Silkworm pupae can still live after cocoon cutting. Cocoons protect silkworms from harm. Without cocoons, they will not die. The larva of silkworm is called silkworm, which mainly eats mulberry leaves to survive. Like a butterfly, the silkworm moth is covered with white scales, but its two pairs of wings are very small and have no ability to fly. Usually three or four hours after mating, the female moth will give birth to a fertilized egg, which will soon die, and the egg will slowly undergo a new generation of bad cycles.
