NAVIGATING TAXONOMIC BOUNDARIES: ADULTS OF THE NORTH AMERICAN TRICHOPTERA GENERA

In number of species, Trichoptera constitute the 7th largest order of insects and are commonly among the most abundant animals in freshwater ecosystems. Despite the importance of caddisfly adults for fly fishing, for life history research, and potentially for biomonitoring, there are no comprehensive resources for identification of the 154 North American genera in this life stage. Diagnostic keys for genera of adult Ephemeroptera, Odonata, aquatic Orthoptera, Plecoptera, aquatic Hemiptera, Megaloptera, aquatic Neuroptera, aquatic Lepidoptera, aquatic Coleoptera, Tipulidae, Culicidae, and Simuliidae were provided in the 4th edition of the reference book by Merritt et al. (2008). In the upcoming 5th edition of that work, Trichoptera will be treated in a single chapter (two chapters in most previous editions) and an illustrated key for adults of North American genera will be included. Diagnostic characters for genera will be found mainly in wing venation, tibial spurs, ocelli, maxillary palps, and other non-genitalic features. We hope that an improved ability to identify adult caddisflies will help North American freshwater scientists navigate these additional taxonomic boundaries in Trichoptera and stimulate increased research interest and practical value for this major order of freshwater insects.
