The diagram illustrates the life cycle of the Monarch butterfly. Overall, it is clear that this circular process, common in nature, can be divided into four main stages: egg, larval, pupal, and adult.
With regard to the first two phases, it is evident that the life cycle starts after the mating of two adult butterflies, who then lay eggs on the milkweed. After two weeks, the larva hatches; following that, it develops into a caterpillar and attaches to the milkweed, preparing for the next stage.
Over the 10-day period, the chrysalis forms, which signifies the beginning of the pupal stage. The insect then emerges from the chrysalis; subsequently, the adult migrates to the south and, after half a year, travels to the north, where they can mate with another specimen to lay eggs and start the process all over again.
