The Chamaemyiidae are a small family of acalyptrate flies with less than 200 species described worldwide. The larvae of these small flies are active and predatory and are often used for biological control of aphids, scale insects, and similar pests. Chamaemyiid fossils are poorly represented in amber deposits, but a few examples are known from the Eocene epoch onwards.

For terms, see Morphology of Diptera
The Chamaemyiidae are small flies 9 (1–5 mm), usually greyish in colour. The frons is wide, with at most two pairs of bristles (often bare). The face is gently concave or strongly receding. Oral vibrissae are absent and the postvertical bristles are convergent or absent. The proboscis is short and the antennae are short. The mesonotum is with or without bristles. Prothoracic bristles are absent and with one sternopleural bristle. The mesopleura are usually bare, rarely setulose. The front femora bear bristles. The tibiae are without preapical bristles. Wings with the subcosta are entire, sometimes touching the first vein before its end. The anal vein does not reach nearly to the wing margin, the anal and second basal cells are always complete, and the costa is not broken. The abdomen is short or slightly elongated.
Data related to Chamaemyiidae at Wikispecies
The Acalyptratae or Acalyptrata are a subsection of the Schizophora, which are a section of the order Diptera, the "true flies". In various contexts the Acalyptratae also are referred to informally as the acalyptrate muscoids, or acalyptrates, as opposed to the Calyptratae. All forms of the name refer to the lack of calypters in the members of this subsection of flies. An alternative name, Acalypterae is current, though in minority usage. It was first used by Justin Pierre Marie Macquart in 1835 for a section of his tribe Muscides; he used it to refer to all acalyptrates plus scathophagids and phorids, but excluding Conopidae.
The confusing forms of the names stem from their first usage; Acalyptratae and Acalyptrata actually are adjectival forms in New Latin. They were coined in the mid 19th century in contexts such as "Muscae Calyptratae and Acalyptratae" and "Diptera Acalyptrata", and the forms stuck.The Acalyptratae are a large assemblage, exhibiting very diverse habits, with one notable and perhaps surprising exception: no known acalyptrates are obligate blood-feeders (hematophagous), though blood feeding at various stages of the life history is common throughout other Dipteran sections.Chamaemyia

The Lauxanioidea are a superfamily of flies that includes the two large families, the Lauxaniidae and Chamaemyiidae, and the small family Celyphidae. Generally, they are small to medium, densely populated, coloured flies. The Chamaemyiidae and Cremifaniidae live as parasites on insects. The family Celyphidae look like beetles.
Some authors also recognize the family Cremifaniidae, but most place this in the Chamaemyiidae.Leander Czerny
Leander (Franz) Czerny (4 October 1859, in Modřice, Moravia – 22 November 1944, in Pettenbach (de), Upper Austria) was an Austrian entomologist mainly interested in Diptera.
Czerny, who wrote extensively on Diptera between 1900 and 1939, describing many genera and species, was a major contributor to Erwin Lindner's Die Fliegen der paläarktischen Region ("The Flies of the Palaearctic Region"), the most significant work on the group in the 20th century.
Czerny wrote the sections on the following families:-
Heleomyzidae, Trichoscelidae, Chyromyidae (1927)
Anthomyzidae, Opomyzidae, Tethinidae, Clusiidae (1928)
Micropezidae (Tylidae), Neridrinae, Platypezidae (as Clythiidae), Dryomyzidae, Neottiophilidae (1930)
Lauxaniidae (Sapromyzidae) (1932)
Musidoridae (Lonchopteridae), Lonchaeidae (1934)
Chamaemyiidae (Ochthiphilidae) (1936)He was also abbot of the Benedictine Kremsmünster Abbey from 1905 to 1929 and collected there as well as in Pettenbach on the Upper Danube. As well as Diptera he collected Lepidoptera. His collections of both are now in the Natural History Museum in Vienna.Leucopis
