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.

They breed in decaying organic materials such as run-offs from dung heaps ( Eristalis ) or in ponds and ditches (e.g. Anasimyia ). Some others, such as Myathropa and Mallota , breed in wet rotting tree stumps and rot holes.

A characteristic feature of this tribe is the "rat-tailed maggot" with a rear positioned telescopic breathing tube, allowing the larvae to breathe while living submerged in water or mud. This feature is also shared with another hoverfly tribe the Sericomyiini though those flies do not share the characteristic eristaline dip in wing vein R4+5. [1]

List of genera

Thompson [2] considers the tribe Sericomyiini a subtribe of the Eristalini while others separate it.

<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.

Paul Allen's flower fly is a flower fly found only in Costa Rican forests in the central highlands. It was named after Paul Allen. Another fly was also named after Allen's associate Bill Gates, Bill Gates' flower fly.

<i>Eristalis</i> Genus of flies

Eristalis is a large genus of hoverflies, family Syrphidae, in the order Diptera. Several species are known as drone flies because they bear a resemblance to honeybee drones.

<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.

<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>Eristalis horticola</i> Species of fly

Eristalis horticola is a Palearctic species of hoverfly.

<i>Myathropa florea</i> Species of fly

Myathropa florea, sometimes referred to as the Batman hoverfly, is a very common European and North African species of hoverfly. Adults may be seen on flowers from May to September. It is of a similar size to the common drone fly, but Myathropa are generally more yellow, with two light bands to the thorax, interrupted with a black central smudge. In museum specimens, any yellow colour soon fades to brown after death. Like most species in the tribe Eristalini, Myathropa are rather variable in size, shape and colour.

<i>Eristalinus</i> Genus of flies

Eristalinus is a genus of hoverfly. Most species have very distinctive eye marking in the form of spots or banding, though these features may fade on some preserved specimens. Most are stout flies, and are nimble flyers, even compared to other hoverfly species.

<i>Dasysyrphus</i> Genus of flies

Dasysyrphus is a genus of hover flies with 50 identified species distributed worldwide. While the genus is relatively easy to identify, genera key the differences between species have a more narrow range of variations. Therefore, identification of species by images of specimens alone should be made with care.

Austalis is a genus of Hoverflies, from the family Syrphidae, in the order Diptera.

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

Sericomyiini is a tribe of hoverflies consisting mainly of large bumblebee or wasp mimics. As with Eristalini the larvae have a telescopic breathing tube which allows them to breathe while submerged in boggy areas.

Habromyia is a genus of around 3 Neotropical hoverflies.

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.

<i>Eristalis bellardii</i> Species of fly

Eristalis bellardii, the Mexican mountain drone fly, is an uncommon species of syrphid fly first officially described by Jaennicke in 1867. It is infrequently found in the Southwestern United States, Mexico and Central America. In appearance it is somewhat like that of a honeybee. 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.

<i>Eristalis hirta</i> Species of fly

Eristalis hirta, the black-footed drone fly, is a common Western North American species of syrphid fly, first officially described by Loew in 1866. Hoverflies get their names from the ability to remain nearly motionless while in flight. The adults are also known as flower flies as they are commonly found on and around flowers, from which they get both energy-giving nectar and protein-rich pollen. The larvae are aquatic filter-feeders of the rat-tailed type.

<span class="mw-page-title-main">Eristalina</span> Subtribe of hoverflies

Eristalina is a subtribe of hoverflies with 17 genera. Several species are well-known bee mimics, such as the drone fly. The larvae live in aquatic and moist organic material, often with low oxygen levels using a posterior breathing tube, thus the common name—the "rat-tailed maggot".

Total of 245 species either found or highly expected to be found in New York.
