 Gersich,FM and Brusven,MA 1982 Volcanic ash accumulation and ash-voiding mechanisms of aquatic insects. Journal of the Kansas Entomological Society, 55(2) 290-296. Abstract: "Four species of aquatic insects (Hesperoperla pacifica, Rhyacophila acropedes/R. vao, Drunella doddsi and Rhithrogena robusta) were subjected to suspended ash concentration of ca. 2000 mg/1 in laboratory streams for 48 hr. Macro- and microscopic examination revealed substantial ash accumulation on the exo-skeleton; however, acute toxicity was not noted. Ash-impacted aquatic insects placed in a clean water environment voided appreciable amounts of ash within 24 hr. We conclude that the four species studied had high short-term exposure tolerances to ash and that behavioral attributes allowed for the removal of exoskeletal ash deposits once the perturbation ceased."

Rader RB and Ward JV. 1988 Influence of regulation on environmental conditions and the macroinvertebrate community in the upper Colorado River. Regulated Rivers: Research and Management 2:597-618. Quote from page 611: "The reference site was represented by twelve species of caddisflies, including relatively abundant populations of Arctopsyche grandis and Rhyacophila acropedes. Trichopterans at the regulated site, however, were represented by nine rare and three slightly more abundant caddisflies (Hydroptila sp., Brachycentrus americanus, and Hesperophylax designatus). The abundance of net-spinning caddisflies was significantly reduced in the regulated site compared to both reference and recovery locations (p=0.05), as has been reported by several workers (Armitage and Capper, 1976; Müller, 1962; Ward, 1987).

Has a key to larvae that includes R. acropedes, which we now know as R. brunnea. However the author could not distinguish R. acropedes from the larvae of R. vao.
