The study of insects is known as entomology. This branch of zoology focuses on the classification, behavior, ecology, and physiology of insects, which are the most diverse group of organisms on Earth. Entomologists study various aspects of insects, including their roles in ecosystems, pest management, and their importance in pollination, agriculture, and as bioindicators of environmental health. Insects like bees, butterflies, and beetles are crucial for biodiversity, making entomological research vital for understanding and preserving ecological balance and addressing challenges like climate change and habitat loss.
