Vespa Bicolor
''Vespa bicolor'', the black shield wasp, described by Johan Christian Fabricius in 1787, is a species of hornet which has been found to be the pollinator of an orchid, ''Dendrobium sinense'' (syn. ''Dendrobium christyanum''), found only on the Chinese island of Hainan. ''Vespa bicolor'' also preys on honey bees, which it feeds to its larvae. The orchid produces a chemical that mimics a honey bee pheromone and attracts this predatory wasp. ''Vespa bicolor'' is the most common species of large wasp in Hong Kong Hong Kong ( (US) or (UK); , ), officially the Hong Kong Special Administrative Region of the People's Republic of China ( abbr. Hong Kong SAR or HKSAR), is a city and special administrative region of China on the eastern Pearl River Delt ..., along with members of the genus '' Parapolybia''. It is found in a wide range of environments and can be found near human dwellings. References Vespidae Insects described in 1787 Hymenoptera of Asia {{Vespidae- ...

Johan Christian Fabricius
Johan Christian Fabricius (7 January 1745 – 3 March 1808) was a Danish zoologist, specialising in "Insecta", which at that time included all arthropods: insects, arachnids, crustaceans and others. He was a student of Carl Linnaeus, and is considered one of the most important entomologists of the 18th century, having named nearly 10,000 species of animals, and established the basis for the modern insect classification. Biography Johan Christian Fabricius was born on 7 January 1745 at Tønder in the Duchy of Schleswig, where his father was a doctor. He studied at the gymnasium at Altona and entered the University of Copenhagen in 1762. Later the same year he travelled together with his friend and relative Johan Zoëga to Uppsala, where he studied under Carl Linnaeus for two years. On his return, he started work on his , which was finally published in 1775. Throughout this time, he remained dependent on subsidies from his father, who worked as a consultant at Frederiks Hospita ...

Hornet
Hornets (insects in the genus ''Vespa'') are the largest of the eusocial wasps, and are similar in appearance to their close relatives yellowjackets. Some species can reach up to in length. They are distinguished from other vespine wasps by the relatively large top margin of the head. Worldwide, 22 species of ''Vespa'' are recognized.A.H. Smith-Pardo, J.M. Carpenter, L.

Insect Systematics and Diversity 4(3) https://doi.org/10.1093/isd/ixaa006 Most species only occur in the tropics of Asia, though the European hornet (''V. crabro''), is widely distributed throughout Europe, Russia, North America, and north-eastern Asia. Wasps native to North America in the genus '' Dolichovespula'' are commonly referred to as hornets (e.g., baldfaced hornets), but are actually yellowjackets. Like other social wasps, hornets build communal n ...

Pollinator
A pollinator is an animal that moves pollen from the male anther of a flower to the female stigma of a flower. This helps to bring about fertilization of the ovules in the flower by the male gametes from the pollen grains. Insects are the major pollinators of most plants, and insect pollinators include all families of bees and most families of aculeate wasps; ants; many families of flies; many lepidopterans (both butterflies and moths); and many families of beetles. Vertebrates, mainly bats and birds, but also some non-bat mammals (monkeys, lemurs, possums, rodents) and some lizards pollinate certain plants. Among the pollinating birds are hummingbirds, honeyeaters and sunbirds with long beaks; they pollinate a number of deep-throated flowers. Humans may also carry out artificial pollination. A pollinator is different from a pollenizer, a plant that is a source of pollen for the pollination process. Background Plants fall into pollination syndromes that reflect the type o ...

Orchid
Orchids are plants that belong to the family Orchidaceae (), a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Along with the Asteraceae, they are one of the two largest families of flowering plants. The Orchidaceae have about 28,000 currently accepted species, distributed in about 763 genera. (See ''External links'' below). The determination of which family is larger is still under debate, because verified data on the members of such enormous families are continually in flux. Regardless, the number of orchid species is nearly equal to the number of bony fishes, more than twice the number of bird species, and about four times the number of mammal species. The family encompasses about 6–11% of all species of seed plants. The largest genera are ''Bulbophyllum'' (2,000 species), ''Epidendrum'' (1,500 species), ''Dendrobium'' (1,400 species) and ''Pleurothallis'' (1,000 species). It also includes ''Vanilla'' (the genus of the ...

Dendrobium Christyanum
''Dendrobium christyanum'' is a species of orchid (Orchidaceae) endemic to the Chinese island of Hainan. It produces a volatile organic compound that is unrecorded in other plant species. The flowers of this orchid produce a bee pheromone which attracts its pollinator, '' Vespa bicolor'', a species of hornet. The novel feature, first reported in 2009, is supposed to mimic the distress pheromone of the indigenous Asian honey bee ''Apis cerana'' (the same chemical as in the European ''Apis mellifera'', which does not occur naturally on Hainan). The chemical compound, (Z)-11-eicosen-1-ol, can be detected by the hornet and is it is assumed this mimicry deceives the insect into visiting the flower without reward (the flowers offer no nectar). ''V. bicolor'' preys on honey bees to feed its larvae. The European beewolf (''Philanthus triangulum The European beewolf (''Philanthus triangulum''), also known as the bee-killer wasp or the bee-eating philanthus (from the now obsolete syno ...

Hainan (, ; ) is the smallest and southernmost province of the People's Republic of China (PRC), consisting of various islands in the South China Sea. , the largest and most populous island in China,The island of Taiwan, which is slightly larger, is claimed but not controlled by the PRC. It is instead controlled by the Republic of China, a ''de facto'' separate country. makes up the vast majority (97%) of the province. The name means "south of the sea", reflecting the island's position south of the Qiongzhou Strait, which separates it from Leizhou Peninsula. The province has a land area of , of which Hainan the island is and the rest is over 200 islands scattered across three archipelagos: Zhongsha, Xisha and Nansha. It was part of Guangdong from 1950–88, after which it resumed as a top-tier entity and almost immediately made the largest Special Economic Zone by Deng Xiaoping as part of the then-ongoing Chinese economic reform program.

Honey Bee
A honey bee (also spelled honeybee) is a eusocial flying insect within the genus ''Apis'' of the bee clade, all native to Afro-Eurasia. After bees spread naturally throughout Africa and Eurasia, humans became responsible for the current cosmopolitan distribution of honey bees, introducing multiple subspecies into South America (early 16th century), North America (early 17th century), and Australia (early 19th century). Honey bees are known for their construction of perennial colonial nests from wax, the large size of their colonies, and surplus production and storage of honey, distinguishing their hives as a prized foraging target of many animals, including honey badgers, bears and human hunter-gatherers. Only eight surviving species of honey bee are recognized, with a total of 43 subspecies, though historically 7 to 11 species are recognized. Honey bees represent only a small fraction of the roughly 20,000 known species of bees. The best known honey bee is the weste ...

Hong Kong
Hong Kong ( (US) or (UK); , ), officially the Hong Kong Special Administrative Region of the People's Republic of China ( abbr. Hong Kong SAR or HKSAR), is a city and special administrative region of China on the eastern Pearl River Delta in South China. With 7.5 million residents of various nationalities in a territory, Hong Kong is one of the most densely populated places in the world. Hong Kong is also a major global financial centre and one of the most developed cities in the world. Hong Kong was established as a colony of the British Empire after the Qing Empire ceded Hong Kong Island from Xin'an County at the end of the First Opium War in 1841 then again in 1842.. The colony expanded to the Kowloon Peninsula in 1860 after the Second Opium War and was further extended when Britain obtained a 99-year lease of the New Territories in 1898... British Hong Kong was occupied by Imperial Japan from 1941 to 1945 during World War II; British administration resume ...

Vespidae
The Vespidae are a large (nearly 5000 species), diverse, cosmopolitan family of wasps, including nearly all the known eusocial wasps (such as ''Polistes fuscatus'', ''Vespa orientalis'', and ''Vespula germanica'') and many solitary wasps. Each social wasp colony includes a queen and a number of female workers with varying degrees of sterility relative to the queen. In temperate social species, colonies usually last only one year, dying at the onset of winter. New queens and males (drones) are produced towards the end of the summer, and after mating, the queens hibernate over winter in cracks or other sheltered locations. The nests of most species are constructed out of mud, but polistines and vespines use plant fibers, chewed to form a sort of paper (also true of some stenogastrines). Many species are pollen vectors contributing to the pollination of several plants, being potential or even effective pollinators, while others are notable predators of pest insect species. The sub ...

Insects Described In 1787
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. ...
