Different stages in the lifecycle of silkworm moth is depicted in the given diagram. Overall, silkworm moth undergo around six stages in it's entire life span of 6-8 weeks. The adult female and male silkworm moths mate each other and after the female one lay around 500 eggs on the mulberry leaves. These eggs hatched into larvae in 10 to 25 days. Their main food is the mulberry leaves and for their survival, the moderate temperature level is about 23-28 degree celcuis and humidity is between 85-90%.
After 23 to 25 days, the larvae becomes pupa by covering with silk thread produced from it's own salivary gland: the envelope is called as cocoon and this can produce nealy 500m raw silk thread. This pupa phase remains for 10 to 12 days, during this period the pupa becomes moth. After 12 days the fullly grown adult moth emerges out of the cocoon.
