Insects have dominated the terrestrial planet for more than 350 million years. While entomologists have recognized and named more than one million different species of insects, experts vary widely on the true number of insects species—with estimates ranging from 3 to 30 million unique species. At any given moment, 200+ million insects live for every human on Earth; over 70 percent of all animal species are insects. They have achieved something that has eluded humans—sustainable development. Insects are the primary consumers of plants, yet they are also the dominant pollinators, thus ensuring plant reproduction. They play a critical role in disease transmission yet the service they provide to ecological maintenance is unparalleled.
Entomologists conduct insect-based research in numerous areas ranging from general biology, natural history, systematics, ecology and behavior, to molecular biology, physiology and development, to medical and agricultural entomology. Emerging areas include invasive species, biodiversity, pollination ecology, forensics, global health, and genomics. Entomology is a very specific discipline, yet at the same time, an immensely broad and diverse field of study touching a wide array of other subjects. As such, entomological training provides many choices and opportunities for those interested in the diversity of nature. While some entomologists work in the field, others work in the laboratory or classroom.
Students majoring in entomology study in a variety of fundamental and applied fields. Graduates find employment in college and university teaching, research and extension work, state and federal government service, industry, and research institutes.
Students can complete an undergraduate major in entomology under the bachelor of science degree program.
Students interested in graduate work should consult the Graduate Guide.
To declare this major, students must be admitted to UW–Madison and the College of Agricultural and Life Sciences (CALS). For information about becoming a CALS first-year or transfer student, see Entering the College.
Students who attend Student Orientation, Advising, and Registration (SOAR) with the College of Agricultural and Life Sciences have the option to declare this major at SOAR. Students may otherwise declare after they have begun their undergraduate studies. For more information, contact the advisor listed under the Advising and Careers tab.
University General Education Requirements
All undergraduate students at the University of Wisconsin–Madison are required to fulfill a minimum set of common university general education requirements to ensure that every graduate acquires the essential core of an undergraduate education. This core establishes a foundation for living a productive life, being a citizen of the world, appreciating aesthetic values, and engaging in lifelong learning in a continually changing world. Various schools and colleges will have requirements in addition to the requirements listed below. Consult your advisor for assistance, as needed. For additional information, see the university Undergraduate General Education Requirements section of the Guide.

Undergraduate Advising in Entomology
Undergraduate students are assigned to the Entomology undergraduate faculty advisor Dr. Dan Young. However, since the vast majority of Entomology B.S. students do independent research during their undergraduate career, it is important to meet with other entomology faculty members to learn about all of the research possibilities.
Undergraduates in Entomology are strongly urged to meet with their advisor before they enroll for the upcoming term.
For more information about the Entomology B.S. or the department in general, please contact Dr. Dan Young (firstname.lastname@example.org).
For more information on careers available to Entomology students, please visit our Internship & Job Resources page. For more information on other academic, co-curricular, financial aid, and career opportunities and services available to Entomology B.S. students, please visit the CALS Career Services page. Students in the major are welcome to make an individual appointment with their advisor to discuss a number of career related topics such as career exploration, search strategies, graduate school, and review of application materials (resume, CV, letters, etc.).

While entomology clearly is “big science,” our department prides itself on a “small campus” feel in which we get to know our undergraduate students during their time with us.
In the classroom, we strive to maintain labs at not more than 15-20 students to maximize individualized and participatory learning. Students are given additional opportunities for deep and engaged learning experiences through honors options that are generally available for most courses and field and/or lab experiences in many of the upper-level courses.
Very nearly all our majors have opportunities to work alongside our faculty and graduate students in research labs and in the field. Our major accommodates 1–3 credits (of the 15 entomology credits required to major) in the area of directed/independent study and internships to promote extracurricular and outside the traditional classroom learning.
Many of our undergraduate majors are also involved in service learning and teaching through our departmental “Insect Ambassadors” outreach program to K–12, various clubs, and organizations. We are committed to the UW System goal to provide Wisconsin’s citizens with opportunities to benefit from, and contribute to, the state’s growing “knowledge economy” through the land-grant university three-fold mission of teaching, research, and public service. We also have an active Undergraduate Entomology Society for majors—or any UW–Madison students interested in entomology. Research and internship opportunities are also available in the UW Insect Research Collection (WIRC) as well as possible participation in WIRC sponsored collecting expeditions in Wisconsin and around the United States.
