Most commercial silk fiber is produced by silkworms, a kind of caterpillar native to China. The silkworm is a fussy eater; in fact, it dines on nothing but:
A) Bamboo shoots B) Eucalyptus bark C) Mulberry leaves ü D) Orchid nectar
The silkworm is the larval stage of the moth Bombyx mori. It is the only phase of the moth’s life cycle in which it eats at all, but it does so with great enthusiasm, consuming tens of thousands of times its own weight in leaves over the course of four to six weeks. At the end of this time, the silkworm settles down to the task of producing silk — up to 1,500m (5,000 ft) of continuous thread — and constructing a cocoon from it. After a fortnight or more inside the cocoon, the creature emerges as an adult moth, ready to mate, reproduce and die.
