Trichoptera caddisflies Great Falls Turkey Run


A 3-year effort to collect and identify caddisflies (Trichoptera) along 2 sections of the Potomac River was undertaken at the request of the National Park Service. A variety of techniques including Malaise traps, light traps, and hand netting resulted in the collection of 105 species belonging to 17 families and 38 genera. Fifty-seven species or 54% were deemed rare, 20 species or 19% were common and 28 species or 27% were abundant.  Comments are made on 7 species of special interest. An addendum lists 6 additional species collected during the 4th year’s survey.
