In this paper 284 caddisfly (Trichoptera) species representing 20 families and 74 genera are reported from Minnesota based on examination of over 100,000 larval and adult specimens. Of these, 28 are new state species records and 87 are new additions to the fauna since Etnier's (1965) state checklist. The known distributions of all species from five geographic regions of Minnesota are reported. Also, the caddisfly faunas of these five regions are compared, the abundance of each species based on material examined stated, and protective status of rare species noted. An additional 21 species recorded in the literature from Minnesota are listed as doubtful.
