Hydropsychinae is a of caddisflies (Trichoptera) within the Hydropsychidae, commonly known as net-spinning caddisflies. Larvae construct fixed capture nets in flowing water to filter food particles. The subfamily is taxonomically diverse, with generic revisions documented in multiple regions including New Zealand and the Americas.

Identification
males are identified primarily by genitalic structures, which form the basis of taxonomic keys. Larvae are distinguished by net architecture, body setation, and capsule . In New Zealand, the Orthopsyche and Aoteapsyche were separated from Hydropsyche based on combined adult and larval characters.

Habitat
Flowing water environments including streams and rivers where larvae attach their nets to stable substrates.
Distribution
Worldwide distribution with documented occurrence in Mexico, Central America, New Zealand, and other regions. The Hydropsyche has a broad global distribution.
Behavior
Larvae are filter-feeders that construct fixed silken nets to capture drifting food particles in currents.
Ecological Role
Larvae function as filter-feeders in lotic , processing suspended organic matter and contributing to nutrient cycling in freshwater .

Taxonomic History
Generic boundaries within Hydropsychinae have been revised multiple times. In New Zealand, eight formerly placed in Hydropsyche were reassigned to two new , Orthopsyche and Aoteapsyche, based on morphological analysis.
Research Focus
Published research on Hydropsychinae has emphasized alpha and description rather than ; detailed biological data for many remain unstudied.
