Ralph Edward Dewalt

Ralph Edward Dewalt serves as an Associate Research Scientist in Aquatic Entomology at the Illinois Natural History Survey, which is part of the University of Illinois Urbana-Champaign. His research focuses primarily on freshwater insects, with special emphasis on stoneflies (Plecoptera) and caddisflies (Trichoptera).

Dr. Dewalt's research interests span aquatic entomology, insect taxonomy, and biodiversity assessment. His work particularly emphasizes the systematics of Plecoptera (stoneflies) and Trichoptera (caddisflies), with numerous publications describing species, their distributions, and ecological requirements. His research combines morphological analysis with molecular techniques to understand evolutionary relationships among freshwater insects.

Analysis of Dewalt's recent publications reveals a strong focus on taxonomic revisions, species descriptions, and regional biodiversity assessments. His work frequently employs both traditional morphological methods and modern molecular techniques to address systematic questions. Much of his research involves compiling and analyzing museum specimen data to document regional insect faunas and track temporal changes in aquatic insect communities.

Dewalt has contributed significantly to our understanding of North American freshwater insect biodiversity through his extensive publication record of 84 research items, including 56 articles, conference contributions, technical reports, and book chapters. His work provides essential baseline data for conservation efforts and ecological monitoring of freshwater systems.
