The Class Insecta comprises the largest group of animals on Earth, with over a million described species. Insects are arthropods with three main body segments (head, thorax, abdomen), three pairs of legs, compound eyes, and usually one or two pairs of wings. They exhibit diverse feeding habits, life cycles (often with metamorphosis), and behaviors, occupying nearly every habitat. Insects play crucial ecological roles as pollinators, decomposers, and food sources for other animals, and they significantly impact agriculture, human health, and ecosystems worldwide.
