The birth of the big peacock butterfly has only one task-breeding offspring. The life span of male peacock butterflies is only three or four days, while that of female peacock butterflies is only about seven or eight days.

Their survival time is just the time needed for mating. Male peacock butterflies sometimes can't find a mate in a limited life and can only die silently. Fabers described it this way: "The great peacock butterfly only exists as a butterfly passed down from generation to generation.

It knows nothing about eating. If other butterflies are happy gourmets, flying from one flower to another, opening the spiral organs of their kissing tubes and inserting sweet crowns, then the big peacock butterfly is an unparalleled eater, completely free from the drive of the stomach, and can recover its physical strength without eating.

Its oral organs are just useless decorations, not real operating tools.
