The given chart demonstrates the life cycle of a butterfly. Looking from an overall perspective, it is apparent that the cycle comprises of total 4 stages, commencing with egg laying.
Moving to the details of the chart, the first stage involves mating of adult butterflies followed by the process of egg laying by female butterflyon a plant. Then, in the next stage, eggs convert into embryo and development of the embryo begins that takes 2-3 weeks to complete. Here, each egg develops one embryo and transforms the embryo into a caterpillar.
Probing ahead, in the third stage, caterpillars grow their size and length via skin-shedding that lasts for two months. Now, the caterpillar converts into a pupa in 2 hours and the pupa encloses itself in a shell. Finally, in the last stage, pupa enters the pupal stage and stays in this phase for 14 days where metamorphosis occurs. Once metamorphosis completes, the pupa enters its adulthood, which is then ready to reproduce. Hence, the cycle continues.
