Govind Life cycle of silk moth

  1. 1. The silk Moth have unique lifecycles. Their life cycles consist of four stages: •egg •larva: caterpillar and silkworm •pupa: cocoon or chrysalis •silk moth or butterfly
  2. 2. History In ancient times, it is said that an empress of China accidentally dropped a silk cocoon into her tea. It began to unravel giving her the idea to use it as a yarn. The earliest mention of silk fabrics is attributed to ancient India and is thought to have been brought to other parts of the world by the Aryans, along with the horse. The symbol for silk was already part of the written language in China around 2600 BC and fragments of ancient silk fabrics have been found and dated back to around 1500 BC. By 200 BC it was so abundant in China that it was used as wages for soldiers. Aristotle first mentions silk in Western culture around 300BC but it was not until the "Silk Road“ trading routes were established around 100AD did silk become abundant in the West. Silk influenced the fortunes of many countries since and is said to be one of the financial bases of the Renaissance. Sericulture, as it is called, or silk production has been established in many countries since but China is still one of the most dominant suppliers of silk to the world.
  3. 3. First Stage: Egg Silkmoth lays hundreds of eggs in neat rows. They may be round like balls or flat like pancakes. And Female moth lays many tiny egg.
  4. 4. Second Stage: Larva The caterpillar or silkworm that emerges from the egg is only about an eighth of an inch long and covered in hair. The caterpillar feeds on the mulberry leaves, going through four separate molts as it matures toward the pupa stage. As it molts, the old skin is shed and a new, larger one is grown. After the first molt, the silkworm loses its hairy exterior and remains smooth and soft throughout this stage of its life.
