Larvae: see (10)(11); larvae of many holarctic genera shown/keyed in (12)Habitat Many adults frequent flowers; some larvae live in ant nests, and a few are associated with wasps. Food Larvae may feed on decaying vegetation, aquatic detritus, wet wood, bulbs of forbs of living plants, but most are predators; Many species of Allograpta, Baccha, Mesograpta, Melanostoma, Paragus, Pipiza, Scaeva, Syrphus, Metasyrphus, and Sphaerophoria are important aphid predators; larvae of Baccha, Pipiza, Scaeva, Syrphus, and Metasyrphus feed on coccids. ( Weems 1954). Adults often feed on nectar and/or pollen Remarks Role as aphid control agents: see (13) • Role as pollinators: see (14)
Larvae that live in water with much decaying organic matter have a long anal breathing tube, and are called "rat-tailed maggots"
