Those precious silk garments in your closet were made by the caterpillar of a fuzzy white moth - thousands of them. Silkworms spin a cocoon with a single strand of silk up to ten city blocks long. Humans have bred these insects into weaving machines that can no longer survive in the wild.

-
The sumptuous silk in your satiny sheets and glamorous gowns comes from humble beginnings - a caterpillar of the domesticated silk moth. For almost five thousand years, people have raised silkworms for their unique, shimmering material. In just a few days, these caterpillars produce one fine thread of silk one kilometer long, and intricately weave it into their cocoons.
For most silkworms in captivity, this is where their journey ends. To preserve the integrity of the continuous silk thread in each cocoon, silk farmers kill the pupa inside the chrysalis by boiling, steam, or sun. Then the strands are loosened in hot water and unwound by hand using specialized spinners and silk harvesting tools. This raw silk is then gathered onto large spools and refined into commercially valuable threads. It can take up to 2000 silkworms to make one silk dress.
Today, the silk industry is valued at more than $10 billion globally, but it is more than just a luxury item. Silk is pound-for-pound stronger than steel, and it is now used in medicine to heal bones and tendons. Our five thousand year love affair with this extraordinary material continues to hold silkworms captive -- until we learn to spin silk better than they can.
__
- What other insects produce silk?
Animal-produced silk is actually quite common in the natural world. Spiders (of course), fleas, webspinners, caddisflies and even some ants and bees make silk. But only the silk made by the caterpillar of the domestic silk moth is widely cultivated by humans.
- Are silkworms edible?
Yes! Silkworms are enjoyed as a nutritious snack in many countries, including Thailand, Vietnam, China and Madagascar.
- Where do wild silk moths live?
Domestic silk moths (Bombyx mori) can’t survive in the wild without help from humans, but their cousins - the wild silk moth (Bombyx mandarina) can be found in Asia, in countries like China, Korea and Japan.

As a kid growing up in Japan, we called silk worms (kaiko in Japanese) as Kaiko-Sama. We use -sama as a way to address those whom we revere or regard highly of, such as divine entities and honorable people. I think ancient people started calling the silk worms with an elevated address to show gratitude to the silk moths and worms. It’s a curious relationship, and I’m sure they were aware of it - to harvest unbroken silk, they had to boil them, which is a cruel practice; for the precious silk obtained in exchange for their lives, they showed reverence and gratitude to them.

Now I don't know what would become of the pupae once they've been boiled in an industrial silk manufaturing setting, but in small-scale silk manufacturers in Vietnam they would be stir-fried with spices and chopped lime leaves to be served as a delicacy.

From googling around, I found out that the silkworms are too small, and after boiling, they would become moist. And not to mention about their uncleaned innards. So they won't be really tasty to eat. That being said, they might still be used as chicken feed (this part is just my idea).

@tosyl_chloride Жыл бұрын

@@renseiryuu Tbf, the innards only comprise of mulberry leaves' digested remains, so it's relatively "clean" - not like you'd be dealing with rotting insect corpses in their guts anyway. And of course they wouldn't be eaten straight after boiling - I don't think anyone would want to eat that kind of squishy and bland bugs. In my experience, they would be stir-fried or roasted with seasoning until dry - by then they would have a powdery and savory texture. A spoonful scoop of these into your bowl of rice, and you have a delicacy. Additionally, there's an option to roast the boiled pupae until they get charred black; this would give them a different bitter taste, but is not recommended (as it doesn't taste very well, on top of being carcinogenic)

@Zaxares Жыл бұрын

There are some companies which produce silk that do not kill the moths in the process, but the downside is that, as Lesley says in the video, the moths chew their way out of the silk cocoons, so this breaks the thread which means they can only produce shorter lengths of silk, which fetches a lower price. It's also worth noting that, as the video says, once they hatch, the moths only have a few days to live anyway. What's more, in the wild, the vast majority of these moths also wouldn't make it, being eaten by predators. The dead moths also don't go to waste; they're turned into fertilizer or animal feed. So, at the end of the day, if you still prefer your silk from a source that doesn't involve killing the silkworms, there are options available so go for them. :) But in the bigger picture, the moths were always destined to die anyway, and their deaths are usually quite quick. They also live carefree lives with plenty of food and no predators, probably in better settings than most of our domesticated animals that we rear for food.

So many commenters feeling bad for the moths, but you have to keep in mind that they spend the majority of their lives as caterpillars gorging themselves. Did you not hear the part about the adults having only a few days to live? That's not something humans bred into them, that's their natural life cycle. The moths don't even eat. Their only purpose is to fly around until they find a mate, and with humans to do that part for them they don't even need to fly.

@melissapetricini6706 Жыл бұрын

Odd that these moths only have a few days when other more wild silk moth species (like the Luna Moth) live up to a week. They also have no mouths and change only to mate. They also call the male "flightless". That is not the case with wild moths like the loss of color they mentioned. Captivity breeding has weakened them as a species.

@JossOwX Жыл бұрын

They are also under human care so they dont have to compete and get exist in the wild Their species will continue to live as long as humans live and use them. Life's goal is to reproduce and survive and they're meeting that through us

Kinda pointless given that in the wild the numbers dead from predation or lack of food pretty much would be as high or higher. The fact they die within a few days of life kinda shows that in the end it doesn't really matter. Better to harvest them as is in the cocoon well they sleep as thousand more will survive to continue to the next generation.

I think the people that assume the silkworms suffer aren’t looking at the whole picture. For one, the silkworms and the moths live carefree lives in the farms. They’re provided ample food, live in an environment without harsh conditions, and are protected from predators and disease. While it is kinda sad the moths cannot fly, they’re otherwise completely fine, you must remember many moth species die very quickly once they turn into adults, as they emerge without mouthparts. There’s also methods of harvesting silk that don’t kill the pupa. They’re not as common as the silk is damaged, but they’re prevalent and something worth noting. Pupa that are killed in the process don’t go to waste, either. They’re edible and a delicacy in many countries. And IIRC they make for good compost, too.
