Silk is a natural protein fibre, some forms of which can be woven into textiles. The protein fibre of silk is composed mainly of fibroin and produced by certain insect larvae to form cocoons. The best-known type of silk is obtained from the cocoons of the larvae of the mulberry silkworm Bombyx mori reared in captivity (sericulture). The shimmering appearance of silk is due to the triangular prism-like structure of the silk fibre, which allows silk cloth to refract incoming light at different angles, thus producing different colors.
Silks are produced by several other insects, but generally only the silk of moth caterpillars has been used for textile manufacturing. There has been some research into other silks, which differ at the molecular level. Many silks are mainly produced by the larvae of insects undergoing complete metamorphosis, but some adult insects such as webspinners produce silk, and some insects such as raspy crickets produce silk throughout their lives. Silk production also occurs in Hymenoptera (bees, wasps, and ants), silverfish, mayflies, thrips, leafhoppers, beetles, lacewings, fleas, flies and midges. Other types of arthropod produce silk, most notably various arachnids such as spiders (see spider silk).

Famous quotes containing the word silk:
“Come, let me sing into your ear;
Those dancing days are gone,
All that silk and satin gear;
Crouch upon a stone,
Wrapping that foul body up
In as foul a rag....”
—William Butler Yeats (1865–1939)
“O bid me mount and sail up there
Amid the cloudy wrack,
For Peg and Meg and Paris’ love
That had so straight a back,
Are gone away, and some that stay
Have changed their silk for sack.”
—William Butler Yeats (1865–1939)
“Her fortune, too, lies there,
Converted into cool hard steel
And right red velvet lining;
While over her tan impassivity
Shot silk is shining.”
—Gwendolyn Brooks (b. 1917)
