Syrphid fly

Description:

Also called flower flies, they are 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.Hoverflies are harmless to most other animals despite their mimicry of more dangerous wasps and bees, which serves to ward off predators,

Habitat:

A species of flower fly found from eastern Canada south to Texas.
