An entomologist is a scientist who studies insects and their relationships with other organisms and the environment. They are experts in the field of entomology, which is the study of insects. Entomologists may specialize in a particular type of insect, such as ants, bees, or beetles, or they may study arthropods, a related group of species that includes spiders and scorpions. Some entomologists study how insects behave, while others study where they live. Entomologists may also look at insect pests and the diseases they carry, or they may describe new insect species that are discovered. There are even entomologists that help solve crimes by studying dead bodies and the insects that live on them.

Most entomologists have at least a bachelors degree, and many go on to earn a masters and/or doctoral degree. They may work in a variety of settings, including colleges and universities, governmental agencies, agriculture organizations, food processing, pest control, health services, and more. Entomology is crucial to our understanding of human disease, agriculture, evolution, ecology, and biodiversity.
