\ that Silkworm (Bombyx mori, Latin for “silkworm of the mulberry tree") is, technically, not a worm? It is the caterpillar of a moth.

that it takes up to 20 pounds of cocoons to obtain 2 pounds of silk? About 2,000 to 3,000 cocoons are required to make a pound of silk. One pound of silk represents about 1,000 miles of filament.

that silk is much lower in density compared to cotton, wool or nylon? It is, therefore, highly moisture absorbent, able to absorb as much as a third of its own weight in moisture without feeling damp.

Silkworms are tiny worms that spin their own silk cocoons. The scientific name for silkworms is Bombyx mori, which means “silkworm of the mulberry tree.” They have been raised to produce fabric for thousands of years and can no longer be found in the wild.

Silkworms begin as wormlike larvae with the three distinct body parts of an insect. After spending time in a cocoon, the silkworm morphs into a scaly, four-winged moth.

After hatching from eggs, the worms molt four times before spinning their cocoons. The silk fiber comes from the cocoons.

Silkworms eat the leaves of the mulberry tree or can exist on an artificial diet. They also eat the leaves of the tree known as the Tree of Heaven.

Silkworms now depend on silk producers, laboratories and schoolchildren to propagate the species. In their domestication, the moths lost the ability to fly, so wild populations no longer exist.

Female moths release pheromones that are picked up by tiny hairs on male moth antennas. The small amounts of pheromones are detectable from long distances.

Silkworms also known as domesticated silk moth and Bombyx Mori ('Silkworm of the Mulberry Tree' in Latin), is the insect from which silk is produced. One of the first products in the world to get the 'Made in China' tag is silk! Silk has been cultivated in China from ancient times and traded world wide ever since.

The silkworm (Bombyx mori) is the larva or caterpillar of the Bombyx mori moth. Silde for at least 5000 years in China. The moth is important because it makes the silk, and no longer lives in the wild. It is entirely dependent on humans.

The silkworm life cycle goes through the larva-cocoon-moth stages, which are typical of most moth-like insects. Here are some interesting facts about silkworms and their life cycle.

The cocoon is made of one thread of raw silk from 300 to 900 meters (1000 to 3000 feet) long. The fibers are very thin. About 2,000 to 5,000 cocoons are needed to make a pound of silk.

The silkworm eggs, laid out about 300 to 400 at a time, generally take about ten days to hatch. Once the eggs hatch, the larvae or bay silkworms eat incessantly and are always famished.
