Holometabolous development is a type of insect life cycle that includes four distinct stages: egg, larva, pupa, and adult. In this process, the insect undergoes complete metamorphosis, where the larval stage looks entirely different from the adult. This allows for specialization in feeding and habitat during the larval stage, while the adult stage focuses on reproduction. During the pupal stage, the insect undergoes significant transformation, reorganizing its body structure. This stage is crucial for developing the features of the adult, such as wings and reproductive organs. Common examples of insects that exhibit holometabolous development include butterflies, beetles, and flies.
