Habitat

Lotic (running water) environments including streams and rivers; laboratory studies indicate preference for substrates with pebbles suitable for case construction and attachment.

Distribution

North America; specifically recorded from the Nearctic region.

Diet

are suspension-feeders, capturing particles and small in constructed in flowing water.

Life Cycle

with , larval, pupal, and stages. are aquatic and construct portable cases; specific developmental duration not documented.

Behavior

display -dependent spacing : aggregated distributions at low densities, uniform spacing at high densities due to aggressive encounters and . When suitable substrate is available, larvae aggregate regardless of density; excess individuals are forced into peripheral areas when refuge reaches capacity.

Ecological Role

function as suspension-feeders in aquatic , capturing fine particulate matter and transferring energy to higher . Their -spinning activity may influence local hydrodynamics and particle deposition in streams.
