Cheumatopsyche ela

Denning, 1942

Cheumatopsyche ela is a of net-spinning caddisfly in the Hydropsychidae, first described by Denning in 1942. The species occurs in North America and is part of a known for constructing silk capture nets in flowing water . Larvae exhibit -dependent patterns in laboratory settings, with aggressive and observed at high densities. As with other hydropsychids, are short-lived and primarily focused on .

Habitat

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

Distribution

North America; specifically recorded from the Nearctic region.

Diet

Larvae are suspension-feeders, capturing organic particles and small in silk nets constructed in flowing water.

Life Cycle

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

Behavior

Larvae 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

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