Which of the following insects undergoes complete metamorphosis?

The correct choice, beetles, undergo complete metamorphosis, which consists of four distinct life stages: egg, larva, pupa, and adult. This process allows for significant changes in form and structure between the stages. Beetles, as members of the order Coleoptera, exhibit this complete metamorphosis, starting from a small egg that hatches into a larva. The larval stage is often quite different in appearance from the adult, and it then transforms into a pupa, where it undergoes significant changes before emerging as an adult beetle.

In contrast, dragonflies undergo incomplete metamorphosis, which involves only three stages: egg, nymph, and adult. Termites also exhibit incomplete metamorphosis, going through egg, nymph, and adult stages, where nymphs resemble small adults but do not undergo the drastic transformation seen in complete metamorphosis. Similarly, ants undergo incomplete metamorphosis, with a life cycle that includes egg, larva, pupa, and adult stages, but as larvae, they share more similarities with the adults compared to beetles' larvae. Understanding these differences in life cycles is crucial in pest control and entomology, especially in recognizing pest life stages for effective
