Abstract
Based on a synthesis of the literature and museum records, as well as our own ultraviolet backlight sampling during 2022-2024, we list 112 caddisfly species from Nebraska, including 61 species, 11 genera, and 4 families reported from the state for the first time. Indicative of a disturbed agricultural environment, the fauna was dominated by Hydropsychidae, Hydroptilidae, and Leptoceridae, with these 3 families accounting for 68% of species richness, 88% of species occurrence records, and 98% of total specimens collected. Previously reported species that we were not able to collect in our 2022-2024 blacklight sampling were mostly in the families Limnephilidae and Phryganeidae. Species rarefaction predicted that at least another 15-50 species remain to be found in Nebraska, probably within the less disturbed central and western portions of the state.
