thumbnail, Female '' Chrysotoxum bicinctum'' The genus ''Chrysotoxum'' (Meigen, 1803) consists of large, wasp-mimicking species. The adults are distinguished by very long antennae, oval abdomen with yellow stripes, and yellow patterns on the thoracic pleurae (sides of the thorax). The species of ''Chrysotoxum'' are chiefly Holarctic in distribution. . The species in this genus, are mostly very uniform in structure and colour and are separated with difficulty. Larvae are specialized in preying upon root aphids associated with ant nests. Taxonomy ''Chrysotoxum'' is the only genus in the tribe Chrysotoxini Features common to this genus are: The head is slightly wider than the thorax. The eyes are more or less pubescent and are contiguous (contacting each other medially) in males and widely separated in females.

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, o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Biography Müller was born in Copenhagen. He was educated for the church, became tutor to a young nobleman, and after several years' travel with him, settled in Copenhagen in 1767, and married a lady of wealth.

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 Fly, flies, mosquitoes, gnats and midges. He described many world species and was the first specialist to work on the Diptera of the United States.

Francis Walker (entomologist)
Francis Walker (31 July 1809 – 5 October 1874) was an English entomologist. He was born in Southgate, London, on 31 July 1809 and died at Wanstead, England on 5 October 1874. He was one of the most prolific authors in entomology, and stirred controversy during his later life as his publications resulted in a huge number of junior synonyms. However, his assiduous work on the collections of the British Museum had great significance. Between June 1848 and late 1873 Walker was contracted by John Edward Gray Director of the Natural History Museum, London, British Museum to catalogue their insects (except Coleoptera) that is Orthoptera, Neuroptera, Hemiptera, Diptera, Lepidoptera and Hymenoptera. Walker largely accomplished this and (Edwards, 1870) wrote of the plan and by implication those who implemented it: It is to him [Gray] that the Public owe the admirable helps to the study of natural history which have been afforded by the series of inventories, guides, and nomenclatures, ...

Early life, family and education Camillo Rondani was born in Parma when the city was part of the French Empire Napoleon having crowned himself King of Italy. The Rondani family were wealthy landowners and of "rich and of ancient origins" with ecclesiastical connections preliminary. Camillo's early education was in a seminary. He then passed into the public school system where, encouraged by Macedonio Melloni his physics and chemistry teacher in the preparatory course for the University of Parma, he did not attend the law lessons though his family had insisted. He attended mineralogy classes given by a Franciscan priest Father Bagatta and was taught natural history, a complementary course to botany for Medicine and Pharmacy. The Reader of Botany to the Athenaeum Parmesan was Professori Giorgio Jan, assistant at the Imperial Museum in Vienna and h ...
