Stream Ecology - The Other Players
True Flies (Diptera)
Midges (Chironomidae): mostly collector-gatherers. A very diverse group found in most aquatic habitats.
Filter-collectors. Larval blackflies have fans that they extend into the stream current. These fans can filter out particles as fine bacteria.
Crane Flies (Tipulidae)
Large shredders of leaf litter.
Flatworms (Turbellaria): Predators and collector-gatherers. They are sometime found on dead salmon.
Water Mites (Hydracarina): These are predators or parasites depending on life stage.
Aquatic Earthworms (Oligochaeta): Collector-gatherers.
