What are the steps in the process of complete metamorphosis?

The process of complete metamorphosis in insects is characterized by four distinct life stages: egg, larva, pupa, and adult. This transformation begins with the egg stage, where the insect embryo develops. Once the egg hatches, it enters the larval stage, which is often a feeding and growth phase. Larvae typically look very different from the adult form and are primarily focused on consumption and growth.

After the larval stage, the insect enters the pupa stage, during which it undergoes significant transformation. This phase is often a time of dormancy, where the larva reorganizes structurally to become an adult. Finally, the adult stage emerges from the pupa, fully forming the characteristics of the mature insect, ready for reproduction.

The inclusion of all four stages in the correct answer outlines the comprehensive process of complete metamorphosis which is crucial for understanding insect development and the various life cycles that can influence pest management strategies in structural pest control. Understanding each stage is vital for diagnosing and effectively controlling wood-destroying pests.
