Data for laboratory experiments conducted with the caddisflies Hydropsyche californica and Arctopsyche grandis to derive copper and cadmium bioaccumulation parameters

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2023-05-19T00:00:00Z
This USGS data release includes data from experiments conducted with two species of caddisflies (Hydropsyche californica and Arctopsyche grandis (Order: Trichoptera) to quantify copper and cadmium uptake and loss after dissolved and dietary exposures. Both Arctopsyche and Hydropsyche belong to the family Hydropsychidae (O: Trichoptera). They are relatively sessile, net-spinning filter feeders. Data from these experiments can be used to characterize physiological parameters used in a bioaccumulation dynamic model.
