Which of the following insects undergoes Incomplete Metamorphosis?

Dragonflies undergo incomplete metamorphosis, which is characterized by three life stages: egg, nymph, and adult. In this process, the nymph stage resembles a smaller version of the adult and typically lives in water. As the nymph matures, it undergoes several molts where it grows larger, eventually emerging as an adult dragonfly. This metamorphosis differs from complete metamorphosis, which involves a distinct pupal stage where the insect undergoes a radical transformation.

Butterflies, on the other hand, undergo complete metamorphosis, consisting of four stages: egg, larva (caterpillar), pupa (chrysalis), and adult. Ants also experience complete metamorphosis with a similar developmental cycle. Beetles follow the same pattern as butterflies and ants, undergoing complete metamorphosis as well. In contrast, the nymphs of dragonflies develop directly without a pupal phase, thereby illustrating the process of incomplete metamorphosis.
