Silkworms come from the eggs of the silk-moth (Bombyx mori). The eggs are about the size of mustard seed. When first laid, they are yellow, afterward they change to a dark slate-color. As worms, they have five ages, one is the chrysalis, and one as the miller; so we may say truly, the silkworm has seven ages.

When the worms are first hatched from the eggs, they are about an eighth of an inch long, all covered with black hairs, that fall off in a few days. The head is black and shiny.

When the worms are nearly ready to come out of the shell, by the use of a magnifier the worm may be very plainly seen coiled round the outer edge of the shell. One black spot shows very conspicuously. That is the head of the insect. The eggs are slightly depressed in the center after the vitalized particles concentrate round the outer edge of the eggs to form the bodies of the worms. When the moment of perfect maturity arrives, the worms burst a little hole in each shell, and crawl out head first. They immediately seek food. The great cycle of silkworm life (i.e., from the egg to the egg again) is from thirty-six to forty-six days. When about four days old, they pass into a kind of sleep, called molt, in which the condition they remain twenty four hours, when they are said to molt, that means, throwing off the entire old skin. They first throw off the head-covering, and then crawl out of the body skin, which remains attached to the leaves or tray where they were when resting during the molt, or slumber. While in the first molt, worms look like bits of rusty wire.

As they come out of the comatose state, the body is a silvery gray, and the head a light brown. This is the second age. Very soon after molting they require food. They continue to grow rapidly for five days more, and then again relapse into a comatose state and wake to the third age.
