答案     The diagram shows that the life cycle of a butterfly can be broadly divided into four stages.
    At the first stage, female butterflies lay eggs on plants, after mating with male butterflies. It is followed by the second stage, which lasts for two to three weeks. At this stage, inside each egg is an embryo, which develops into a caterpillar eventually.
    The third stage is the longest, taking two months, during which time the caterpillar grows gradually until it is fully formed. This stage ends with a two-hour-long process in which the caterpillar creates a pupa. At the final stage, known as the pupal stage, the pupa grows for around two weeks before emerging into an adult butterfly. Adult butterflies fly and mate, marking the end of one cycle and the start of the other.
    Overall, the lifecycle of a butterfly consists of four distinct stages and there are remarkable changes in the appearance of the insect in different stages.
