Deuterophlebiidae
The fly genus ''Deuterophlebia'' is the sole member of the small monogeneric family Deuterophlebiidae or mountain midges. Adults have broad, fan-shaped wings, and males have extremely long antennae which they employ when contesting territories over running water, waiting for females to hatch. Larvae occur in swiftly flowing streams and are easily recognized by their forked antennae and the prolegs on the abdomen. One classification places this family in its own infraorder Deuterophlebiomorpha, but this has not gained wide acceptance. A recent phylogeny of the entire order Diptera places them as the sister group to all other flies. Species Catalogue of Life accepts the following species within ''Deuterophlebia:'' * ''Deuterophlebia bicarinata'' Courtney, 1994 * '' Deuterophlebia blepharis'' Courtney, 1994 * ''Deuterophlebia brachyrhina'' Courtney, 1994 * ''Deuterophlebia coloradensis'' Pennak, 1945 * ''Deuterophlebia inyoensis'' Kennedy, 1960 * ''Deuterophlebia mirabilis'' Ed ...

Blephariceridae
The Blephariceridae, commonly known as net-winged midges, are a nematoceran family (biology), family in the order Fly, Diptera. The adults resemble tipulidae, crane flies except with a projecting anal angle in the wings, and different head shape, absence of the V on the mesonotum, and more laterally outstretched, forward-facing legs. They are uncommon, but dozens of genera occur worldwide, and over 200 species. They are found near fast-flowing streams where the larvae live. Blepharicerid larvae are filter feeders and have suckers on their abdominal sternites, used to adhere to rocks in the torrents in which they live. These suckers are sometimes called creeping welts. These are of unique evolutionary origin within the Diptera. One recent classification based largely on fossils treats this family as the sole member of its infraorder, but this has not gained wide acceptance.

Nymphomyiidae
The Nymphomyiidae are a family of tiny (2 mm) slender, delicate flies (Diptera). Larvae are found among aquatic mosses in small, rapid streams in northern regions of the world, including northeastern North America, Japan, the Himalayas, and eastern Russia. Around a dozen extant species are known, with two fossil species found in amber, extending back to the Mid Cretaceous. Under an alternative classification, they are considered the only living representatives of a separate, suborder called Archidiptera (or Archaediptera) which includes several Triassic fossil members. The family has characteristics associated with the Nematocera as well as the Brachycera. The antennae are shortened as in the Brachycera and these flies are long, having a snout with vestigeal mouthparts, non-differentiated abdominal segments with large cerci. The wings are narrow and hair-fringed and have very weak venation. They are known to form cloud-like swarms in summer and the short-lived non-feeding adul ...

Nematocera
The Nematocera (the name means "thread-horns") are a suborder of elongated flies with thin, segmented antennae and mostly aquatic larvae. This group is paraphyletic and contains all flies but species from suborder Brachycera (the name means "short-horns"), which includes more commonly known species as housefly or the common fruit fly. Families in Nematocera include mosquitoes, crane flies, gnats, black flies, and a multiple groups of families described 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. The larvae of most families of Nematocera are aquatic, either free-swimming, rock-dwelling, plant-dwelling, or luticolous. Some families however, are not aquatic; for instance the Tipulidae tend to be soil-dwelling and the Mycetophilidae feed on fungi such as mushrooms. Unlike most of the Brachycera, the ...

Infraorder (biology)
Order ( la, wikt:ordo#Latin, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between Family_(biology), family and Class_(biology), class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. Fo ...

Fossil
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the ...
