Hydropsyche betteni
Common Netspinner
Hydropsyche betteni is a species of netspinning caddisfly in the family Hydropsychidae, described by Ross in 1938. It is one of the most widespread and commonly encountered members of its genus in North America. Like other hydropsychids, the larvae construct fixed capture nets to filter food from flowing water. The species is well-documented in freshwater biomonitoring studies due to its abundance and sensitivity to water quality.
