picture info	Thomas Say Thomas Say (June 27, 1787 – October 10, 1834) was an American entomologist, conchologist, and Herpetology, herpetologist. His studies of insects and shells, numerous contributions to scientific journals, and scientific expeditions to Florida, Georgia, the Rocky Mountains, Mexico, and elsewhere made him an internationally known naturalist. Say has been called the father of American descriptive entomology and American conchology. He served as librarian for the Academy of Natural Sciences of Philadelphia, curator at the American Philosophical Society (elected in 1817), and professor of natural history at the University of Pennsylvania. Early life and education Born in Philadelphia into a prominent Religious Society of Friends, Quaker family, Thomas Say was the great-grandson of John Bartram, and the great-nephew of William Bartram. His father, Dr. Benjamin Say, was brother-in-law to another Bartram son, Moses Bartram. The Say family had a house, "The Cliffs" at Gray's Ferry Bridge, ...

picture info	Moses Harris Moses Harris (15 April 1730 – 1787) was an English entomologist and engraver. Life and work Harris was encouraged in entomology from a young age by his uncle, a member of the Society of the Aurelians. In 1762 he became secretary of a second Society of Aurelians. He was a skilled artist, displaying some of his insect drawings at the Royal Academy in 1785. He drew and engraved illustrations for books including Dru Drury's ''Illustrations of Natural History'' (3 volumes, 1770–1782) and John Coakley Lettsom's ''The Naturalist's and Traveller's Companion'' (1772). Colour theory In "The Natural System of Colours" published in 1766, Harris discussed the multitude of colours that can be created using three "grand or principle" colours: red, yellow and blue. As a naturalist and an engraver, Harris focussed on the relationships between colours and how they are coded and created. He explained how three colours can be íntermixed, tinted and shaded to create 660 colours "materially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Charles Willison Johnson Charles Willison Johnson (October 26, 1863 – July 19, 1932) was an American naturalist who specialized in entomology (especially Diptera) and malacology, making significant contributions in both fields. He was a mentor and inspiration to many students and young scientists such as William J. Clench (who founded a publication named '' Johnsonia'' in his honor). Johnson was Curator of the Wagner Free Institute of Science, 1888–1903, then was Principal Curator at the Boston Society of Natural History, 1903–1932. He assisted Henry Augustus Pilsbry with '' The Nautilus'', an important American malacological publication. Although both were credited on the title page as "Editors and Publishers", Johnson was the business manager and Pilsbry was the editor, with Johnson acting as editor when Pilsbry was on extended field expeditions. Biography Charles Johnson was born to Albert Fletcher Johnson and Sarah Willison Johnson in Morris Plains, New Jersey. He attended public and private ...

picture info	Hermann Loew Friedrich Hermann Loew (19 July 1807 – 21 April 1879) 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. Biography Early years Hermann Loew was born in Weissenfels, Saxony a short distance south of Halle (Germany). The Loew family, though not wealthy, was well-placed. Loew's father was a functionary for the Department of Justice of the Duchy of Saxony who later became a ''Geheimer Regierungsrath'' of Prussia. Between 1817 and 1829 Loew attended first the Convent school of Rossleben, then the University of Halle-Wittenberg, graduating in mathematics, philology and natural history. Teacher, tutor and husband Recognizing his abilities as a mathematician, the university, on his graduation, appointed him as a lecturer in the same subjects. In 1830 he went to Berlin and gave lessons in differen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Psilidae The Psilidae are family of flies. Commonly called the rust flies, at least 38 species are in four genera. The carrot fly (''Chamaepsila rosae'') is a member of this group. They are found mainly in the Holarctic. Description For terms see Morphology of Diptera These are small or medium-sized (1.5 mm.-10 mm.) flies with slender bodies. They are yellow to reddish, brown or black in colour. The head is spherical with (relatively) small eyes and the face is often slanted backward. The antennae are small, with the third antennal segment conspicuously elongated. The arista has a short or long pubescence. The postvertical bristles are divergent or absent. Ocelli and ocellar bristles are present. Vibrissae are always absent. Up to two pairs of frontal bristles and scattered interfrontal setulae are present. The costa is interrupted at some distance from R1 and only the basal part of the subcosta is developed. The vein bordering the anal cell is straight on the outer side. Crossve ...

picture info	Diptera Of North America Flies are insects of the order Diptera, the name being derived from the Greek δι- ''di-'' "two", and πτερόν ''pteron'' "wing". Insects of this order use only a single pair of wings to fly, the hindwings having evolved into advanced mechanosensory organs known as halteres, which act as high-speed sensors of rotational movement and allow dipterans to perform advanced aerobatics. Diptera is a large order containing an estimated 1,000,000 species including horse-flies, crane flies, hoverflies and others, although only about 125,000 species have been described. Flies have a mobile head, with a pair of large compound eyes, and mouthparts designed for piercing and sucking (mosquitoes, black flies and robber flies), or for lapping and sucking in the other groups. Their wing arrangement gives them great maneuverability in flight, and claws and pads on their feet enable them to cling to smooth surfaces. Flies undergo complete metamorphosis; the eggs are often laid on the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
