Southern Appalachian Mayflies, Stoneflies, and Caddisflies: Session 2

4 Credit Hours
July 6-18, 2026
Instructors: Session 1: Dr. John Morse, Clemson University & Dr. Alexander Orfinger, Dalton State College. Session 2: Dr. John Morse, Clemson University & Dr. Kelly Murray-Stoker, Emory University
This immersive, two-week course provides a comprehensive introduction to the natural history, evolution, and taxonomy of the three major aquatic insect orders used in freshwater bioassessment: mayflies (Ephemeroptera), stoneflies (Plecoptera), and caddisflies (Trichoptera). Through a combination of several field excursions to Appalachian mountain streams and focused laboratory identification sessions, students will develop the skills needed to recognize EPT larvae—typically to at least genus—and adults to family level.
Course topics include systematics, morphology, behavioral and physiological adaptations for freshwater life, and the ecological roles of EPT taxa in stream ecosystems. Fieldwork emphasizes diverse collecting techniques across multiple stream orders, while laboratory sessions provide structured practice with diagnostic characters and curated identification resources. Throughout the course, students engage with the principles that make EPT taxa foundational to ecological monitoring, water-quality assessment, and aquatic biodiversity research.
Ideal for students in ecology, entomology, environmental science, or freshwater biology, this course offers the rare opportunity to build taxonomic expertise through intensive hands-on training in one of the most biodiverse regions of the Southern Appalachians.
