Korte beschrijving
Determinatiesleutels | Morfologie | Morfometrie
Adults inhabit rocky riffles, runs, and flowing pools of clear creeks and small rivers. Rarely found in springs and along wave-swept margins of large impoundments (Ref. 5723, 10294). They feed on aquatic insect immatures (midges, mayflies, caddisflies) and small crustacea (isopods, amphipods, copepods) (Ref. 10294).
