Insect Biodiversity and Evolution

NOTE: This course is now administered and updated through Canvas. The files and links below are not current.

This course, offered every fall, is designed to teach students about insect taxonomy, evolutionary relationships, collection and preservation techniques, morphology, and natural history. We focus mostly on adult forms and emphasize insects found in Pennsylvania. In the lab, students will learn how to handle specimens, use diagnostic keys, and identify insects by sight. Collection techniques will be honed during field trips. The primary instructor is Dr. Andrew R. Deans; questions about the course should be sent to adeans@psu.edu. The syllabus, collection exercise, and other useful documents are available:
