Hydropsyche occidentalis
Hydropsyche occidentalis is a filter-feeding caddisfly species in the family Hydropsychidae, found in lotic (flowing water) streams of North America. It constructs fixed capture nets to filter organic particles from the water column, playing a significant role in stream ecosystem function. The species has been studied for its bioenergetics and contribution to controlling organic transport in streams, where it can comprise a substantial portion of invertebrate biomass in suitable habitats.
