Chironomidae (informally known as chironomids or non-biting midges) are 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 elongate mouthparts of the culicidae.
Midge, female, in the subfamily chironominae, family chironomidae (the midges).
They can be distinguished from mosquitoes because, unlike mosquitoes, they do not bite and lack scales on their wings. In colder regions, the midge larvae may over-winter in the pupa stage within the sediment.
The dipteran family chironomidae is the most widely distributed and frequently the most abundant group of insects in freshwater, with rep resentatives in both terrestrial and marine environments.
Midge flies are often confused with mosquitoes because of their appearance and similar habitats, but what are midges? they are small insects that are commonly found near water sources like lakes or rivers. Non-biting midges (chironomidae midges) can be 1/16 to 1/2 inch long. Biting midges are much smaller (only up to 1/8 of an inch long).
Chironomid larvae, of which the most familiar are the 'bloodworms' of chironomus (fig. 1), are to be found in almost every conceivable fresh and brackish-water.
Midges are also called “fuzzy bills” because of the male’s bushy antennae these aquatic insects are tolerant of a wide range of environmental conditions. Chironomid midges can be found in swift moving streams, deep slow moving rivers, stagnant ditches, and in lakes and ponds that are rich in decomposing organic matter.
The dipteran family chironomidae is the most widely distributed and frequently the most abundant group of insects in freshwater, with rep resentatives in both terrestrial and marine environments.
Non-biting midges of the genus paracladopelma harnisch (diptera: chironomidae) from the russian far east.
Midges are widely distributed in the united states and canada. The most common midges people complain about are non-biting nuisance pests belonging to the family chironomidae. Chironomus midges are similar in appearance to the mosquito, but they cannot bite.
In case of non-biting midges, everything is much wiser, as the nc state university specialists assure that most species of chironomid midges are highly desirable organisms in aquatic habitats. Midges are an important food source for fish and predatory aquatic insects.
Midges, in the family chironomidae, are mosquito doppelgangers. Midges hold their wings out to the side a bit when at rest, and mosquitoes tuck theirs over their backs. While either may rest with only four feet on the ground, mosquitoes raise their back pair of feet and midges tend to lift the front pair.
Non-biting midges (diptera: chironomidae) are ubiquitous and often abundant insects encountered everywhere, including even the antarctic (cranston, 1994a). The perception that adult fl ying midges can cause nuisance to humans is widespread, but it is rather subjective.
Biting midges, however, belong to the family ceratopogonidae, with over 6000 species globally. The most significant genus of biting midges within this family is culicoides. Over 1400 culicodies are identifiable, and at least 50 are carriers of nematodes, vectors, and protozoans.

Most look like mosquitoes or gnats and are commonly known by a variety of names: sandflies, no-see-ums, muckleheads, and black flies. No matter what they are called, they can be tough to control and practically impossible to eliminate entirely.
Chironomid larva, also referred to as “bloodworm” or “wriggler”. Between april and november when midge populations are highest blind mosquitoes can be an extreme nuisance, especially to residents living in breeding areas.
The family chironomidae includes a very large number of species the adult forms of which, in the great majority of cases, are very difficult to distinguish from each other. The adults of the larger species of the genus chironomus and those genera closely related to it are often mistaken for mosquitoes, which they greatly resemble in general appearance.
3 jun 2016 the aim of this study is to quantify the impacts of bioirrigating chironomid larvae ( diptera, chironomidae, chironomus plumosus group) on lake.
What does chironomidae mean? a taxonomic family within the order diptera — the chironomids or non-biting midges, a family of true flies widely distri.
Midges, midges, and more midge nymphs, they are everywhere! while there are plenty of effective nymph flies, the midge nymphs are probably the most predominant bug in every trout’s diet considering they hatch 365 days a year, including the winter and into the warm summer months. They exist in our lakes and most all rivers, however tail waters.
The chironomid home page is your place for finding researchers, news, and other resources regarding chironomidae (diptera), or non-biting midges. The webmaster would appreciate receiving any suggestions for further improving this site.
The potential of applying the analysis of freshwater midges (chironomidae) for current questions in geographical research is examined. Chironomids are cosmopolitan in distribution and frequently the most abundant insects found in freshwater ecosystems.
Family: chironomidae (midges) in the order diptera (flies) description midge fly larvae are thin, with cylindrical (not flattened), slightly curved, segmented bodies. These wormlike larvae of flies have a distinctly separate head, which is typically darker than the rest of the body. Overall coloration can be light olive green, tan, or clear, but some are bright red from the hemoglobin molecules within their narrow bodies; these red species are often called bloodworms.
Background: in the antarctic, only two species of chironomidae occur naturally-the wingless midge, belgica antarctica, and the winged midge, parochlus steinenii. Antarctica are desiccation- and freeze-tolerant and the adults are wingless.
Non-biting midge flies or chironomids commonly occur in both inland and coastal areas with natural and man-made bodies of water.
The dipteran family chironomidae is the most widely distributed and frequently the most abundant group of insects in freshwater, with rep resentatives in both terrestrial and marine.
Part of midges’ life cycle is aquatic, and part is terrestrial. Large populations of freshwater midges are often indicative of a system that is abundant in nutrients and contains high counts of algae. When midges emerge from their habitat, they come off in swarms, which can be a nuisance.
The chironomidae (informally known as chironomids, nonbiting midges, or lake flies) comprise a family of nematoceran flies with a global distribution.
The first larval instars may be planktonic and later instars.
The dipteran family chironomidae is the most widely distributed and frequently the most abundant group of insects in freshwater, with rep resentatives in both terrestrial and marine environments. A very wide range of gradients of temperature, ph, oxygen concentration, salinity, current velocity, depth, productivity, altitude and latitude have been exploited, by at least some chironomid species, and in grossly polluted environments chironomids may be the only insects present.
Midges can be found along the coast, shorelines, and banks of any body of water. Thanks to poor flying ability, they are at the mercy of wind currents and can be blown into backyards. For this reason, they may be considered a nuisance to homeowners.
Any of various small two-winged flies, for example, from the family chironomidae or non-biting midges, the family chaoboridae or phantom midges, and the family ceratopogonidae or biting midges, all belonging to the order diptera.
Midge, (family chironomidae), also called chironomid, nonbiting midge, or gnat, any of a group of tiny two-winged flies (order diptera) that superficially resemble mosquitoes. Although they resemble mosquitoes, midges are harmless, with small mouthparts that are not elongated into a piercing structure for blood feeding.

Being true flies, midges (in the family chironomidae) have only one pair of wings. They look a lot like mosquitoes: small and dainty, rather soft-bodied, with long, narrow wings and long, skinny legs; males often have feathery antennae, used for sensing the high-pitched sounds of female wings.
Midges and mosquitoes are different types of insects that often seek out the same resources, including egg incubation sites and opportunities for blood meals. As a result, midges can be just as much of a problem as mosquitoes. Luckily, what works against mosquitoes usually works against biting midges as well.
There are over 20,000 species known world-wide, including 2,000 in the nearctic. Adult midges are relatively small (1-20 mm long), with narrow bodies and long legs.
