Description: Most adult aquatic insects that emerge from streams live briefly in the nearby riparian zone. Adult activities, such as mating, dispersal, and feeding, influence their distribution in the terrestrial habitat. A study at Big Sulphur Creek, California, has shown that both numbers and biomass of adult aquatic insects are greatest in the near-stream vegetation; however, adults can be relatively common 150 meters or more from the stream. Because adult aquatic insects are abundant, they represent a primary food resource for many riparian insectivores. The role of adult aquatic insects in the riparian zone must be better understood for riparian management plans to be complete.
