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, preying 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.
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. Hoverflies get their names from the ability to remain nearly motionless while in flight. The adults are also known as flower flies for they are commonly found around and on flowers, from which they get both energy-giving nectar and protein-rich pollen. The larvae are known as the short-tailed larvae, suited for moist areas such as rot holes of trees.
Spilomyia liturata, the Rocky Mountain Hornet Fly, is an uncommon species of syrphid fly. This species is found in western North America along the Rocky Mountains. Hoverflies get their names from the ability to remain nearly motionless while in flight. The adults are also known as flower flies for they are commonly found around and on flowers, from which they get both energy-giving nectar and protein-rich pollen. The larvae are known as the short-tailed larvae, suited for moist areas such as rot holes of trees.

Platycheirus modestus , also known as the yellow sedgesitter, is an uncommon species of syrphid fly observed throughout Northern North America. Hoverflies can remain nearly motionless in flight. The adults are also known as flower flies for they are usually found on flowers from which they get both energy-giving nectar and protein-rich pollen. Larvae are aphid predators.
Platycheirus nearcticus, the Nearctic broadhand sedgesitter, is a common species of syrphid fly observed in mainly in northeastern North America but scattered more broadly across the continent. 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. Larvae are aphid predators.
Platycheirus thompsoni, or Thompson's sedgesitter, 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. Larvae are aphid predators.
Cheilosia latrans, the steely blacklet, is a very common species of syrphid fly observed in northern 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 nutrient-rich nectar and pollen. Larvae when known are plant feeders.
