- Abstract
The northern forestfly, Lednia borealis Baumann and Kondratieff, 2010 (Plecoptera: Nemouridae), is a rare montane stonefly that until recently was thought to be endemic to Washington State. It is one of 4 described Lednia species in the western United States and Canada and the only member of its genus known to occur in Washington. All 4 Lednia species are associated with cold-water habitat in alpine and subalpine habitats; because of this, they may be especially vulnerable to threats associated with climate change. However, L. borealis is rarely targeted in species inventories or survey efforts, and more information is needed about its distribution and habitat associations in order to assess its conservation status. To address these data gaps, we conducted targeted surveys at 94 sites in montane areas of Washington State from 2015 to 2019. We collected L. borealis at only 8 of these (8.5%), bringing the total number of known sites to 19. In this paper, we update the known distribution for the species, report recent COI barcoding results, highlight a confirmed habitat association with glacial edge meltwater, and provide recommendations for future surveys.
