Axymyiomorpha
The Nematoceran family Axymyiidae is the sole member of the infraorder Axymyiomorpha, though it is often included within the infraorder Bibionomorpha in older classifications. It is known from only nine species in four genera, plus eight fossil species. Family characteristics The Axymyiidae have the general appearance of the Bibionidae. Unlike bibionids, axymyiids have four branches of the radial vein, Bibionidae have two or three. The head is rounded. The eyes of the male are holoptic Holoptic refers to one of the ways in which the arthropod eye develops, particularly the eyes of various species of insects. Unlike dichoptic and cycloptic eyes, holoptic eyes meet along the median dorsal line of the head, in many species near ... for a considerable distance and divided into a larger dorsal part consisting of large facets and (separated by a groove) a smaller ventral part of smaller facets. The eyes of the female are separated by a broad frons and consist of separated face ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Axymyia'' is a genus of 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 "sh ...n flies in the family Axymyiidae. It contains only one described species, ''Axymyia furcata'', from eastern North America. A second species, ''Axymyia japonica'' , is sometimes listed, but this species is now generally placed in the related genus '' Protaxymyia''.

Bibionomorpha
The Bibionomorpha are an infraorder of the suborder Nematocera. One of its constituent families, the Anisopodidae, is the presumed sister taxon to the entire suborder Brachycera. Several of the remaining families in the infraorder (those shown without common names) are former subfamilies of the Mycetophilidae, which has been recently subdivided. The family Axymyiidae has recently been removed from the Bibionomorpha to its own infraorder Axymyiomorpha. Most representatives of the Bibionomorpha are saprophages or fungivores as larvae with the Cecidomyiidae being predominantly gall-formers. Some sciarids are common indoor pests, developing large populations in potting soil that has become moldy from overwatering. The larvae of the Bibionidae sometimes migrate in large, snake-like masses to minimize dehydration while seeking a new feeding site. Extinct families The extinct bibionomorph fauna is: **Cascopleciidae ''Cascoplecia insolitis'', rarely known as the unicorn fly, is an ex ...

Raymond Corbett Shannon
Raymond Corbett Shannon (4 October 1894 – 7 March 1945) was an American entomologist who specialised in Diptera and medical entomology. Life and career Shannon was born in Washington D.C. He was orphaned as a child. His studies at Cornell University were interrupted by World War I, but he received his B.S. from there in 1923. He was employed by the U.S. Bureau of Entomology from 1912–1916, and again from 1923–1925. In 1926, he began graduate studies at George Washington University, and from 1927 on he was employed by the International Health Division of the Rockefeller Foundation. He published over 100 articles on the characteristics, environment and behavior of insects and on their aspects as disease vectors. One of his discoveries, in 1930, was of the arrival of '' Anopheles gambiae'', the mosquito that carries malaria, into the New World. On his death at the age of 50, he left his library and insect collection to the Smithsonian Institution. His wife was Elnora Pet ...
