Synoeca Septentrionalis
''Synoeca septentrionalis'' is one of five species of wasps in the genus '' Synoeca''. It is a swarm-founding wasp that is also eusocial, exhibiting complicated nest structure and defense mechanisms and a colony cycle including a pre-emergence phase and a post-emergence phase. It is typically found in areas from Central to South America. This wasp is one of the larger species of paper wasps and exhibits multiple morphological adaptations as a result of this. ''Synoeca septentrionalis'' is known for possessing a very painful sting. Taxonomy and phylogeny ''Synoeca septentrionalis'' is one of five species of wasp in the genus ''Synoeca'', with the other four being ''S. chalybea'', ''S. cyanea'', ''S. surinama'', and ''S. virginea''. Wasps in the genus ''Synoeca'' are often referred to as warrior wasps and are found in various areas in the Americas. Each wasp in the genus exhibits similar characteristics, but from a phylogenetic standpoint, ''S. septentrionalis'' is most closely rela ...

Owain Richards
Owain Westmacott Richards FRS (31 December 1901 – 10 November 1984) was a British entomologist and ecologist who worked as Professor of Zoology and Applied Entomology, Imperial College, London, based at Silwood Park, and an editor of the ''Journal of Animal Ecology''. Richards was born in Croydon, the second son of the town medical officer Harold Meredith and Mary Cecilia née Todd. His mother was interested in botany and natural history. He studied at St Cross School, Surrey and then as a boarder to Hereford Cathedral School and Brasenose College, Oxford studying mathematics before switching to zoology. He was a Senior Hulme Scholar and a Christopher Welch Scholar. He began to take an interest in British insects, collecting along with H. A. Hamm. His expertise in entomology was appreciated by teachers like Charles Elton. He worked as a research assistant at the Imperial College in the entomology department in 1927. He became a reader in 1937. It was here that he met Maud N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panama
Panama ( , ; es, link=no, Panamá ), officially the Republic of Panama ( es, República de Panamá), is a transcontinental country spanning the southern part of North America and the northern part of South America. It is bordered by Costa Rica to the west, Colombia to the southeast, the Caribbean Sea to the north, and the Pacific Ocean to the south. Its capital and largest city is Panama City, whose metropolitan area is home to nearly half the country's million people. Panama was inhabited by indigenous tribes before Spanish colonists arrived in the 16th century. It broke away from Spain in 1821 and joined the Republic of Gran Colombia, a union of Nueva Granada, Ecuador, and Venezuela. After Gran Colombia dissolved in 1831, Panama and Nueva Granada eventually became the Republic of Colombia. With the backing of the United States, Panama seceded from Colombia in 1903, allowing the construction of the Panama Canal to be completed by the United States Army Corps of En ...

Starr Sting Pain Scale
The Starr sting pain scale was created by the entomologist Christopher Starr as a scale to compare the overall pain of hymenopteran stings on a four-point scale, an expansion of the "pain index" originally created by Justin Schmidt. 1 is the lowest pain rating; 4 is the highest. Scale See also * Dol scale to measure pain * Irukandji syndrome, a jellyfish sting-induced condition * Pain scale * Schmidt sting pain index by Justin O.

Montezuma Oropendola
The Montezuma oropendola (''Psarocolius montezuma'') is a New World tropical icterid bird. It is a resident breeder in the Caribbean coastal lowlands from southeastern Mexico to central Panama, but is absent from El Salvador and southern Guatemala. It also occurs on the Pacific slope of Nicaragua and Honduras and northwestern and southwestern Costa Rica. It is among the oropendola species sometimes separated in the genus ''Gymnostinops''. The English and scientific names of this species commemorate the Aztec emperor Moctezuma II. Description Adult males are mainly chestnut with a blackish head and rump, and a tail which is bright yellow apart from two dark central feathers. There is a bare blue cheek patch and a pink wattle, the iris is brown, and the long bill is black at the base with a red tip. Females are similar, but smaller than males with a smaller wattle. Young birds are duller than adults and have a paler and less demarcated bill. No subspecies are currently recognize ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mandibles
In anatomy, the mandible, lower jaw or jawbone is the largest, strongest and lowest bone in the human facial skeleton. It forms the lower jaw and holds the lower tooth, teeth in place. The mandible sits beneath the maxilla. It is the only movable bone of the skull (discounting the ossicles of the middle ear). It is connected to the temporal bones by the temporomandibular joints. The bone is formed prenatal development, in the fetus from a fusion of the left and right mandibular prominences, and the point where these sides join, the mandibular symphysis, is still visible as a faint ridge in the midline. Like other symphyses in the body, this is a midline articulation where the bones are joined by fibrocartilage, but this articulation fuses together in early childhood.Illustrated Anatomy of the Head and Neck, Fehrenbach and Herring, Elsevier, 2012, p. 59 The word "mandible" derives from the Latin word ''mandibula'', "jawbone" (literally "one used for chewing"), from ''wikt:mandere ...

Gaster (insect Anatomy)
The gaster is the bulbous posterior portion of the metasoma found in hymenopterans of the suborder Apocrita ( bees, wasps and ants). This begins with abdominal segment III on most ants, but some make a constricted postpetiole out of segment III, in which case the gaster begins with abdominal segment IV. Certain ants in the genus '' Cataglyphis'', specifically ''Cataglyphis bicolor'' and ''Cataglyphis fortis'', have a cubiform petiole that allows them to decrease their inertia Inertia is the idea that an object will continue its current motion until some force causes its speed or direction to change. The term is properly understood as shorthand for "the principle of inertia" as described by Newton in his first law ... (and therefore increase their speed) by raising their gaster into an upright position. References Insect anatomy {{insect-anatomy-stub de:Gaster ...

Polybia Sericea
''Polybia sericea'' is a Eusociality#In insects, social, tropical wasp of the family (biology), family Vespidae that can be found in South America. It founds its colonies by swarming migrations, and feeds on nectar and arthropods. ''P. sericea'' is medium in size, and has a dark-colored body. The wasps build multitiered nests, and colony size can vary greatly between a few to a few thousand workers. Queens can be distinguished from workers by their greater body size and smaller head size. They tend to be Polygyny in nature, polygynous, meaning that several egg-laying queens are within a nest, with the result that workers are generally less related to each other than in other eusocial species. Workers are responsible for hunting and foraging, while queens are responsible for laying eggs, and have the most developed ovary, ovaries. When hunting for prey, workers rely heavily on visual and insect olfaction, olfactory cues. Prey include arthropods such as green and brown caterpillar ...
