What type of metamorphosis do beetles undergo?

Beetles undergo complete metamorphosis, which is characterized by four distinct life stages: egg, larva, pupa, and adult. This process allows for significant changes in form and function as the organism develops.

In the egg stage, the beetle begins its life cycle, after which it hatches into a larval form often referred to as a grub. This larval stage is primarily focused on growth and feeding, allowing it to accumulate the necessary energy and resources for the transformation to the next stage. Following this, the larva enters the pupal stage, during which it undergoes a remarkable transformation within a protective casing. This stage is crucial as the organism reorganizes itself, and significant physiological and structural changes occur. Finally, it emerges as an adult beetle, fully formed and ready to reproduce.

This type of metamorphosis, complete metamorphosis, contrasts with incomplete metamorphosis (found in insects like grasshoppers and cockroaches), which involves only three stages: egg, nymph, and adult, with the nymph resembling a smaller version of the adult and undergoing gradual changes without a distinct pupal stage. Therefore, recognizing the complete metamorphosis of beetles helps in understanding their life cycle significantly
