• Brachycentrus

  Grannom Caddisflies, Humpless Casemaker Caddisflies

  Brachycentrus is a genus of caddisflies in the family Brachycentridae, commonly known as grannoms or humpless casemaker caddisflies. The genus contains at least 30 described species distributed across North America and Eurasia. Larvae are aquatic filter-feeders that construct portable cases from silk and environmental materials such as sand, small stones, or plant fragments. The genus is ecologically significant as an important prey item for trout and other freshwater fish.

• 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.
