Silkworms

Silkworms are the larvae or caterpillars of silk moths, scientifically known as Bombyx mori. They are the primary producers of silk and play a crucial role in the sericulture industry.

Here are some key characteristics and facts about silkworms:

Life Cycle: Silkworms undergo complete metamorphosis, which consists of four stages: egg, larva (caterpillar), pupa, and adult. The duration of each stage can vary depending on factors such as temperature and humidity.

Feeding Habits: Silkworms are herbivores and have a voracious appetite for mulberry leaves. They are highly specialized feeders and can consume large amounts of mulberry foliage to support their rapid growth during the larval stage.

Silk Production: Silkworms produce silk by spinning a continuous filament made of protein, known as fibroin. The fibroin is secreted from two specialized glands called spinnerets located in the silkworm's head. As the silkworm moves its head in a figure-eight motion, it releases the liquid silk, which solidifies upon contact with the air, forming the cocoon.

Cocoon Formation: Silkworms spin their cocoons to protect themselves during the pupal stage, where they undergo transformation into adult moths. The cocoon serves as a protective casing and is made of a single, long silk thread that can be several hundred meters in length. The cocoon provides an ideal environment for the pupa's development.
