Asian Giant Hornet
The Asian giant hornet (''Vespa mandarinia''), also known as the northern giant hornet, and the Japanese giant hornet, is the world's largest hornet. It is native to temperate and tropical East Asia, South Asia, mainland Southeast Asia, and parts of the Russian Far East. It was also found in the Pacific Northwest of North America in late 2019, with a few more additional sightings in 2020, and nests found in 2021, prompting concern that it could become an invasive species, but in December 2024, the hornets were announced to have been eradicated from the region, as well as from the rest of the United States.New York Times: Asian giant hornets prefer to live in low mountains and forests, while almost completely avoiding plains and high-altitude climates. ''V. mandarinia'' creates nests by digging, co-opting pre-existing tunnels dug by rodents, or occupying spaces near rotten pine roots. It feeds primarily on larger insects, colonies of other eusocial insects, tree sap, and honey fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miocene
The Miocene ( ) is the first epoch (geology), geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene followed the Oligocene and preceded the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and Ape, hominoids into Eurasia. During the late Miocene, the conn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wingspan
The wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the opposite wingtip. For example, the Boeing 777–200 has a wingspan of , and a wandering albatross (''Diomedea exulans'') caught in 1965 had a wingspan of , the official record for a living bird. The term wingspan, more technically 'extent' , is also used for other winged animals such as pterosaurs, bats, insects, etc., and other aircraft such as ornithopters. In humans, the term wingspan also refers to the arm span, which is the distance between the length from the end of an individual's arm (measured at the fingertips) to the individual's fingertips on the other arm when raised parallel to the ground at shoulder height. Wingspan of aircraft The wingspan of an aircraft is always measured in a straight line, from wingtip to wingtip, regardless of wing shape or sweep. Implications for aircraft design and animal evolution The lift from wings is proportional to their area, so the h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mainstream Media
In journalism, mainstream media (MSM) is a term and abbreviation used to refer collectively to the various large Mass media, mass news media that influence many people and both reflect and shape prevailing currents of thought.Noam Chomsky, Chomsky, Noam, ''"What makes mainstream media mainstream"'', October 1997, ''Z Magazine''/ref> The term is used to contrast with alternative media. The term is often used for large Media conglomerate, news conglomerates, including newspapers and broadcast media, that underwent successive mergers in many countries. The concentration of media ownership has raised concerns of a homogenization of viewpoints presented to news consumers. Consequently, the term ''mainstream media'' has been used in conversation and the blogosphere, sometimes in oppositional, pejorative or dismissive senses, in discussion of the mass media and media bias.

Aedeagus
An aedeagus ( or aedeagi) is a reproductive organ of male arthropods through which they secrete sperm from the testes during copulation (zoology), copulation with a female. It can be thought of as the insect equivalent of a mammal's penis, though the comparison is fairly loose given the greater complexity of insect reproduction. The term is derived . The aedeagus is part of the male's abdomen, which is the hindmost of the three major body sections of an insect. The pair of testes of the insect are connected to the aedeagus through the genital Duct (anatomy), ducts. The aedeagus is part of the male insect's phallus, a complex and often species-specific arrangement of more or less sclerotized (hardened) flaps and hooks which also includes in some species the valvae (clasper), which are paired organs which help the male hold on to the female during copulation. During copulation, the aedeagus connects with the ovipore of a female. The aedeagus can be quite pronounced or ''de minim ...

Clypeus (arthropod Anatomy)
The clypeus is one of the sclerites that make up the face of an arthropod. In insects, the clypeus delimits the lower margin of the face, with the labrum articulated along the ventral margin of the clypeus. The mandibles bracket the labrum, but do not touch the clypeus. The dorsal margin of the clypeus is below the antennal sockets. The clypeus is often well-defined by sulci ("grooves") along its lateral and dorsal margins, and is most commonly rectangular or trapezoidal in overall shape. The post-clypeus is a large nose-like structure that lies between the eyes and makes up much of the front of the head in cicadas. In spider Spiders (order (biology), order Araneae) are air-breathing arthropods that have eight limbs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude spider silk, silk. They are the largest order of arachnids and ran ...s, the clypeus is generally the area between the anterior edge of the carapace and the anterior eyes ...

Vespa Soror
''Vespa soror'', also known as the southern giant hornet, is a species of hornet present in India, Northern Thailand, Laos, Northern Vietnam, and parts of South China, including Hong Kong, Guangdong, Fujian, and Hainan Island. ''V. soror'' is one of the largest hornets, though smaller than the Asian giant hornet (''V. mandarinia''). The body lengths of the workers range from 26–35 mm, and those of queens range from 39–46 mm. Their nests are typically subterranean and found in forested areas. They are aggressive predators and have been observed to attack the nests of honeybees, wasps, and smaller hornet species. They also prey on mantids, dragonflies, butterflies, grasshoppers, and small vertebrates such as geckos. Predation on honeybees ''V. soror'' frequently attack bee colonies in groups, landing at and chewing on entrances, mass slaughtering adult defenders, and carrying away the carcasses and brood, which can destroy a colony. They exhibit behavior of rubbing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apical (anatomy)
Standard anatomical terms of location are used to describe unambiguously the anatomy of humans and other animals. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and axes. The meaning of terms that are used can change depending on whether a vertebrate is a biped or a quadruped, due to the difference in the neuraxis, or if an invertebrate is a non-bilaterian. A non-bilaterian has no anterior or posterior surface for example but can still have a descriptor used such as proximal or distal in relation to a body part that is nearest to, or furthest from its middle. International organisations have determined vocabularies that are often used as standards for subdisciplines of anatomy. For example, '' Terminolog ...

Vespa Tropica
''Vespa tropica'', the greater banded hornet, is a tropical species of hornet found in Southern Asia, New Guinea and west Africa, and which has recently been discovered to be an invasive species on the Pacific island of Guam. It is a predator of paper wasps and possesses a potent Stinger, sting, which can cause extreme pain and swelling. Description The Eusociality, workers of ''Vespa tropica'' are about in length, while queens grow to . The head is dark brown/red; the abdomen is black with a distinct yellow stripe which covers most of the second abdominal segment. However, there is some variation across its range and in Singapore and southeastern Asia, specimens are often completely black and larger in size, while in other regions such as Hong Kong, the head and flanks of the thorax are normally reddish. A third colour form is found in the Andaman Islands, Andamans and Nicobar Islands, Nicobars, which has a reddish brown head and thorax and all the dorsal plates on each segment ...
