Paolo Magretti
Paolo Magretti (15 December 1854, Milan – 30 August 1913, Paderno Dugnano) was an Italian entomologist who specialized in Hymenoptera studies. He studied zoology under Leopoldo Maggi and Pietro Pavesi at the University of Pavia, graduating in 1880 with a thesis on Hymenoptera found in Lombardy.Treccani.it Dizionario Biografico / Paolo Magretti In 1883 he undertook a zoological expedition to eastern and , in which he collected a number of Hymenoptera species new to science.

Ritratto Di Paolo Magretti
A portrait is a painting, photograph, sculpture, or other artistic representation of a person, in which the face and its expressions are predominant. The intent is to display the likeness, personality, and even the mood of the person. For this reason, in photography a portrait is generally not a snapshot, but a composed image of a person in a still position. A portrait often shows a person looking directly at the painter or photographer, in order to most successfully engage the subject with the viewer. History Prehistorical portraiture Plastered human skulls were reconstructed human skulls that were made in the ancient Levant between 9000 and 6000 BC in the Pre-Pottery Neolithic B period. They represent some of the oldest forms of art in the Middle East and demonstrate that the prehistoric population took great care in burying their ancestors below their homes. The skulls denote some of the earliest sculptural examples of portraiture in the history of art. Historical portraitu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Milano–Torino
Milano–Torino is a semi classic European single day cycling race, between the northern Italian cities of Milan and Turin over a distance of 199 kilometres. The event was first run in 1876 making it the oldest classic race in the world. The event is owned by the RCS media group which owns the Italian sports daily ''La Gazzetta dello Sport''. RCS also organises other top Italian cycling events such as the Giro d'Italia, Milan–San Remo and Tirreno–Adriatico. The race is ranked UCI ProSeries on the UCI continental calendar. The race was not run between the spring of 2007 and the autumn of 2012. Race dates The position of the race in the European calendar has changed several times. Prior to 1987 the event was always seven days before Milan–San Remo and was seen as an important preparation race for the Spring Classics, however in 1987 Milano–Torino was switched to a date in October just before the Giro di Lombardia because the race organisers were not happy with the incle ...

Scientists From Milan
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''

Cyclists From Milan
Cycling, also, when on a two-wheeled bicycle, called bicycling or biking, is the use of cycles for transport, recreation, exercise or sport. People engaged in cycling are referred to as "cyclists", "bicyclists", or "bikers". Apart from two-wheeled bicycles, "cycling" also includes the riding of unicycles, tricycles, quadricycles, recumbent and similar human-powered vehicles (HPVs). Bicycles were introduced in the 19th century and now number approximately one billion worldwide. They are the principal means of transportation in many parts of the world, especially in densely populated European cities. Cycling is widely regarded as an effective and efficient mode of transportation optimal for short to moderate distances. Bicycles provide numerous possible benefits in comparison with motor vehicles, including the sustained physical exercise involved in cycling, easier parking, increased maneuverability, and access to roads, bike paths and rural trails. Cycling also offers a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tiphiidae
The Tiphiidae (also known as the tiphiid wasps) are a family of large, solitary wasps whose larvae are parasitoids of various beetle larvae, especially those in the superfamily Scarabaeoidea. Until recently, this family contained several additional subfamilies, but multiple studies have independently confirmed that these comprise a separate lineage, and are now classified in the family Thynnidae. The females of some Brachycistidinae are wingless, and hunt ground-dwelling ( fossorial) beetle larvae. The prey is paralysed with the female's sting, and an egg is lain on it so the wasp larva has a ready supply of food. As some of the ground-dwelling scarab species attacked by tiphiids are pests, some of these wasps are considered beneficial as biological control agents. Taxonomy Tiphiid genera are classified as follows: Subfamily Brachycistidinae *'' Acanthetropis'' Wasbauer, 1958 *'' Brachycistellus'' Baker, 1907 *'' Brachycistina'' Malloch, 1926 *'' Brachycistis'' Fox, 1 ...

Scoliidae
The Scoliidae, the scoliid wasps, are a family of about 560 species found worldwide. They tend to be black, often marked with yellow or orange, and their wing tips are distinctively corrugated. Males are more slender and elongated than females, with significantly longer antennae, but the sexual dimorphism is not as apparent as in the Tiphiidae. Biology Scoliid wasps are solitary parasitoids of scarab beetle larvae. Female scoliids burrow into the ground in search of these larvae and then use their sting to paralyze them. They will sometimes excavate a chamber and move the paralyzed beetle larva into it before depositing an egg. Scoliid wasps act as important biocontrol agents, as many of the beetles they parasitize are pests, including the Japanese beetle. Male scoliids patrol territories, ready to mate with females emerging from the ground. Adult wasps may be minor pollinators of some plants and can be found on many wildflowers in the late summer. Scoliidae also has at least ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mutillidae
The Mutillidae are a family of more than 7,000 species of wasps whose wingless females resemble large, hairy ants. Their common name velvet ant refers to their dense pile of hair, which most often is bright scarlet or orange, but may also be black, white, silver, or gold. Their bright colors serve as aposematic signals. They are known for their extremely painful stings, (the sting of the species ''Dasymutilla klugii'' rated a 3 on the Schmidt pain index and lasts up to 30 minutes), and has resulted in the common name "cow killer" or "cow ant" being applied to the species ''Dasymutilla occidentalis.'' However, mutillids are not aggressive and sting only in defense. In addition, the actual toxicity of their venom is much lower than that of honey bees or harvester ants. Unlike true ants, they are solitary, and lack complex social systems. Distribution Mutillidae can be found worldwide with about 230 genera or subgenera and around 8,000 species worldwide.
