What is the term used for a person who studies insects?

The term used for a person who studies insects is "entomologist." This specialism falls under the broader field of entomology, which is the scientific study of insects, their behavior, ecology, physiology, and taxonomy. Entomologists play a crucial role in various sectors, including agriculture, ecology, and public health, as they study the impact of insects on crops, ecosystems, and human health.

The other terms refer to different fields of study: an ornithologist studies birds, a botanist focuses on plants, and a cartographer specializes in mapping and geography. Each of these professions has a distinct area of expertise, differentiating them from entomology and the study of insects.
