Hydropsyche californica
Hydropsyche californica is a species of net-spinning caddisfly (Trichoptera: Hydropsychidae) described by Banks in 1899. It inhabits freshwater benthic environments and has been extensively studied as a bioindicator for metal contamination in aquatic ecosystems, particularly in relation to mine drainage. Research has demonstrated its utility for monitoring cadmium, copper, lead, and zinc exposure in rivers.
