Bugguide notes 22 species within this genus in North America. The larvae are filter feeders and spin very fine-meshed nets, usually grouped together on the undersides of rocks near the upstream edge, to capture small particles of plant and animal matter plus algae such as diatoms.
There are 12 records in the project database.
