Frederick Ernst Melsheimer
Frederick Ernst Melsheimer, M.D. (1782–1873; first name also spelled Friedrich) was an American entomologist noted for his work on Coleoptera. He was President of the American Entomological Society in 1853. Frederick Ernest Melsheimer's most important work was ''Catalogue of the described Coleoptera of the United States'' (1853). His co-authors on that work were John LeConte and S.S. Haldeman. His father, Frederick Valentine Melsheimer The Reverend Frederick Valentine Melsheimer (September 25, 1749, Negenborn, Duchy of Brunswick, Brunswick – June 30, 1814, Hanover, Pennsylvania, Hanover, Pennsylvania) was a Lutheran clergyman and early United States, American entomologist, ca ...

Beetle
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trogidae
Trogidae, sometimes called hide beetles, is a family of beetles with a distinctive warty or bumpy appearance. Found worldwide, the family includes about 300 species contained in four or five genera. Trogids range in length from 2 to 20 mm. Their shape is oblong to oval, with a generally flat abdomen. Their color ranges from brown to gray or black, and they often encrust their bodies with soil. They resemble scarab beetles with heavy limbs and spurs. They are scavengers and are among the last species to visit and feed on carrion. They are most often found on the dry remains of dead animals. Both adults and larvae eat feathers and skin. Some species are found in bird and mammal nests. Details of the life histories of many species are poorly known, since many are specialized to particular types of nests. They are often overlooked by predators and collectors due to their behaviors of covering their bodies with soil and becoming motionless when disturbed. This group may also be con ...

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Trox
''Trox'' is a genus of hide beetle in the subfamily Troginae. Taxonomy In recent years, scientists have revamped the taxonomy of ''Trox''. The formerly massive genus, which boasted a whopping 160 species, has been cut down. Specifically, the subgenera '' Phoberus'' and '' Glyptotrox'' have been reelevated as their own separate genera, while various ''Trox'' species have been merged or otherwise combined. After taxonomic revisions, the genus ''Trox'' contains three subgenera - '' Trox (Trox)'', '' Trox (Niditrox)'', and '' Trox (Granulitrox)'' -, with the following species: Subgenus ''Trox'' *'' Trox acanthinus'' Harold, 1872 *'' Trox antiquus'' Wickham, 1909 *'' Trox cadaverinus'' Illiger, 1802 *'' Trox capillaris'' Say, 1824 *'' Trox contractus'' Robinson, 1940 *'' Trox coracinus'' Gmelin, 1788 *'' Trox cretaceus'' Nikolajev, 2007 *'' Trox floridanus'' Howden & Vaurie, 1957 *'' Trox gansuensis'' Ren, 2003 *'' Trox gemmulatus'' Horn, 1874 *'' Trox horiguchii'' Ochi & Kawahara ...

Taxa Named By Frederick Ernst Melsheimer
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
