Arctopelopia is a genus of non-biting midges of the bloodworm family Chironomidae. [1] The adipose tissue of the larvae of species in this genus are the host of Coccospora micrococcus , a microsporidium. [2]
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.
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.
The Chironomidae comprise a family of nematoceran flies with a global distribution. They are closely related to the Ceratopogonidae, Simuliidae, and Thaumaleidae. Many species superficially resemble mosquitoes, but they lack the wing scales and elongated mouthparts of the Culicidae.
Thaumaleidae, the solitary midges or trickle midges, are a group of nematoceran flies related to the Ceratopogonidae, Chironomidae, and the Simuliidae. They are small, stocky, yellow to brown flies (3–4 mm). Very few species are known for this family. Larvae are found in films on rocks and the nonfeeding adults are usually found on foliage along the same streams in which the larvae are found. A few solitary midges are found in the Southern Hemisphere, but Thaumaleidae are generally an Holarctic family.
Chaoboridae, commonly known as phantom midges or glassworms, is a family of fairly common midges with a cosmopolitan distribution. They are closely related to the Corethrellidae and Chironomidae; the adults are differentiated through peculiarities in wing venation.
The Chironomoidea are a superfamily within the order Diptera, suborder Nematocera, infraorder Culicomorpha. This superfamily contains the families Chironomidae, Ceratopogonidae, Simuliidae, and Thaumaleidae.
Polypedilum vanderplanki or the sleeping chironomid, is a dipteran in the family Chironomidae. It occurs in the semi-arid regions of the African continent. Its larvae are found in small tubular nests in the mud at the bottom of temporary pools that frequently dry out during the lifetime of P. vanderplanki larvae. Under these conditions, the larvae's body desiccates to as low as 3% water content by weight. In the dehydrated state the larvae become impervious to many extreme environmental conditions, and can survive temperatures from 3 K to up to 375 K, very high levels of gamma-rays, and exposure to vacuum. It is one of few metazoans that can withstand near complete desiccation (anhydrobiosis) in order to survive adverse environmental conditions. Slow desiccation enabled larvae to synthesize 38 μg trehalose/individual, and all of them recovered after rehydration, whereas larvae that were dehydrated 3 times faster accumulated only 6.8 μg trehalose/individual and none of them revived after rehydration. Late Embryo Abundant (LEA), anti-oxidant, and heat-shock proteins may also be involved in survival. This species is considered the most cold-tolerant insect species, able to survive liquid helium (−270 °C) exposure for up to 5 min. with a 100% survival rate when desiccated to 8% water content.
Chironomus is a genus of nonbiting midges in the subfamily Chironominae of the bloodworm family, Chironomidae, containing several cryptic species that can only be distinguished by experts based on the characteristics of their giant chromosomes. The larvae of several species inhabit the profundal zone where they can reach relatively high densities. They use a combination of hemoglobin-like proteins and undulatory movements in their burrows to obtain oxygen in poorly oxygenated habitats. Adults are up to 13 mm long, and males can be identified by their feather-like antennae.
Stictochironomus is a genus of non-biting midges in the subfamily Chironominae of the bloodworm family Chironomidae. Members of this genus often have strongly marked wings and legs. The larvae of these midges may also have distinct dark patterns on the dorsal side of the head capsule. They live in sand and other sediments in a variety of fresh water habitats in densities of several hundred per square meter.
Zavrelia is a genus of European non-biting midges in the subfamily Chironominae of the bloodworm family Chironomidae.
Buchonomyia is the only extant genus of the subfamily Buchonomyiinae of the non-biting midge family Chironomidae. There are three known extant species and one fossil species in the genus: Members of the genus are parasitic of psychomyiid caddisflies.
Tanypodinae is a subfamily of midges in the non-biting midge family (Chironomidae). The larvae are generally carnivorous and their mouthparts are adapted for predation on small invertebrates although 1st and 2nd instar larvae also feed on algae.
Pentaneurini is a tribe of midges in the non-biting midge family (Chironomidae).
Clunio marinus is a non-biting midge of the bloodworm family (Chironomidae). It is found in the intertidal zone of the European Atlantic Coast from Spain to Iceland. The species is a long-standing model system in chronobiology, particularly for circalunar clocks and the evolution of biological clocks. Its genome has been sequenced.
Pontomyia is a genus of flightless marine midges belonging to the subfamily Chironominae in the Chironomidae family. Insects in marine environments are extremely rare while flightlessness, extreme sexual dimorphism, and an extremely short adult life span contribute to making these midges unusual among insects. They are known from the shores of islands in the Indian, Atlantic and Pacific Oceans.
Chironomus riparius, also known as Chironomus thummi and commonly known as the harlequin fly, is a species of non-biting midge. Their larvae are known by the common name of blood worm due to their red colouration. It is common in both North America and Europe. The species was described in 1804 by Johann Wilhelm Meigen. C. riparius has been used extensively as a model for genome structure analysis in insects and is also used in toxicology tests and functional developmental genetic studies. Both their adult and larval forms have been implicated as disease vectors but are also an important part of freshwater food chains.
A gnat is any of many species of tiny flying insects in the dipterid suborder Nematocera, especially those in the families Mycetophilidae, Anisopodidae and Sciaridae. They can be both biting and non-biting. Most often they fly in large numbers, called clouds. "Gnat" is a loose descriptive category rather than a phylogenetic or other technical term, so there is no scientific consensus on what constitutes a gnat. Some entomologists consider only non-biting flies to be gnats. Certain universities and institutes also distinguish eye gnats: the Smithsonian Institution describes them as "non-biting flies, no bigger than a few grains of salt, ... attracted to fluids secreted by your eyes".
Chironomus zealandicus, commonly known as the New Zealand midge, common midge, or non-biting midge, is an insect of the Chironomidae family that is endemic to New Zealand. The worm-like larvae are known to fisherman and have a common name of blood worm due to their red color and elongated blood gills.
Chironomus annularius is a species of non-biting midge in the family Chironomidae. It is usually found in regions with bodies of fresh water but can be found in almost every environment. It tends to form "hotspots" around specific areas. The species is distinguished by the size of its chromosomes and the lack of a proboscis.
Tokunagayusurika akamusi is a midge fly species of the family Chironomidae, commonly called "nonbiting midges" or "lake flies."
