Hover flies, also called flower flies or syrphid flies, 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.
Callicera erratica , the Golden Pine Fly , is a rare species of syrphid fly observed in the Northeastern United States and Canada. Hoverflies can remain nearly motionless in flight.

Larvae live in water filled rotholes and cavities of old living conifers.

Spilomyia alcimus, the Broad-banded Hornet Fly, is an uncommon species of syrphid fly first officially described by Walker in 1849. 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.
Brachypalpus oarus, the Eastern Catkin, is a common species of syrphid fly first officially described by Walker in 1849. 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 of the rat-tailed type feeding on decaying sap under tree bark.
Temnostoma balyras , the Yellow-haired Falsehorn , is a common species of syrphid fly observed in the eastern half of the United States and adjacent areas of Canada. 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 burrow in moist decayed wood using their hooks as rasping organs operated in a forwards and backwards motion by huge muscles housed in the mesothorax and metathorax. The larvae of T.balyras have been described by Heiss in "A classification of the larvae and puparia of the Syrphidae of Illinois exclusive of aquatic forms".
Chalcosyrphus (Xylotomima) libo, the Long-haired Leafwalker, is an uncommon species of syrphid fly observed in north-central North America. Hoverflies are able to remain nearly motionless 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.
Chalcosyrphus (Xylotomima) piger, the short-haired leafwalker, is an uncommon species of syrphid fly found throughout North America and Europe. 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. Larvae have been identified from sappy hollows from Larix and Pinus.
Blera notata , the Ornate Wood Fly, is a rare species of syrphid fly first officially described by Weidemann in 1830. Hoverflies get their names from the ability to remain nearly motionless while in flight. The adults, 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 of the rat-tailed type, feeding on exuding sap or in the rot holes of trees.
Chalcosyrphus (Xylotomima) chalybeus , the Violet Leafwalker, is a fairly common species of syrphid fly observed in the Northeastern United States. 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.
