George Alexander Ehrman
George Alexander Ehrman (2 February 1862,Pittsburgh- 30 January, 1926,Pittsburgh) was an American entomologist who specialised in Lepidoptera notably Papilionidae. Ehrman invented equipment which came into general use in the manufacture of blown and pressed glass for the Macbeth-Evans Glass Company and the United States Glass Company. In later years he was employed in the Research Laboratory of the Mesta Machine Company. Financially secure Ehrman was able during his later life to devote himself to natural history including ornithology. He made extensive collections of the Lepidoptera and Coleoptera of western Pennsylvania then extended his collections worldwide. He specialised in Papilionidae, the genus ''Catocala'', and the butterflies and moths of Liberia, and the beetle genus ''Cychrus'' and its allies. His collection of American und exotic Rhopalocera and Coleoptera was bequeathed to the Carnegie Museum of Natural History. The species described by him are listed by Holl ...

Entomologist
Entomology () is the scientific study of insects, a branch of zoology. In the past the term "insect" was less specific, and historically the definition of entomology would also include the study of animals in other arthropod groups, such as arachnids, myriapods, and crustaceans. This wider meaning may still be encountered in informal use. Like several of the other fields that are categorized within zoology, entomology is a taxon-based category; any form of scientific study in which there is a focus on insect-related inquiries is, by definition, entomology. Entomology therefore overlaps with a cross-section of topics as diverse as molecular genetics, behavior, neuroscience, biomechanics, biochemistry, systematics, physiology, developmental biology, ecology, morphology, and paleontology. Over 1.3 million insect species have been described, more than two-thirds of all known species. Some insect species date back to around 400 million years ago. They have many kinds of int ...

Lepidoptera
Lepidoptera ( ) is an order (biology), order of insects that includes butterfly, butterflies and moths (both are called lepidopterans). About 180,000 species of the Lepidoptera are described, in 126 Family (biology), families and 46 Taxonomic rank, superfamilies, 10 percent of the total described species of living organisms. It is one of the most widespread and widely recognizable insect orders in the world. The Lepidoptera show many variations of the basic body structure that have evolved to gain advantages in lifestyle and distribution. Recent estimates suggest the order may have more species than earlier thought, and is among the four most wikt:speciose, speciose orders, along with the Hymenoptera, fly, Diptera, and beetle, Coleoptera. Lepidopteran species are characterized by more than three derived features. The most apparent is the presence of scale (anatomy), scales that cover the torso, bodies, wings, and a proboscis. The scales are modified, flattened "hairs", and give ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Papilionidae
Swallowtail butterflies are large, colorful butterflies in the family Papilionidae, and include over 550 species. Though the majority are tropical, members of the family inhabit every continent except Antarctica. The family includes the largest butterflies in the world, the birdwing butterflies of the genus '' Ornithoptera''. Swallowtails have a number of distinctive features; for example, the papilionid caterpillar bears a repugnatorial organ called the osmeterium on its prothorax. The osmeterium normally remains hidden, but when threatened, the larva turns it outward through a transverse dorsal groove by inflating it with fluid. The forked appearance in some of the swallowtails' hindwings, which can be seen when the butterfly is resting with its wings spread, gave rise to the common name ''swallowtail''. As for its formal name, Linnaeus chose '' Papilio'' for the type genus, as ''papilio'' is Latin for "butterfly". For the specific epithets of the genus, Linnaeus applied ...

United States Glass Company
The United States Glass Company was a trust formed by the combination of numerous glass companies. The factories were located from western Pennsylvania to Indiana. History On February 9, 1891, the ''New York Times'' reported on the founding of the company, which included seventeen factories. After the companies combined, two new plants were built. One, an automatic facility, was constructed at Gas City, Indiana. A hand-worked glass operation was also added at Tiffin, Ohio. The plants all received a letter designation. The main office started at South 9th and Bingham Streets, Pittsburgh, PA, in the former Ripley Glass facility, and moved to Tiffin in 1938. Over time, the factories closed until only the Tiffin plant survived. The company went bankrupt in 1963, with the Tiffin plant reorganizing as the "Tiffin Art Glass Company". The other plant which survived to that point was the Glassport, Pennsylvania, plant. It was closed after a storm on August 3, 1963, which resulted in the f ...

Mesta Machinery
Mesta Machinery was a leading industrial machinery manufacturer based in the Pittsburgh area town of West Homestead, Pennsylvania. It was founded in 1898 by George Mesta when he merged his machine shop with another. Mesta "machines" can be found in factories throughout the world and as of 1984 had equipment in 500 steel mills. Mesta was the 488th largest American company in 1958 and the 414th largest in 1959. President Mesta By 1919 Mesta employed 3,000 at West Homestead and manufactured everything from ship propeller shafts to giant turbines for power plants and dams. In 1917, George's wife Perle Mesta wrote that the works "was a thrilling site, spread over many acres on the banks of the Monongahela." George Mesta died in 1925. President Wahr Harry F. Wahr was the handpicked successor to Mesta and his nephew. Wahr committed suicide in 1930. President Iversen Lorenz Iversen took over the company in 1930, leading it until December 31, 1963. One of the first things Iversen accomp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornithology
Ornithology is a branch of zoology that concerns the "methodological study and consequent knowledge of birds with all that relates to them." Several aspects of ornithology differ from related disciplines, due partly to the high visibility and the aesthetic appeal of birds. It has also been an area with a large contribution made by amateurs in terms of time, resources, and financial support. Studies on birds have helped develop key concepts in biology including evolution, behaviour and ecology such as the definition of species, the process of speciation, instinct, learning, ecological niches, guilds, island biogeography, phylogeography, and conservation. While early ornithology was principally concerned with descriptions and distributions of species, ornithologists today seek answers to very specific questions, often using birds as models to test hypotheses or predictions based on theories. Most modern biological theories apply across life forms, and the number of scientists ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catocala
''Catocala'' is a generally Holarctic genus of moths in the family Erebidae. The genus was erected by Franz von Paula Schrank in 1802. The moths are commonly known as underwing moths or simply underwings. These terms are sometimes used for a few related moths, but usually – especially when used in plural, not as part of a species name – they are used to refer to ''Catocala'' only. Of the more than 250 known species, slightly less than half are found in North America – mostly in the United States – while the rest occur in Eurasia. About one-fifth (almost 30) of these species are native to Europe. A few species occur in the northern Neotropics and Indomalaya. Description and ecology Most species of ''Catocala'' have medium to large adults, cryptically coloured except for the hindwings, which are marked with stripes in orange, red, white, or even blue. In some, the hindwings are mostly blackish. Unlike what the common name "underwings" seems to suggest, the colour is b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liberia
Liberia (), officially the Republic of Liberia, is a country on the West African coast. It is bordered by Sierra Leone to its northwest, Guinea to its north, Ivory Coast to its east, and the Atlantic Ocean to its south and southwest. It has a population of around 5 million and covers an area of . English is the official language, but over 20 indigenous languages are spoken, reflecting the country's ethnic and cultural diversity. The country's capital and largest city is Monrovia. Liberia began in the early 19th century as a project of the American Colonization Society (ACS), which believed black people would face better chances for freedom and prosperity in Africa than in the United States. Between 1822 and the outbreak of the American Civil War in 1861, more than 15,000 freed and free-born black people who faced social and legal oppression in the U.S., along with 3,198 Afro-Caribbeans, relocated to Liberia. Gradually developing an Americo-Liberian identity, the se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
