Synopsis

Excerpt from Silk and the Silk Worm

The time from the hatching to the spinning of the cocoons will vary from 30 to 40 days, depending on the race of the worms, quality of food, mode of feeding, temperature, etc but the same proportion of time between the molts is generally found to be the same.
