Subfamily Eristalinae
~500 spp. in 73 genera in our area(1)
humeri pilose
larvae in moist, sometimes shallow aquatic environments
This subfamily has the widest range of larval habitats. Most Eristalinae larvae are saprophagous. They live in sap trails, under bark, in rot-holes in trees and in decaying organic material such as dung and compost. Some live as scavengers on the remains of insects and other material. Others are leaf miners, tunnel in stems and root. Some are specialize on wax-secreting aphids. Some are parasitoids in wasp or bees nests.
larvae of most feed on decaying organic debris. They are filter feeders in different kinds of aquatic media. They purify water by filtering microorganisms and other products. Some feed on bulbs and are considered garden pests.
