I am an entomologist with special interests in prairie ecology and insect behavior, and have been teaching in the Department of Biology at Luther since 1993. Along with keeping up with my family (my lovely wife, 3 kids plus a son-in-law and daughter-in-law, and our dog), I have a variety of other interests.
One interest involves understanding the interactions between science and the Christian faith, especially the area of creation care, looking at our relationship to the environment and our responsibilities as stewards of creation. I am a member of Decorah Covenant Church.
I enjoy gardening, playing trombone, hiking, cross-country skiing, swimming and snorkeling, fly fishing, burning prairies, and eating ice cream.
In the summer I often teach in the Black Hills of South Dakota at the Wheaton College Science Station. I’ve taught Ecology, Entomology, Field Zoology, and I currently teach the zoology portion of their Diversity of Life course.
BIO 251: Entomology
An introduction to the biology and diversity of insects, particularly the life histories, form and function, ecology, and behavior of various insect groups found in various habitats.
BIO 151: Principles of Biology: Ecology, Evolution and Biodiversity
The first class in a two-course introduction to fundamental biological principles as exhibited by microbes, plants, and animals. Designed as an introduction to the biology major; required for the biology major and minor.
BIO 112: Insects, Humans and the Environment
A study of relationships among insects, humans, and the environment. Using insects as a model, biological concepts such as evolution, form and function, genetics, development, natural history, biodiversity, and conservation will be covered. Includes a presentation of why insects are so successful, giving attention to their behavior and ecological roles in nature, impacts on human society as causes of famines, plagues and epidemics, and importance in human cultures. Laboratory includes field trips and an investigative approach to learning insect biology.
BIO 247: Marine Biology (J-term Study Away)
Based at the Roatan Institute of Marine Sciences (Honduras), this course is an introduction to the ecology and taxonomy of marine and terrestrial invertebrates, fish, birds, and common plants of the northern West Indies. In addition to professor-led field excursions including extensive SCUBA diving and snorkeling on coral reefs, students develop and complete independent research projects. Several days will be spent on the Luther campus for pre-trip orientation and post-trip completion of projects.

Dr. Larsen leads the entomology research laboratory at Luther College. The mission of the entomology research laboratory at Luther College is to provide students meaningful research experiences in insect ecology and opportunities to explore entomology as a subdiscipline of biology, while contributing to our knowledge of and the conservation of insect diversity in northeast Iowa.
The laboratory’s overall research question is: How does habitat and habitat management affect insect biodiversity in northeast Iowa native ecosystems? It has two goals:
1. To document insect diversity in northeast Iowa through surveys of selected taxa in native habitats and maintaining a research insect collection.
2. To communicate our research findings with the broader entomological and scientific community through presentations at scientific meetings, publications in primary research journals, and reports to conservation agencies.
