Insects with which type of metamorphosis have both a larval and dual stage?

Insects that undergo complete metamorphosis transition through four distinct life stages: egg, larva, pupa, and adult. During this process, the larval stage is significantly different in form and function from the adult stage. The larval stage often appears worm-like and is primarily focused on feeding and growth, while the adult stage takes on a completely different form, which is usually more specialized for reproduction and dispersal. The pupa stage serves as a transformative phase where the insect undergoes substantial changes to develop into its adult form.

In contrast, the other types of metamorphosis have different life cycle stages that do not include both a larval and a distinct second stage like the pupa. For example, simple, gradual, and incomplete metamorphosis involve fewer distinct life stages, often leading to adults through a process of gradual change rather than a distinct larval and pupal stage. This characteristic of complete metamorphosis underscores its complexity and the dramatic changes the insect undergoes, which is why it is the answer to your question.
