Brachycentrus occidentalis
humpless casemaker caddisfly
Brachycentrus occidentalis is a species of humpless casemaker caddisfly in the family Brachycentridae. It is a filter-feeding aquatic insect whose larvae construct fixed retreats with silk nets to capture food particles from flowing water. The species has been studied for its behavioral ecology during pupation, including cannibalism and predation pressures, and for its sensitivity to suspended sediments in stream environments.
