Friedrich Georg Hendel (14 December 1874 in Vienna – 26 June 1936 in Baden bei Wien) was an Austrian high school director and entomologist mainly interested in Diptera. He described very many new species and made important contributions to the higher taxonomy of the Diptera.
His collection is in the Vienna Natural History Museum.

Friedrich Hermann Loew was a German entomologist who specialised in the study of Diptera, an order of insects including flies, mosquitoes, gnats and midges. He described many world species and was the first specialist to work on the Diptera of the United States.
The Ulidiidae or picture-winged flies are a large and diverse cosmopolitan family of flies (Diptera), and as in related families, most species are herbivorous or detritivorous. They are often known as picture-winged flies, along with members of other families in the superfamily Tephritoidea that have patterns of bands or spots on the wings. Some species share with the Tephritidae an unusual elongated posteroapical projection of the anal cell in the wing, but can be differentiated by the smoothly curving subcostal vein. Two species, Tetanops myopaeformis and Euxesta stigmatias, are agricultural pests.

Oswald Duda, full name Pavel Theodor Friedrich Oswald Duda was a German entomologist mainly interested in Diptera.
Ferdinand Kowarz, was a Bohemian-Austrian entomologist who described many new species of Diptera mainly from central Europe

Paul Stein (1852–1921) was a German museum curator and entomologist. He specialised in Diptera especially the family Anthomyiidae. In this group he studied the world fauna describing many new genera and species.
Urophora is a genus of tephritid or fruit flies in the family Tephritidae.
Rhochmopterum is a genus of tephritid or fruit flies in the family Tephritidae.
Otitinae is the name of a subfamily of flies in the family Ulidiidae. It was formerly the Otitidae. Like the Ulidiinae, most species are herbivorous or saprophagous. Most species share with the Tephritidae an unusual elongated projection of the anal cell in the wing, but can be differentiated by the smoothly curving subcostal vein. Most are dull gray to shiny brown or black flies with vein R1 setulose or, in a few cases, bare.
Goniurellia is a genus of tephritid or fruit flies in the family Tephritidae.
Hydrophorinae is a subfamily of flies in the family Dolichopodidae. Several molecular phylogenetic analyses of the family have found evidence that the subfamily in its current sense is polyphyletic.
Tephritis arnicae is a species of picture-winged fly of the family Tephritidae, which are variously known as fruit-flies or gall flies.
Hydatostega is a genus of flies in the family Dolichopodidae. Most of its species are found in the Americas, where it is mainly restricted to montane habitats and high altitudes or latitudes, while three species are known from Tristan da Cunha, a group of islands in the South Atlantic Ocean. Hydatostega was formerly considered a synonym of Hydrophorus, but was recently restored as a separate genus.
Tephritini is a tribe of fruit flies in the family Tephritidae. There are about 80 genera and some 1000 described species in Tephritini.
Chymomyza is a genus of vinegar flies.
Myrmecothea is a genus of picture-winged flies in the family Ulidiidae.
Urophora tenuior is a species of tephritid or fruit flies in the genus Urophora of the family Tephritidae.
Scionini is a tribe of horse and deer flies in subfamily Pangoniinae of family Tabanidae.
Cephaliini is a tribe of picture-winged flies in the family Ulidiidae.
Chaetonerius is a genus of flies in the family Neriidae.
Histiodroma is a genus of flies in the family Stratiomyidae.
