Belgica Antarctica
''Belgica antarctica'', the Antarctic midge, is a species of flightless midge, endemic to the continent of Antarctica. At long, it is the largest purely terrestrial animal native to the continent. It also has the smallest known insect genome as of 2014, with only 99 million base pairs of nucleotides and about genes. It is the only insect that can survive year-round in Antarctica. Tolerance to extreme conditions The flightlessness of ''B. antarctica'' may be an adaptation to prevent wind from blowing it into inhospitable areas. It can survive freezing, but though local air temperatures may reach as low as −40 °C, this insect cannot survive temperatures below −15 °C. This is comparatively milder than other cold-adapted insects. The reason for this relatively low freezing tolerance is due to thermal buffering: just burrowing at a depth of 1 cm, temperature is stable between 0 and −2 °C for 10 months out of 12, and it seldom goes lower than −7 °C ...

Jean-Charles Jacobs
Jean-Charles Jacobs (1821 – 1907) was a Belgian doctor and entomologist, a pupil of Constantin Wesmael. He graduated in medicine from the University of Brussels, but never abandoned the study of insects, and was one of the founders of the ''Société entomologique de Belgique''. He concentrated on the Hymenoptera, often in collaboration with Jules Tosquinet, turning to Diptera later in life. Among his later studies was a report on the insects collected by the Belgian Antarctic Expedition, including that continent's largest fully terrestrial animal, the fly ''Belgica antarctica ''Belgica antarctica'', the Antarctic midge, is a species of flightless midge, endemic to the continent of Antarctica.

Eugène Séguy
Eugene Séguy (21 April 1890 – 1 June 1985) was a French entomologist and artist who specialised in Diptera. He held a chair of entomology at the Muséum national d'histoire naturelle in Paris from 1956 to 1960. He is also known for establishing the Diptera section at that museum. This entomologist is often confused with a French artist with a similar name: Émile-Allain Séguy (1877–1951). The latter is known for his pochoir artworks representing plants and insects.

Midge
A midge is any small fly, including species in several families of non-mosquito Nematoceran Diptera. Midges are found (seasonally or otherwise) on practically every land area outside permanently arid deserts and the frigid zones. Some midges, such as many Phlebotominae (sand fly) and Simuliidae (black fly), are vectors of various diseases. Many others play useful roles as prey for insectivores, such as various frogs and swallows. Others are important as detritivores, and form part of various nutrient cycles. The habits of midges vary greatly from species to species, though within any particular family, midges commonly have similar ecological roles. Examples of families that include species of midges include: * Blephariceridae, net-winged midges * Cecidomyiidae, gall midges * Ceratopogonidae, biting midges (also known as no-see-ums or punkies in North Americabr>BugGuide/ref> and sandflies in Australia) * Chaoboridae, phantom midges * Chironomidae, non-biting midges (a ...

Chironomidae
The Chironomidae (informally known as chironomids, nonbiting midges, or lake flies) comprise a family of nematoceran flies with a global distribution. They are closely related to the Ceratopogonidae, Simuliidae, and Thaumaleidae. Many species superficially resemble mosquitoes, but they lack the wing scales and elongated mouthparts of the Culicidae. The name Chironomidae stems from the Ancient Greek word ''kheironómos'', "a pantomimist". Common names and biodiversity This is a large taxon of insects; some estimates of the species numbers suggest well over 10,000 world-wide. Males are easily recognized by their plumose antennae. Adults are known by a variety of vague and inconsistent common names, largely by confusion with other insects. For example, chironomids are known as "lake flies" in parts of Canada and Lake Winnebago, Wisconsin, but "bay flies" in the areas near the bay of Green Bay, Wisconsin. They are called "sand flies", "muckleheads", "muffleheads", "Canadian so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crozet Islands
The Crozet Islands (french: Îles Crozet; or, officially, ''Archipel Crozet'') are a sub-Antarctic archipelago of small islands in the southern Indian Ocean. They form one of the five administrative districts of the French Southern and Antarctic Lands. History Discovery and early history The Crozet Islands were discovered on 24 January 1772, by the expedition of French explorer Marc-Joseph Marion du Fresne, aboard ''Le Mascarin''. His second-in-command Jules (Julien-Marie) Crozet landed on Île de la Possession, claiming the archipelago for France. The expedition continued east and landed in New Zealand, where Captain Marion and much of his crew were killed and cannibalized by Maori. Crozet survived the disaster, and successfully led the survivors back to their base in Mauritius. In 1776, Crozet met James Cook at Cape Town, at the start of Cook's third voyage. Crozet shared the charts of his ill-fated expedition, and as Cook sailed eastward, he stopped at the islands, naming ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Belgica
Gallia Belgica ("Belgic Gaul") was a Roman province, province of the Roman Empire located in the north-eastern part of Roman Gaul, in what is today primarily northern France, Belgium, and Luxembourg, along with parts of the Netherlands and Germany. In 50 BC, after the conquest by Julius Caesar during his Gallic Wars, it became one of the three parts of Gaul (Tres Galliae), the other two being Gallia Aquitania and Gallia Lugdunensis. An official Roman province was later created by emperor Augustus in 22 BC. The province was named for the Belgae, as the largest tribal confederation in the area, but also included the territories of the Treveri, Mediomatrici, Leuci, Sequani, Helvetii and others. The southern border of Belgica, formed by the Marne River, Marne and Seine rivers, was reported by Caesar as the original cultural boundary between the Belgae and the Celts, Celtic Gauls, whom he distinguished from one another. The province was re-organised several times, first increased and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insects Of Antarctica
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] |
