Hydropsyche sparna
Ross, 1938
Hydropsyche sparna is a of net-spinning caddisfly in the Hydropsychidae. It has been studied primarily for its behavioral responses to suspended particles and deposited bedload sediment in flowing water environments. The species is currently treated as a synonym of Ceratopsyche sparna in some taxonomic databases. Research on this species has contributed to understanding how filter-feeding aquatic insects modify their foraging in response to changing environmental conditions.

Habitat
Flowing water environments (lotic systems) with suspended particles and bedload sediment. Constructed capture nets are positioned in current to filter food particles from the water column.
Distribution
North America; recorded from Vermont, United States.
Diet
Filter-feeding on suspended particles captured using silk nets.
Behavior
Net-tending are modified in response to suspended particle concentrations. Individuals exhibit behavioral plasticity when responding to deposited bedload sediment, adjusting their activities to accommodate changing substrate conditions.
Ecological Role
Filter-feeder contributing to particle processing and organic matter transfer in aquatic .
