Insecta

Insecta, or insects, is a diverse class of small, six-legged animals within the phylum Arthropoda. They are characterized by their three main body parts: the head, thorax, and abdomen. Insects have exoskeletons, compound eyes, and most can fly. They play essential roles in ecosystems, such as pollinating plants, decomposing organic matter, and serving as food for other wildlife. With over a million described species, insects are the largest group of animals on Earth and exhibit immense variety in size, shape, and behavior, impacting everything from agriculture to human health.
