Newly-hatched silkworms: When just hatched from eggs, their body is brown or russet, tiny, and fuzz, looking like ants, so they are also called ant silkworms. Ant silkworms are about 2 mm long, 0.5 mm wide. After they leave the shells, they begin to eat mulberry leaves 2-3 hours later.

Newly hatched silkworms-matured silkworms: Silkworm babies eat a lot, therefore, they grow fast with body color gradually becoming weak. But sometimes their appetite gradually wanes and even fast. Vomiting out a small amount of silk, fixing gastropod on rearing bed, raising cephalothorax, resting as if asleep, this period is known as "Dormant Period". Silkworms in this period seem motionless, but their bodies are preparing for peeling. It’s also called “Aging”, showing the silkworms are in a certain development stage. The first aging is when ant silkworms peel for the first time; They are in the second aging period when they are awake; It’s the third aging period when they peel again; When they peel for the third time, whey enter into the fourth period, the fourth molting is also called “Long sleep”; Just after the long sleep, it’s the fifth aging period. Silkworms grow very fast in this period, their body can be up to 6-7 cm long, weighing about 10000 times heavier than the newly-hatched silkworms.
