Charles Howard Curran
Charles Howard Curran (20 March 1894 – 23 January 1972) was a Canadian entomologist who specialised in Diptera. Curran's main taxonomic interests were in brachyceran flies, particularly the flower flies Syrphidae, in which he described 723 species. From 1922 to 1928 he worked as a specialist service in Diptera Entomology of Canada. In 1928, he was hired by the American Museum of Natural History as Assistant Curator and, from 1947 until his retirement in 1960, as Curator of Insects and Spiders. In 1931, he donated his collection to that institution: it has 10,000 specimens representing about 1,700 species including 400 types. He received in 1933 a Doctorate of Science at the University of Montreal with a thesis entitled The Families and Genera of North American Diptera. He was vice-president of the New York Entomological Society The New York Entomological Society was founded in 1892. The Brooklyn Entomological Society merged with the Society in 1968. The Society publishes '' En ...

Parasyrphus Melanderi
''Parasyrphus melanderi'' is a flower fly (family Syrphidae) that is best known as a larval predator on the leaf beetle ''Chrysomela aeneicollis'' in the Sierra Nevada range of California. Description Adults are medium-sized flies (approximately 6-11mm). The dorsal side of the fourth abdominal segment (and usually the third segment) have an entire yellow band (rather than black), and the face has a black median stripe. In males, the ventral side of the abdomen (sternites) has few or no distinct markings, and in females, the sternites have spots or triangles and the facial stripe is no more than one-quarter the as wide as the face. Eggs of ''P. melanderi'' are white and are smaller than the eggs of their prey ''Chrysomela aeneicollis'' in California. Mature ''P. melanderi'' larvae are 14–16mm long and approximately 3mm in diameter. Larvae have pale markings with thin dark brown stripes anterior to them. Range The holotype of this species was collected by Doctor Melander on Mount ...

James Edward Collin
James Edward Collin (16 March 1876, Kirtling – 16 September 1968) was an English entomologist who specialised in Diptera. He was the author of ''Empididae''. ''British Flies'', Volume 6. University Press, Cambridge (1961). This was the third volume in an uncompleted series begun by his uncle George Henry Verrall. Collin wrote extensively on Diptera of most families of Diptera (excepting those in Nematocera The Nematocera (the name means "thread-horns") are a suborder of elongated fly, flies with thin, segmented antenna (biology), antennae and mostly aquatic larvae. This group is paraphyletic and contains all flies but species from suborder Brachyce ...). The specimens collected by Collin and his uncle Verrall are in the Hope Entomological Collections at the University of Oxford. The OUM website provides a searchable database of the new species they described. He was a Fellow of the Royal Entomological Society and its president 1927–1928. References *Chvála, M. 197 ...
