Final answer:
The correct order of stages in a blowfly's life cycle consists of egg, larva, pupa, and adult, showcasing an example of complete metamorphosis where each stage has specialized adaptations.
Step-by-step explanation:
The life cycle of a blowfly follows a process of complete metamorphosis, which includes four distinct stages: egg, larva, pupa, and adult. Initially, the female blowfly lays eggs on decaying matter, which then hatch into larvae, commonly known as maggots. These larvae feed and grow until they enter the pupal stage, where they undergo a significant transformation within a cocoon-like structure. Finally, they emerge from the pupa as fully formed adults, ready to continue the cycle of life.
This extraordinary process of metamorphosis allows the blowfly's life cycle to be divided, with each stage evolving distinct adaptations suited to its specific role, without affecting other stages. The larval stage is primarily for feeding and growth, the pupal stage for transformation, and the adult stage for reproduction and dispersal.
