Formica Cinerea
''Formica cinerea'' is a species of ant in the family Formicidae. Distribution This species is distributed through the majority of Europe, from Spain to western Siberia and from Scandinavia to the Balkans. Its also present in the Near East and in the eastern Palearctic realm. It is lacking in the UK. Description ''Formica cinerea'' can reach a length of in workers, or in queens. Body is dark gray or silvery, large and agile, with extra large eyes and dark reddish legs. This species can be easily confused with ''Formica fusca'', '' Formica fuscocinerea'' and ''Formica selysi''. The distinction of these species is very difficult and it is only possible under the microscope. Habitat Underground nest are usually built in dry and sunny sand habitats with scarce vegetation. It is often found together with the ant ''Lasius psammophilus'' on sand-dunes. Also occurs in human-constructed open habitats such as river dams, on seaside beaches and occurs up to 1800–2500 m in the mountai ...

He specialised in Hymenoptera, being particularly known for his studies of ants.1908. Obituary. Prof. Gustav Mayr. Entomological News 19:396 Bibliography In 1868, he was the first to describe the Argentine ant. He is credited with naming the species, ''Aphaenogaster treatae'', for naturalist Mary Davis Treat, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Near East
The ''Near East''; he, המזרח הקרוב; arc, ܕܢܚܐ ܩܪܒ; fa, خاور نزدیک, Xāvar-e nazdik; tr, Yakın Doğu is a geographical term which roughly encompasses a transcontinental region in Western Asia, that was once the historical Fertile Crescent, and later the Levant region. It also comprises Turkey (both Anatolia and East Thrace) and Egypt (mostly located in North Africa, with the Sinai Peninsula being in Asia). Despite having varying definitions within different academic circles, the term was originally applied to the maximum extent of the Ottoman Empire. According to the National Geographic Society, the terms ''Near East'' and ''Middle East'' denote the same territories and are "generally accepted as comprising the countries of the Arabian Peninsula, Cyprus, Egypt, Iraq, Iran, Israel, Jordan, Lebanon, Palestinian territories, Syria, and Turkey". In 1997, the Food and Agriculture Organization of the United Nations, Food and Agriculture Organization (FAO) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palearctic Realm
The Palearctic or Palaearctic is the largest of the eight biogeographic realms of the Earth. It stretches across all of Eurasia north of the foothills of the Himalayas, and North Africa. The realm consists of several bioregions: the Euro-Siberian region; the Mediterranean Basin; the Sahara and Arabian Deserts; and Western, Central and East Asia. The Palaearctic realm also has numerous rivers and lakes, forming several freshwater ecoregions. The term 'Palearctic' was first used in the 19th century, and is still in use as the basis for zoogeographic classification. History In an 1858 paper for the ''Proceedings of the Linnean Society'', British zoologist Philip Sclater first identified six terrestrial zoogeographic realms of the world: Palaearctic, Aethiopian/ Afrotropic, Indian/ Indomalayan, Australasian, Nearctic, and Neotropical. The six indicated general groupings of fauna, based on shared biogeography and large-scale geographic barriers to migration. Alfred ...

Formica Fusca
''Formica fusca'' is a black-colored ant commonly found throughout Europe as well as parts of Southern Asia and Africa. It has the common names silky ant or dusky ant. The range within the palaearctic region extends from Portugal in the west to Japan in the east and from Italy in the south to Fennoscandia in the north. Populations from North America have been split off as a separate species, '' Formica subaenescens''. ''F. fusca'' nests are usually found in rotten tree stumps or under stones in clearcut areas and along woodland borders and hedgerows. Eusociality Colonies are facultatively polygynous (though weakly so); though the queens coexist amicably, contribution to the brood tends to be unequal. Nests are usually small, containing 500–2,000 workers. The workers are large, at long, and fast moving, though timid. To ensure that non-nest mate eggs are not reared, these workers will engage in a process known as worker policing. Alate (winged) forms are produced in June ...

Formica Fuscocinerea
''Formica'' is a genus of ants of the family Formicidae, commonly known as wood ants, mound ants, thatching ants, and field ants. ''Formica'' is the type genus of the Formicidae, and of the subfamily Formicinae. The type species of genus ''Formica'' is the European red wood ant ''Formica rufa''. Ants of this genus tend to be between 4 and 8 mm long. Habitat As the name wood ant implies, many ''Formica'' species live in wooded areas where no shortage of material exists with which they can thatch their mounds (often called anthills). One shade-tolerant species is '' F. lugubris''. However, sunlight is important to most ''Formica'' species, and colonies rarely survive for any considerable period in deeply shaded, dense woodland. The majority of species, especially outside the ''F. rufa'' species group, are inhabitants of more open woodlands or treeless grassland or shrubland. In North America, at least, these habitats had a long history of frequent landscape-scale fires t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Honeydew (secretion)
Honeydew is a sugar-rich sticky liquid, secreted by aphids and some scale insects as they feed on plant sap. When their mouthpart penetrates the phloem, the sugary, high-pressure liquid is forced out of the anus of the aphid. Honeydew is particularly common as a secretion in hemipteran insects and is often the basis for trophobiosis. Some caterpillars of Lycaenidae butterflies and some moths also produce honeydew. Honeydew producing insects, like cicadas, pierce phloem ducts to access the sugar rich sap. The sap continues to bleed after the insects have moved on, leaving a white sugar crust called manna. Ants may collect, or "milk", honeydew directly from aphids and other honeydew producers, which benefit from their presence due to their driving away predators such as lady beetles or parasitic wasps—see ''Crematogaster peringueyi''. Animals and plants in a mutually symbiotic arrangement with ants are called Myrmecophiles. In Madagascar, some gecko species in the genera ''Phe ...

Monogyne
The gyne (, from Greek γυνή, "woman") is the primary reproductive female caste of social insects (especially ants, wasps, and bees of order Hymenoptera, as well as termites). Gynes are those destined to become queens, whereas female workers are typically barren and cannot become queens. Having a queen is what makes a "queenright" hive, nest, or colony of eusocial insects. A colony with multiple queens is said to be a polygyne form, whereas one with only one is a monogyne form. The red imported fire ant is known to have colonies in both polygyne and monogyne forms. The small red ant, ''Leptothorax acervorum'', has colonies that switch from monogyny to polygyny as a result of seasonal fluctuations. The little fire ant ''Wasmannia auropunctata'' produces unique kinds of meiotic oocytes with a drastic reduction in recombination. These oocytes may either fuse together for gyne production ( automictic parthenogenesis with central fusion) or be fertilized by male gametes for the ...

Hymenoptera Of Europe
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism (complete metamorphosis)—that is, they have a wormlike larval stage and an inactive pupal stage before they mature. Etymology The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous. All references agree that the derivation involves the Ancient Greek πτερόν (''pteron'') for wing. The Ancient Greek ὑμήν (''hymen'') for membrane provides a plausible etymology for the term because species in this order have membranous wings. However, a key characteristic of this order is that the hindwings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
