What month do the silk eggs hatch?

Under ideal conditions (78° to 88° F and allowed to feed nearly continuously) silkworms can go from egg to 1 inch in length in about 12 days, and 3 inches in under 30 days. The worms will begin to spin cocoons at about 28 – 30 days old or when they are between 2 1/2 and 3 inches long.

The phase that is particularly important for feeding is the period during which the eggs hatch into larvae. This normally takes 27- 28 days. Silk worms sleep for four times in this phase, and molt during each hibernation. Each hibernation phase (molting) takes around 24 to 48 hours depending on the instars.
Why do they boil the silkworm cocoon?
Cocoon cooking unwinds the cocoon filament spun by the silkworm. The sericin covering around the cocoon filament is agglutinated after silkworm spinning, then hardened through the cocoon drying process. In preparation for reeling, it should be softened. Processing softens sericin by heat, water and steam.
Do silkworms feel pain?
“I put the question to Thomas Miller, an entomologist at the University of California—Riverside, who says that silkworms have a central nervous system, but that they lack structures equivalent to vertebrate pain receptors. ‘Bottom line,’ he says, ‘there is no evidence they experience what you call pain.
