The Great Lakes Entomologist
The caddisfly assemblages of Finch Creek, a small woodland stream in northern Lower Michigan, was sampled along its entire continuum during May, June, July, and September 2021–2022 using ultraviolet blacklight traps. A total of 98 species representing 15 families and 49 genera were collected, including two species [Lepidostoma prominens (Banks) and L. sommermanae (Ross)] not previously reported from Michigan, and several others either not previously found in the Lower Peninsula or not reported from the state for >70 years. A non-metric multidimensional scaling ordination determined distinct species assemblages corresponding to the spring, summer, and fall months. Shredders dominated the …

The Caddisflies (Trichoptera) Of Drummond Island, Michigan, With An Assessment Of Lake Assemblage Biomass, David Houghton, Robert Haack
The Great Lakes Entomologist
The adult caddisfly assemblages of Drummond Island, a Michigan island in Lake Huron near the Canadian border, were sampled in 2021–2022 from 3 sites on Lake Huron, 8 inland lakes, 2 vernal pools, and 1 stream. Adult caddisflies from each site were sampled in spring, summer, and autumn using ultraviolet blacklight traps. A total of 89 species representing 37 genera and 12 families was collected, including several not seen in Michigan for 50–70 years and the first confirmation of the rare species Beothukus complicatus (Banks) (Phryganeidae) from the state. A non-metric multidimensional scaling ordination determined distinct species assemblages between lakes, …
