Ezra Townsend Cresson
Ezra Townsend Cresson, also Ezra Townsend senior (18 June 1838, in Byberry – 19 April 1926, in Swarthmore) was an American entomologist who specialised in the Hymenoptera order of insects. He wrote ''Synopsis of the families and genera of the Hymenoptera of America, north of Mexico'' Philadelphia: Paul C. Stockhausen, Entomological printer (1887) and many other works. His son Ezra Townsend, Jr. (1876–1948) was also an entomologist but a specialist in Diptera. Cresson also documented many new species including ''Nomada texana ''Nomada texana'' is a species of bee native to the southern and western United States and other parts of North America (including Mexico Mexico (Spanish language, Spanish: México), officially the United Mexican States, is a List of sover ...''.

Byberry, Philadelphia
Byberry is a neighborhood in the far northeast section of Philadelphia, in the U.S. state of Pennsylvania. Originally it was incorporated as the Township of Byberry and was the northeasternmost municipality of Philadelphia County before the City and County were consolidated in 1854. Its approximate boundaries are the Poquessing Creek to the north, Woodhaven Road to the south, the Roosevelt Boulevard to the west, and Thornton Road to the east. Byberry had a strong abolitionist presence and may have been an original stop on the Underground Railroad. Today, the area occupied by the township is mostly synonymous with the neighborhood of Somerton, as the neighborhoods of Byberry and Somerton tend to overlap. History A township in the extreme northeastern part of the County of Philadelphia; bounded on the east and northeast by Poquessing Creek and Bucks County; on the northwest by Montgomery County; and on the west and southwest by the Township of Moreland. Its greatest length was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swarthmore, Pennsylvania
Swarthmore ( , ) is a borough in Delaware County, Pennsylvania. Swarthmore was originally named "Westdale" in honor of noted painter Benjamin West, who was one of the early residents of the town. The name was changed to "Swarthmore" after the establishment of Swarthmore College. The borough population was 6,194 as of the 2010 census. History The borough was originally part of Springfield Township, and grew up around Swarthmore College, which was founded in 1864. The advent of passenger rail service from Philadelphia in the 1880s greatly enhanced the desirability of the borough as a commuter suburb, and the borough was incorporated in 1893. About one third of the borough's land area consists of the Swarthmore College campus. Many of the streets in the southern half of town are named for eastern colleges, and much of the borough's housing stock dates from the Victorian period through the 1920s. The Ogden House and Benjamin West Birthplace are listed on the National Register o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 intera ...

Hymenoptera
Hymenoptera is a large order (biology), order of insects, comprising the sawfly, sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are Parasitoid wasp, parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism (complete metamorphosis (biology), metamorphosis)—that is, they have a wormlike larval stage and an inactive pupal stage before they mature. Etymology The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous. All references agree that the derivation involves the Ancient Greek language, Ancient Greek wikt:πτερόν, πτερόν (''pteron'') for wing. The Ancient Greek wikt:ὑμήν, ὑμήν (''hymen'') for membrane provides a plausible etymology for the term bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ezra Townsend Cresson, Jr
Ezra (; he, עֶזְרָא, '; fl. 480–440 BCE), also called Ezra the Scribe (, ') and Ezra the Priest in the Book of Ezra, was a Jewish scribe (''sofer'') and priest (''kohen''). In Greco-Latin Ezra is called Esdras ( grc-gre, Ἔσδρας). According to the Hebrew Bible he was a descendant of Sraya, the last High Priest to serve in the First Temple, and a close relative of Joshua, the first High Priest of the Second Temple. He returned from Babylonian exile and reintroduced the Torah in Jerusalem. According to 1 Esdras, a Greek translation of the Book of Ezra still in use in Eastern Orthodoxy, he was also a High Priest. Rabbinic tradition holds that he was an ordinary member of the priesthood. Several traditions have developed over his place of burial. One tradition says that he is buried in al-Uzayr near Basra (Iraq), while another tradition alleges that he is buried in Tadif near Aleppo, in northern Syria. His name may be an abbreviation of ', "Yah helps". In the Gre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diptera
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 l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Edward Oliver Essig
Edward Oliver Essig (29 September 1884 Arcadia, Indiana – 23 November 1964, Lafayette, California) was an American entomologist who specialized in the Hemiptera. Essig was a professor at the University of California, Berkeley. He wrote ''Injurious and Beneficial Insects of California'' (1913), ''Insects of Western North America'' (1926), ''A History of Entomology'' (1931), ''College Entomology'' (1942) and several hundred scientific works on Hemiptera.The Essig Museum of Entomology at UC Berkeley is named for him. He was also interested in horticulture and wrote ''A check-list of Fuchsias''. American Fuchsia ''Fuchsia'' () is a genus of flowering plants that consists mostly of shrubs or small trees. The first to be scientifically described, ''Fuchsia triphylla'', was discovered on the Caribbean island of Hispaniola (Haiti and the Dominican Republic) ... Society (1936).
