  Basis for Former Listing

Two female caddisflies identified as Setodes guttatus were reported from Cass County in 1965 (Etnier 1965). This collection is the only known occurence of this species in Minnesota. Setodes guttatus was listed as a special concern species in 1996.

  Basis for Delisting

Upon examination, comparison with other specimens, and using Holzenthal (1982) and Holzenthal and Harris (1985) as guides, specimens of this species have been re-identified as S. oligius (Ross). The latter species is known in Minnesota from scattered localities in the central and northcentral portions of the state (Houghton et al. 2001). Setodes guttatus is known only from New England, Quebec, and Alabama and it is unlikely to occur in Minnesota. The species was delisted in 2013.
