life cycle of silkworm project

Egg is otherwise known as ‘Ova’, the initial phase of silkworm life cycle. This way, they unwind the silk thread from the cocoons. The female silk moth lays about 300 to 400 eggs at a time. The eggs hatch and the caterpillars or silkworms emerge. Finally, after completing pupa stage, the beautiful adult moth comes out of the cocoon. I recently found this artificial ivy trellis from Kmart (Australia), which makes a really awesome backdrop for science centers. A few years ago, I studied silkworms with the kids in my class and they loved it! The process of collecting cocoons and harvesting them to produce silk is known as sericulture. Life Cycle of a Silk Worm Most commercial silk is Mulberry silk that is produced from cocoons of the Mulberry silkworm moth,called Bombyx mori, and comes mainly from China and India. The larva stage is the most active stage of life cycle of a silkworm. 3. So, place this structure at this stage. This stage is also known as vegetative stage, where the larva grows by feeding on mulberry leaves. The pupa stage is the most significant and motionless stage seen in holometabolous insects. The female silk moth lays eggs usually during summer season but becomes inactive until the arrival of spring. Eventually, they start building protective layer made of silk threads in order to protect from predators. The interesting and saddest part of this stage is: male adult dies soon after the process of mating. You can learn more about the other activities here. More than a few caterpillars gather to form this protective layer. That is the reason, the term ‘silk’ is generally referred as the silk harvested from the silkworm, Mulberry. I had a hard time finding suitable resources a few years back, so hopefully these will help! The following bulletin board is an engaging way to introduce kids to the life cycle of a silkworm.
