Updated checklist, habitat affinities, and changes over time of the Indiana (USA) caddisfly fauna (Insecta, Trichoptera).

Based on recent collecting and a synthesis of ~100 years of historical data, 219 caddisfly species are reported from the state of Indiana. Seventeen species are reported herein from the state for the first time, including two previously thought to be endemic to the southeastern USA. Species records are also presented herein organized by drainage basin, ecoregion, glacial history, and waterbody type for two distinct time periods: before 1983 and after 2005.

Comparison of caddisfly (Insecta, Trichoptera) assemblages from lake and river habitats of the Huron Mountains of Michigan (USA).

The caddisfly assemblages of six lakes and 12 1-4 order streams of the Huron Mountains of northern Upper Michigan (USA) were sampled monthly with ultraviolet lights during June-September 2019. A total of 169 species representing 63 genera and 19 families was collected, including five species not found elsewhere in Michigan and two species endemic to the state. Species assemblages between lotic and lentic habitats were distinct from each other, with 11 species indicating lakes and 23 indicating rivers.

Ash-free dry mass values for northcentral USA caddisflies (Insecta, Trichoptera).

Ash-free dry mass (AFDM) values are presented for the adult stage of 63 caddisfly species commonly found throughout the northcentral US. Weights ranged from 0.01 mg for the smallest species to 7.
