George Henry Horn
George Henry Horn (April 7, 1840 – November 24, 1897) was a U.S. entomologist who specialized in the study of beetles. Born in Philadelphia, Horn attended the University of Pennsylvania, from which he graduated with a degree in medicine in 1861. From 1862 to 1866, he served in the American Civil War as surgeon to the infantry of the California Volunteers, during which time he collected insects extensively in California, Arizona, and New Mexico. He then returned to Philadelphia, where he established a medical practice, specializing in obstetrics, and was elected president of the Entomological Society of Philadelphia, the predecessor of the American Entomological Society. He would remain president of the latter society until his death. He was elected as a member of the American Philosophical Society in 1869. Working with the collection he had made during his service in the West, he published "more than 150 important papers, in addition to very many minor notes; in these papers a ...

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 ...

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 ...
