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.
The Sikorsky R-4 is a two-seat helicopter that was designed by Igor Sikorsky with a single, three-bladed main rotor and powered by a radial engine. The R-4 was the world's first large-scale mass-produced helicopter and the first helicopter used by the United States Army Air Forces, the United States Navy, the United States Coast Guard and the United Kingdom's Royal Air Force and Royal Navy. In U.S. Navy and U.S. Coast Guard service, the helicopter was known as the Sikorsky HNS-1. In British service it was known as the Hoverfly.
Episyrphus balteatus, sometimes called the marmalade hoverfly, is a relatively small hoverfly (9–12 mm) of the Syrphidae family, widespread throughout the Palaearctic region, which covers Europe, North Asia, and North Africa. It is considered the most abundant native hoverfly in Central Europe.
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.
Syritta pipiens, sometimes called the thick-legged hoverfly, is one of the most common species in the insect family Syrphidae. This fly originates from Europe and is currently distributed across Eurasia and North America. They are fast and nimble fliers, and their larvae are found in wet, rotting organic matter such as garden compost, manure, and silage. The species is also commonly found in human-created environments such as most farmland, gardens, and urban parks, wherever there are flowers. This species is an important part of its native ecosystem as adult Syritta pipiens flies are critical pollinators for a variety of flowering plants and the species supports parasitism by various parasitic wasp species. Thus, they play an important role in environmental functionality, and can serve as bio-indicators, in which their abundance can reflect the health of the environment. Syritta pipiens looks like many predatory hoverfly species, yet is not predatory.
Eupeodes luniger is a common species of hoverfly.
Sphaerophoria scripta, the long hoverfly, is a species of hoverfly belonging to the family Syrphidae.
Baccha elongata is a species of hoverfly in the genus Baccha.
Blera fallax, the pine hoverfly or roodkapje, is a rare species of hoverfly normally associated with mature pine trees in Northern and Central Europe.
Anasimyia is a genus of wetland hoverflies with aquatic larvae. The genus was formerly regarded as a subgenus of the similar Lejops, and recently elevated to genus.
Parhelophilus is a genus of hoverflies. They are slightly smaller than flies of the genus Helophilus, and have a Holarctic distribution.
The Sikorsky R-6 is an American light two-seat helicopter of the 1940s. In Royal Air Force and Royal Navy service, it was named the Hoverfly II.
The Brachyopini is a tribe of hoverflies. Unlike many members of this family these flies are generally darker and less colourful though some genera contain species with an attractive metallic lustre e.g. Chrysogaster. Some like Brachyopa are associated with sap runs where their larvae feed on decaying sap. Others are found in boggy areas where their often semiaquatic larvae feed on decaying organic matter.
Eristalini is a tribe of hoverflies. Several species are well-known honeybee mimics, such as the drone fly Eristalis tenax, while other genera such as Helophilus and Parhelophilus exhibit wasp-like patterns of yellow and black stripes, both strategies to avoid predation by visual predators such as birds.
Pipizini is a tribe of small to medium-sized generally black hoverflies, although some species also have orange spots on their abdomen. This nondescript colouring can lead to some species being confused with other dark hoverflies from other tribes. The lack of a facial knob is a good defining feature which separates them from most of these other hoverflies. As with other species in the subfamily Syrphinae the larvae feed on aphids though there seems to be a preference for wax-secreting aphids e.g. Pemphigidae.
The Rhingiini is a tribe of hoverflies.
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.
The Spheginina is a subtribe of hoverflies.
The Brachyopina is a subtribe of hoverflies.
