<span class="mw-page-title-main">Hover fly</span> Family of insects

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.

<span class="mw-page-title-main">Microdontinae</span> Subfamily of flies

The subfamily Microdontinae contains slightly more than 400 species of hoverflies and, while diverse, these species share several characteristics by which they differ from other syrphids. The Microdontinae are myrmecophiles, meaning they live in the nests of ants. Larval Microdontinae are scavengers or predators in ant nests, and, in contrast to other syrphid larvae, have no readily apparent body segmentation. Some species also do not exhibit the typical adult flower-visiting behaviour of other hoverflies, but instead remain near their larval host colonies.

<i>Syritta</i> Genus of hoverflies

Syritta is a genus of hoverflies, family Syrphidae.

<span class="mw-page-title-main">Eristalinae</span> Subfamily of flies

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.

<i>Xylota</i> Genus of flies

Xylota is a Holarctic genus of hoverflies similar in structure to the related genera Chalcosyrphus and Brachypalpoides. As the larvae are saprophytic they're usually found in rotting wood. The adult flies are generally associated with woodland and woodland edges and can often be seen running over the upper sides of leaves. Unlike other syrphids the adults of many species rarely visit flowers preferring instead to gather pollen from leaf surfaces. There are over 100 described species of which 12 can be found in Europe. Seven species have been recorded in Britain. Identification of species has been difficult and identifiction by photographs is risky.

<i>Spilomyia</i> Genus of flies

Spilomyia is a genus of hoverflies. Many species in the genus show Batesian mimicry of wasp models, including black and yellow patterns and modified antenna shape.

<i>Platycheirus</i> Genus of flies

Platycheirus is a large genus of hoverflies. They are also called sedgesitters.

<i>Blera</i> (fly) Genus of flies

Blera is primarily a North American genus, though there are 3 species from Europe. The genus is characterized by the following characters:

<i>Chalcosyrphus</i> Genus of flies

Chalcosyrphus is a genus of hoverflies in the subfamily Eristalinae. Many species exhibit some degree of mimicry of various sawflies and other hymenopterans and are often brightly coloured or metallic in hue. The adults are similar in structure and behavior to the related genus Xylota but differ in larval morphology. They can be found throughout Europe, Asia, and North America and seem to prefer damper, boggy habitats. The larvae are saproxylic feeders in rotten wood in these habitats.

<i>Sphegina</i> Genus of flies

Sphegina is a genus of small, slender hoverflies. They are widespread throughout Eurasia and North America. In flight they seem to have long hind legs which they often carry hanging down, making them resemble sphecid or ichneumonid wasps. Adult Sphegina are usually found in damp and shady habitats close to water in forested areas, and several species can often be found together. They often feed on white and yellow flowers of Apiaceae, Ranunculaceae, Asteraceae, and Rosaceae like Crataegus, Sorbus, and Sorbaria. Larvae nest in the sap of living and dead trees or in decaying cambium under tree bark lying in water or other damp conditions. The larvae of some species have been discovered in the tunnels of other xylophagous insects.

<i>Brachyopa</i> Genus of flies

Brachyopa is a Holarctic genus of hoverflies whose grey and brown colouration is unusual for this family and these flies can easily be overlooked amongst members of other fly families. The larvae can be found under the bark of dead branches and trees in decaying sap.

<i>Solariella segersi</i> Species of gastropod

Solariella segersi is a species of sea snail, a marine gastropod mollusk in the family Solariellidae.

Austroascia is a genus of hoverflies.

<span class="mw-page-title-main">Brachyopini</span> Tribe of flies

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.

<span class="mw-page-title-main">Milesiini</span> Tribe of flies

The Milesiini is a large and diverse tribe of hoverflies. They mimic wasps or hornets.

<i>Milesia</i> (fly) Genus of flies


Milesia is a genus of very large hoverflies, which mimic social wasps. For example, the European species Milesia crabroniformis is a convincing mimic of the hornet species Vespa crabro. Milesia are predominantly Palaeotropical in distribution almost entirely Oriental.

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.
