The Culicomorpha are an infraorder of Nematocera, including mosquitoes, black flies, and several extant and extinct families of insects. They originated 176 million years ago, in the Triassic period. There are phylogenetic patterns that are used to interpret bionomic features such as differences in the nature of blood-feeding by adult females, daytime or nighttime feeding by adult females, and occurrence of immature stages in aquatic habitats.
A midge is any small fly, including species in several families of non-mosquito nematoceran Diptera. Midges are found on practically every land area outside permanently arid deserts and the frigid zones. Some midges, such as many Phlebotominae and Simuliidae, are vectors of various diseases. Many others play useful roles as prey for insectivores, such as various frogs and swallows. Others are important as detritivores, and form part of various nutrient cycles. The habits of midges vary greatly from species to species, though within any particular family, midges commonly have similar ecological roles.
Sandfly or sand fly is a colloquial name for any species or genus of flying, biting, blood-sucking dipteran (fly) encountered in sandy areas. In the United States, sandfly may refer to certain horse flies that are also known as "greenheads", or to members of the family Ceratopogonidae. The bites usually result in a small, intensely itchy bump or welt, the strength of which intensifies over a period of 5-7 days before dissipating. Sandfly bites can be distinguished from mosquito bites as sandfly bite are usually found in clusters as they attack animals in groups. Moderate relief is achieved with varying success through the application of over-the-counter products such as Benadryl (ingested) or an analgesic cream such as After Bite. Outside the United States, sandfly may refer to members of the subfamily Phlebotominae within the Psychodidae. Biting midges (Ceratopogonidae) are sometimes called sandflies or no-see-ums. New Zealand sandflies are in the genus of sand fly Austrosimulium, a type of black fly.
Culicoides imicola is a species of Ceratopogonidae that transmits the bluetongue virus (BTV) and the African horse sickness virus. This particular species has been recorded in Africa, Asia and Europe. African midges feed on animal blood, including horse, cattle, and sheep. Unlike other species within the Culicoides genus, this species prefers drier habitats for egg laying but retains a preference for moist soil to support larvae growth. Other suspected BTV vectors are Culicoides (Culicoides) pulicaris and species in the Culicoides (Avaritia) obsoletus complex.
The Nematocera are a suborder of elongated flies with thin, segmented antennae and mostly aquatic larvae. This group is paraphyletic and contains all flies except for species from suborder Brachycera, which includes more commonly known species such as the housefly or the common fruit fly. The equivalent clade to Nematocera is the whole Diptera, with Brachycera as a subclade. Families in Nematocera include mosquitoes, crane flies, gnats, black flies, and multiple families commonly known as midges. The Nematocera typically have fairly long, fine, finely-jointed antennae. In many species, such as most mosquitoes, the female antennae are more or less threadlike, but the males have spectacularly plumose antennae.
Ceratopogonidae is a family of flies commonly known as no-see-ums, or biting midges, generally 1–3 millimetres in length. The family includes more than 5,000 species, distributed worldwide, apart from the Antarctic and the Arctic.
Culicoides is a genus of biting midges in the family Ceratopogonidae. There are over 1000 species in the genus, which is divided into many subgenera. Several species are known to be vectors of various diseases and parasites which can affect animals. The genus has a long fossil record, with earliest known fossils being from Burmese amber, around 99 million years old.
Haemoproteus is a genus of alveolates that are parasitic in birds, reptiles, and amphibians. Its name is derived from Greek: haima 'blood' and Proteus, a sea god that had the power to assume various shapes. The name Haemoproteus was first used in the description of H. columbae in the blood of the pigeon Columba livia by Walther Kruse in 1890. This was also the first description of this genus. Two other genera—Halteridium and Simondia—are now considered to be synonyms of Haemoproteus.
Culicoides paraensis is a species of midge found from the northern United States to Argentina, which acts as the vector of the Oropouche fever virus.
Culicoides obsoletus the name of a species of midges in the subgenus Avaritia. According to a molecular phylogeny, Avaritia is monophyletic, and Culicoides obsoletus, Culicoides scoticus and Culicoides chiopterus should be part of the Obsoletus complex whereas Culicoides dewulfi should be excluded from it.
Leptoconops is a midge genus in the family Ceratopogonidae. It has a mostly tropical or subtropical distribution worldwide, but some species occur as far north as Moscow region in Russia and the Yukon Territory in Canada.
Culicoides bolitinos is an African species of bloodsucking fly that breeds in the dung of the African buffalo, the blue wildebeest, and cattle (Bosraces). It is considered a possible vector for African horse sickness. It is closely related to Culicoides imicola.
Forcipomyia is a genus of biting midges in the subfamily Forcipomyiinae. Species of the subgenus Lasiohelea suck vertebrate blood. Some species are ectoparasites on larger insects. Other species in the genus are important pollinators of the cacao tree. There are at least 1,000 described species in Forcipomyia.
Atrichopogon is a genus of biting midges, small flies in the family Ceratopogonidae.
Culicoides selandicus is a species of midges found in Scandinavia. It can be differentiated from its cogenerated by wing and maxillary palp characteristics.
Culicoides kalix is a species of midges found in Scandinavia. It can be differentiated from its cogenerated by wing and maxillary palp characteristics.
Verticia is a genus of flies (Diptera) in the family Calliphoridae. The genus was first described by J.R. Malloch in 1927.
Leptoconops nosopheris is an extinct species of biting midges belonging to the family Ceratopogonidae. This species was described from fossilized remains preserved in Burmese amber from the Early Cretaceous. The amber containing the fossil was mined in the Hukawng Valley, in Kachin State, Myanmar
Bezzia nobilis is a species of biting midges in the family Ceratopogonidae. It is widely considered one of the most common Bezzia species; it is found in Eurasian regions, all over the United States, Central America, and even into South American countries like Brazil. B. nobilis seem to prefer aquatic environments; they are commonly observed in stagnant water pools in Eurasia regions and marshes in the southern United States. Adults of this species are easily distinguished by their black and yellow striped legs. Pupae are recognized by their brown bodies, abdominal spines, and respiratory horns. B. nobilis larvae are distinguished by brown heads and white bodies. Little information is known on their life cycle or mating habits. B. nobilis is a predatory species. While some research suggests they mainly feed on larvae of other insect species, experiments suggest they prefer immobile, easy prey such as dead adult flies, bacteria, and protozoa.
