The scientific study of insects is known as entomology. It is a branch of zoology that focuses on the classification, behavior, ecology, and conservation of insects, which comprise the largest group of animals on Earth. Entomologists study various aspects of insects, including their anatomy, life cycles, interactions with ecosystems, and their roles as pollinators or pests. This field of study is crucial for agriculture, biodiversity, and understanding ecological systems, as insects can significantly influence plant growth and animal populations, as well as provide insight into environmental health.
