Entomology is the field that studies insects. It covers insect anatomy, life cycles, behavior, and classification, and it also looks at how insects interact with ecosystems, including their roles as pollinators, pests, or disease vectors. This focus on insects specifically is why it’s the best answer when the question asks which field studies insects. Ichthyology studies fish, archaeology explores past human societies through artifacts, and ecology is the broader study of how organisms interact with each other and their environment—encompassing many species, not just insects.
