What is a significant characteristic of larva compared to adult insects?

The significant characteristic of larvae compared to adult insects is that larvae often look very different from the adults. This difference in appearance is commonly referred to as "complete metamorphosis," which many insects undergo. In this process, the larvae typically have different feeding habits, habitats, and body structures compared to their adult forms. For instance, caterpillars (larvae of butterflies) are elongated and primarily focus on eating, while adult butterflies have wings and take to the air.

This stark contrast aids in minimizing competition between the juvenile and adult stages, as they can occupy different ecological niches and reduce resource competition. Such differences might include variations in body shape, size, color, and even locomotion, making it essential to understand these distinctions when studying insect life cycles and behaviors.
