This website and the North American Stonefly Project is the work of many volunteers. The leaders of the group are:

Lauren Culler

Lauren Culler is a PhD student in Ecology and Evolutionary Biology at Dartmouth College in New Hampshire. She is also a fellow in the National Science Foundation’s Integrative Graduate Education and Research Traineeship program in Polar Environmental Change. Lauren is studying the mechanisms by which environmental change affects aquatic insects in Arctic and alpine regions.

Her research endeavors have taken her to the Rocky Mountains of Colorado and to Kangerlussuaq, Greenland.

Lauren hasn’t always lived and worked in cold places. She grew up in Maryland and completed a B.S. in Biology (2005) and a M.S. in Entomology (2008) at the University of Maryland. She has taken and taught several courses in general and aquatic entomology and is happiest when collecting or looking at insects under a microscope.

She is an active student member of the Entomological Society of America and the North American Benthological Society, and recently become involved with the Federation of Fly Fishers. In 2009, she won their scholarship for her work in aquatic entomology and will be teaching a workshop in the classroom and on the river on stoneflies.

In her free time, Lauren enjoys hiking around New Hampshire and Vermont, traveling anywhere and everywhere, and learning how to ski. She can be contacted at Lauren.E.Culler{at}


David Nelson

David Nelson is a hand surgeon in San Francisco whose specialties are distal radius fractures, wrist kinematics, and post-operative pain management. He has had a life-long interest in insects, and his nickname in college was "Bugs".  While insects have never been part of his academic career, he has been involved with them recreationally for his entire life. He taught nature studies in the Sierras at the San Jose Family Camp and now is the nature director for the Cazadero Performing Arts Camp.  He has taught fly tying at the national meeting of the Federation of Fly Fishers annually since 1989 and currently serves as the Chairman of the Board of Governors for the Fly Tying Group of the Federation of Fly Fishers, a non-profit organization that is the premier fly fishing and fly tying educational organization in the world. He has produced and edited three books on fly patterns, the Patterns of the Masters, and donated all the proceeds to the Federation of Fly Fishers. His favorite bug is the stonefly and he is a member of Perla, the professional organization for entomologists who study stoneflies. He has taught classroom workshops and streamside classes on stoneflies at several national meetings of the Federation of Fly Fishers. He is working on this website to make the scientific knowledge of the professional plecopterists accessible to the fly fisherman and to bring the knowledge of fly fishing guides and the graphic power of the Internet to scientists working on stonefly identification and water quality assessment. He can be contacted at nelsondl {at}

Senior Advisors

Bill Stark, PhD, Sadler Professor of Biology, Mississippi College, is a world-renowned scientist who has published almost 200 scientific articles on stoneflies. He is the co-author, with Ken Stewart, PhD, of Nymphs of North American Stonefly Genera, the definitive text on stonefly nymphs. He is the editor of Illiesia, the International Journal of Stonefly Research. (Note: you cannot view Illiesia with Firefox, but need to use Internet Explorer).
