What type of metamorphosis do Powderpost beetles undergo?

Powderpost beetles undergo complete metamorphosis, which consists of four distinct life stages: egg, larva, pupa, and adult. This type of metamorphosis allows for significant changes in form and function throughout their development.

In the egg stage, females lay their eggs in or on wood. The larval stage follows, where the larvae burrow into the wood and feed, causing damage as they develop. After a period of growth, the larvae enter the pupal stage, during which they undergo transformation in a protective cocoon. Finally, the adult beetle emerges from the pupal stage, ready to reproduce and continue the life cycle.

This contrast in stages highlights the differences between complete and incomplete metamorphosis. In incomplete metamorphosis, for example, insects develop through fewer stages and often hatch as nymphs that resemble smaller versions of the adult, rather than undergoing a transformative pupal stage. Thus, the classification of powderpost beetles as undergoing complete metamorphosis is accurate and aligns with their lifecycle characteristics.
