The life cycle game of a silkworm for kids to use to practice. Interactive online diagram for students.
The life cycle of a silkworm lasts six to eight weeks. During the first two weeks of life, a female silk moth produces eggs. The larvae incubate these eggs, which eventually develop into the adult silkworm. The pupa is a stage in the silkworm's development that is crucial in the fabrication of expensive cloth. This happens because it begins to spin the protein fiber that we know as silk thread. After the pupa is fully developed, the caterpillars form a cocoon.
From the eggs, the silkworm's life cycle begins with its pupa, which is a soft, yellow or white cocoon. After molting a first time, the imago emerges from the cocoon. It changes into an adult moth. This moth is smaller than its mature female or male counterpart and lacks wings. It also lacks the ability to fly and feed, and will die after the silkworm has laid eggs. During the pupa stage, the moth spins silk thread around it to protect itself in a cocoon.
During the second stage, the cocoon is unwound. The moth then enters into the pupa stage. As the silkworm larva grows into a mature adult, it will molt 1-3 times before it will create a cocoon. The moth will spin a new cocoon each time, which is a two to three-meter long thread shell. The pupa is a hard-shelled ovum that is protected from predators by an external exoskeleton.
The pupa will begin to produce a pheromone called bombykol. After the second molt, the silkworm will become an adult. After this, it will begin to molt a fourth time.
The larva of the silkworm goes through five larval stages, with the third stage being the pupa. The cocoon contains 12 segments, but the male is smaller. The female releases pheromones to attract the male. The male then mates with the female, and the life cycle of the silkworm continues. It will go through four stages before becoming an adult. The fourth stage is the adult stage. The cycle will keep going on and on as long as the adult moths are fertile and ready to reproduce.
After reading through the life cycle of this interesting insect, I hope you now understand the important role its silk played in the silk road. Silk was historically one of the important sources of silk thread out of which expensive cloth materials were created. It is still used until this day in spite of the fact that other sources of fiber like cotton and wool have become dominant. Play this interactive online game on the life cycle of this organism and tell us what you think.
