Hoverfly Totally Explained

Everything about Syrphid Fly totally explained

For the helicopter see: Sikorsky R-4 Flies in the Diptera family Syrphidae are commonly known as hoverflies, flower flies, or Syrphid flies.
   As their common names suggest, they're often seen hovering or nectaring at flowers; the adults of many species feed mainly on nectar and pollen, while the larvae (maggots) eat a wide range of foods. In some species, the larvae are saprotrophs, eating decaying plant and animal matter in the soil or in ponds and streams. In other species, the larvae are insectivores and prey on aphids, thrips, and other plant-sucking insects.
   Aphids alone cause tens of millions of dollars of damage to crops worldwide every year, and so aphid-feeding hover-flies are being recognized as important natural enemies of pests, and potential agents for use in biological control. Some adult syrphid flies are important pollinators.
   About 6,000 species in 200 genera have been described. Hoverflies are common throughout the world and can be found on every continent except Antarctica.
Hoverflies and gardening
Many species of Hoverfly larvae prey upon pest insects, including the leafhoppers which spread some diseases like curly top, and aphids. Therefore they're seen in biocontrol as a natural means of reducing the levels of pests.
   Gardeners, therefore, will sometimes use companion plants to attract hoverflies. Those reputed to do so include alyssum, Iberis umbellata, statice, buckwheat, chamomile, parsley, and yarrow.
