Does All Silk Come From Silkworms
Although only the silk of moth caterpillars has been used for textile manufacturing, silk can be produced by several insects such as hymenoptera (bees, wasps, and ants), silverfish, mayflies, thrips, leafhoppers, beetles, lacewings, fleas, flies, and midges. In general, silk is mainly produced by the larvae of insects undergoing complete metamorphosis. However, some insects such as raspy crickets produce silk throughout their lives. Besides, some other types of arthropod such as such as spiders also can produce silk.
