Paul Allen's Flower Fly
Paul Allen's flower fly (''Eristalis alleni'') is a flower fly found only in Costa Rican forest in the central highlands. It was named after Paul Allen. Another fly was also named after Allen's associate Bill Gates, Bill Gates' flower fly (''Eristalis gatesi''). It is similar in appearance to ''Eristalis circe'' Williston, 1891 and ''Eristalis persa'' Williston, 1891, but has different leg colouration. Biology Little is known of its biology, but most adults are found in association with flowers in the genus ''Senecio ''Senecio'' is a genus of flowering plants in the daisy family (Asteraceae) that includes ragworts and groundsels.

Hoverfly
Hover flies, also called flower flies or syrphid flies, make up the insect family Syrphidae. As their common name suggests, they are often seen hovering or nectaring at flowers; the adults of many species feed mainly on nectar and pollen, while the larvae (maggots) eat a wide range of foods. In some species, the larvae are saprotrophs, eating decaying plant and animal matter in the soil or in ponds and streams. In other species, the larvae are insectivores and prey on aphids, thrips, and other plant-sucking insects. Insects such as aphids are considered a crop pest, and therefore the aphid-eating larvae of some hover flies serve as an economically (as well as ecologically) important predator and even potential agents for use in biological control, while the adults may be pollinators. About 6,000 species in 200 genera have been described. Hover flies are common throughout the world and can be found on all continents except Antarctica. Hover flies are harmless to most mammals, ...

Paul Allen
Paul Gardner Allen (January 21, 1953 – October 15, 2018) was an American business magnate, computer programmer, researcher, investor, and philanthropist. He co-founded Microsoft Corporation with childhood friend Bill Gates in 1975, which helped spark the microcomputer revolution of the 1970s and 1980s. Microsoft became the world's largest personal computer software company. Allen was ranked as the 44th-wealthiest person in the world by ''Forbes'' in 2018, with an estimated net worth of $20.3 billion at the time of his death. Allen left regular work at Microsoft in early 1983 after a Hodgkin lymphoma diagnosis, remaining on its board as vice-chairman. He and his sister, Jody Allen, founded Vulcan Inc. in 1986, a privately held company that managed his business and philanthropic efforts. He had a multi-billion dollar investment portfolio, including technology and media companies, scientific research, real estate holdings, private space flight ventures, and stakes in other se ...

Bill Gates
William Henry Gates III (born October 28, 1955) is an American business magnate and philanthropist. He is a co-founder of Microsoft, along with his late childhood friend Paul Allen. During his career at Microsoft, Gates held the positions of chairman, chief executive officer (CEO), President (corporate title), president and software architect, chief software architect, while also being the largest individual shareholder until May 2014. He was a major entrepreneur of the Home computer, microcomputer revolution of the 1970s and 1980s. Gates was born and raised in Seattle. In 1975, he and Allen founded Microsoft in Albuquerque, New Mexico. It became the world's largest personal computer software company. Gates led the company as chairman and CEO until stepping down as CEO in January 2000, succeeded by Steve Ballmer, but he remained chairman of the board of directors and became chief software architect. During the late 1990s, he was Criticism of Microsoft, criticized for his bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bill Gates' Flower Fly
Bill Gates' flower fly (''Eristalis gatesi'') is a flower fly endemic to Costa Rica named after Bill Gates. Another fly found in similar habitats was named after Gates' associate Paul Allen, called Paul Allen's flower fly (''Eristalis alleni''); according to Chris Thompson, the describer of these species, both names were in "recognition of heir Inheritance is the practice of receiving private property, titles, debts, entitlements, privileges, rights, and obligations upon the death of an individual.

Eristalis Circe
''Eristalis'' is a large genus of hoverflies, family Syrphidae, in the order Diptera. Several species are known as drone flies (or droneflies) because they bear a resemblance to honeybee drones. Drone flies and their relatives are fairly common generalist pollinators, the larvae of which are aquatic, and breathe through a long, snorkel-like appendage, hence the common name rat-tailed maggots. ''Eristalis'' is a large genus of around 99 species, and is subdivided into several subgenera and species groups (''Eristalomyia'', ''Eristalis'', ''Eoseristalis'' etc.). Scientific name and grammatical gender The scientific name was proposed by Pierre André Latreille in 1804. He placed seven species in his new genus, but listed the names as combinations with '' Syrphus'', so it remained unclear what gender he attributed to the name (the gender of the name ''Syrphus'' is masculine). In the two centuries following its publication, ''Eristalis'' was sometimes considered to be of femini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Senecio
''Senecio'' is a genus of flowering plants in the daisy family (Asteraceae) that includes ragworts and groundsels. Variously circumscribed taxonomically, the genus ''Senecio'' is one of the largest genera of flowering plants. Description Morphology The flower heads are normally rayed with the heads borne in branched clusters, and usually completely yellow, but green, purple, white and blue flowers are known as well. In its current circumscription, the genus contains species that are annual or perennial herbs, shrubs, small trees, aquatics or climbers. The only species which are trees are the species formerly belonging to '' Robinsonia'' occurring on the Juan Fernández Islands. Chemistry Pyrrolizidine alkaloids are found in all ''Senecio'' species. These alkaloids serve as a natural biocides to deter or even kill animals that would eat them. Livestock generally do not find them palatable. ''Senecio'' species are used as food plants by the larvae of some Lepidoptera species t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eristalinae
Eristalinae (or Milesiinae) are one of the four subfamilies of the fly family Syrphidae, or hoverflies. A well-known species included in this subfamily is the dronefly, ''Eristalis tenax''. Species in this subfamily are often misclassified as bees instead of flies due to their exceptional Mimicry, especially to resemble Honeybees (family Apidae). The best strategy for proper identification is to look at their eyes and wings and compare with fly morphology, to determine membership of family Syrphidae and/or of order Hymenoptera. Taxonomy This subfamily consists of the following tribes: * Brachyopini * Callicerini * Cerioidini * Eristalini * Sericomyiini * Eumerini * Milesiini * Pipizini * Rhingiini * Spheginobacchini * Volucellini gallery Brachyopa daeckei.jpg, ''Brachyopa daeckei'' actual size Sphiximorpha subsessilis, Parc de Woluwé, Brussels (34851582946).jpg, ''Sphiximorpha subsessilis'' Namaste!

Insects Described In 1997
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. Insect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
