Syrphid fly

Hover flies, also called flower flies or syrphids, make up the insect family Syrphidae. As their common name suggests, they are often seen hovering, maintaining a spot in the air as part of their display behavior; 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, specifically detritivores, eating decaying plant and animal matter in the soil or in ponds and streams.
