उत्तर

Bombyx mori (silk moth) is an insect that enters diapause. 
It enters into diapause due to some adverse environmental conditions such as drought, extreme temperature, reduced food availability; which, in turn, delays the overall development.  The physiological and metabolic activities are also diminished at this particular time.
Thus, it is a type of survival mechanism exhibited by the insect at the time of adversity.
