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.

Las moscas Helophilus son un género diverso de moscas de tamaño moderado a grande de la familia Syrphidae. Mimetizan a las abejas. Las larvas se alimentan filtrando partículas de aguas ricas en materia orgánica.
