Insecta (class)

Insecta is a class of animals within the phylum Arthropoda, characterized by six legs, a segmented body divided into head, thorax, and abdomen, and usually possessing wings. They are the most diverse group of animals on Earth, including species like beetles, butterflies, ants, and flies. Insects have an exoskeleton for protection, undergo metamorphosis during their life cycle, and play vital roles in ecosystems—pollinating plants, recycling nutrients, and serving as food for many other animals. Their adaptations and vast diversity make insects fundamental to life on Earth.
