What are the sources of silk?
Silk is produced by silkworms, which are the larvae of silk moths. The silkworms create silk fibers by secreting a protein called fibroin through their salivary glands, which solidifies when it comes into contact with air. The fibers are then collected and spun into silk threads.
What is the length of a caterpillar using centimeters?
The length of a caterpillar can vary widely depending on the species. Generally, most caterpillars range from about 2 to 10 centimeters in length, although some can be larger. For example, the larval stage of the giant silk moth can reach up to 15 centimeters.
Why are silk nylon and fiber soft?
Silk, nylon, and other soft fibers are characterized by their fine, smooth textures and flexible structures. Silk is a natural protein fiber known for its luxurious feel and luster, while nylon is a synthetic polymer that can be engineered to be soft and lightweight. The softness of these materials is due to their molecular composition and the way the fibers are spun, allowing for a comfortable drape and touch. Additionally, their ability to absorb moisture contributes to their soft, pleasant feel against the skin.
Butterflies liquefy in cocoon?
A butterfly does not spin a cocoon, it's pupa is called a chrysalis. A moth, however, spins a protective silk case which is known as a cocoon. A caterpillar spins either a cocoon or a chrysalis depending on its breed. After being incased it will be its transfirmation into a butterfly. The time spent in the chrysalis is different for each species of Butterfly, but when the metormorphosis is complete the new butterfly will break its way out of the casing of the chrysalis and spread its new wings for the first time. The butterfly will genrally cling onto the side of the chrysalis for an hour or so, to allow their wings to dry out, and enable them to fly for the first time. The time that a lava spends in pupation may be brief, as with the Monarch butterfly who only stay in a chrysalis for 2 weeks. However, some species enter into a dormant state when they start pupation and stay in this stage until the appropriate season. They mostly stay dormant through the winter months or during the dry season in the tropics.

What is the casing spun of silk by catterpilars?

What is is a Caterpillar?
A caterpillar is the larva stage of a butterfly or moth. A caterpillar hatches from the eggs of a butterfly or a moth. After a given amount of time, it then forms a cocoon, a casing of filament spun from its own silk glands. The caterpillar remains in this cocoon for protection while its body transforms into a butterfly or moth.

Why is a brown cocoon stuck to the wall?
A brown cocoon is stuck to the wall because it is the protective casing spun by a caterpillar before it transforms into a butterfly.
Is silk living nonliving or never part of a living thing?
Silk is non living, for it does not reproduce, respire, or metabolize. It was once part of a living thing, the silkworm caterpillar, which spun the fibre of which the caterpillar made its cocoon. From this cocoon the silk strand was unspun to give us the silk thread.
Is silk made from a plant or an animal?
Silk is spun for the cocoon of the silkworm, an insect, before it can turn into a moth. It's vaguely similar to spider web. The silkworm is fed on mulberry leaves.
Is silk from plant?
No. Silk fibre is spun by silkworms as cocoons.
Where does silk really come from?
silk comes from a silk worm, which is harvested and spun to create silk.
Is a silk worm a caterpillar?
no
The production of silk?
Silk is spun from the fibres of the cocoon of the mulberry silkworm, the caterpillar of a type of moth. There are other species of bug which produce workable silk, but aren't generally used for textiles, though research continues. Commercial silk is strong, easily dyed and wonderfully reflective of light. So the short answer is, silk originates from a caterpillar's bottom. Did you really want to know that?
What is the casting spun of silk by caterpillars?
cocoon
Is there a silk-cotton tree?
No. Silk-cotton is a man-made blend of Silk and Cotton. * Cotton is spun from the flowering seed heads of the cotton plant * Silk is spun from the cocoons of silkworms, which feed on leaves of the mulberry tree
