These magnificent creatures live only for less than ten days as a winged adult after spending almost 11 to 12 months for metamorphosis. Depending upon the availability of food and climate, each instar (the period between 2 molts) may take anywhere between 4 to 10 days. Under normal weather conditions, the pupal stage will be over in 2 weeks but that is not the case in winters. Once they go through their pupae stage and emerge as an adult, the primary purpose of this insect is to reproduce.
