – 5,000 cocoons are essential to earn 450g of silk.

If the silkworm is allowed to mature, it will make a hole from the inside to escape as a moth.

It ends up cutting the silk thread. This means that most silkworms are steamed and discarded before this happens.


Facts of silkworms for children

Especially for children, silkworms can be a great pet.

Maintained as a hobby, keeping silkworms with fresh mulberry leaves or artificial food can educate.

This is a good opportunity for children to learn about the life cycle of insects.

With a life cycle of about 2 months, they can also create great class projects.
