Do Silkworms Make Silk

Does silkworm make silk?

Yes! Silkworms are offspring of moths. Silkworms spew out a substance called fibroin from small holes in their jaws. And the spewed-out substance not only contains digested leaves but also protein produced by the worm. The silkworm produces between 500-1200 silken threads within a 72 hour time period, creating a soft and silver cocoon. Each cocoon produces approximately one kilometer of silk fiber. However, once the silkworm completes its cocoon, silk farmers remove the cocoon with steaming water and carefully unwind the cocoon fibers.
