Hoverflies, also called flower flies or syrphids, make up the insect family Syrphidae. As their common name suggests, 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.
Eristalinae are one of the four subfamilies of the fly family Syrphidae, or hoverflies. A well-known species included in this subfamily is the dronefly, Eristalis tenax.
Sericomyia transversa , the Yellow-spotted Pond Fly , is an uncommon species of syrphid fly observed in northeastern North America.. Hoverflies can remain nearly motionless in flight. The adults are also known as flower flies for they are commonly found on flowers, from which they get both energy-giving nectar and protein-rich pollen. The larvae of this genus are known as rat tailed maggots for the long posterior breathing tube.
Spilomyia crandalli, Crandall's Hornet Fly, is a rare species of syrphid fly first officially described by Curran in 1951. This species is found in western North America near the Pacific coast.
