"caterpillar" 的定义和意义

What is a "caterpillar"?

A caterpillar is the larval stage of a butterfly or moth, characterized by a worm-like body with numerous legs. It is a voracious feeder and primarily feeds on plant leaves. Caterpillars come in various colors and patterns, often camouflaging themselves to blend in with their surroundings. They undergo a remarkable transformation called metamorphosis, where they transition into a pupa and eventually emerge as an adult butterfly or moth. During their larval stage, caterpillars play a vital role in the ecosystem by contributing to plant pollination and serving as a food source for other organisms. Some caterpillars possess defense mechanisms such as stinging hairs or toxic chemicals to protect themselves from predators.
