Leucauge Celebesiana
''Leucauge celebesiana'', commonly called the black-striped orchard spider, is a species of spider belonging to the family Tetragnathidae. It is found from India to China, Japan, Sulawesi and New Guinea. Like many of its congeners, this is a colourful and distinctive spider. It has a body length (excluding legs) of . The abdomen is white with yellow-green sides with black stripes separating the white from the coloured flanks. Another black stripe runs right down the middle. This species constructs a web inclined at 45° and several individuals often build these webs close together.

Baron Charles Athanase Walckenaer (25 December 1771 – 28 April 1852) was a French civil servant and scientist. Biography Walckenaer was born in Paris and studied at the universities of University of Oxford, Oxford and University of Glasgow, Glasgow. In 1793 he was appointed head of the military transports in the Pyrenees, after which he pursued technical studies at the École Nationale des Ponts et Chaussées and the École polytechnique.

Spider
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had ...

Tetragnathidae
Long-jawed orb weavers or long jawed spiders (Tetragnathidae) are a family of araneomorph spiders first described by Anton Menge in 1866. They have elongated bodies, legs, and chelicerae, and build small orb webs with an open hub with few, wide-set radii and spirals with no signal line or retreat. Some species are often found in long vegetation near water. Systematics , the World Spider Catalog accepts the following extant genera: *''Alcimosphenus'' Simon, 1895 — Caribbean *'' Allende'' Álvarez-Padilla, 2007 — Chile, Argentina *'' Antillognatha'' Bryant, 1945 — Hispaniola *'' Atelidea'' Simon, 1895 — Sri Lanka *'' Azilia'' Keyserling, 1881 — United States, Panama, South America, Caribbean *''Chrysometa'' Simon, 1894 — South America, Central America, Mexico, Caribbean *''Cyrtognatha'' Keyserling, 1881 — South America, Central America, Caribbean, Mexico *'' Dianleucauge'' Song & Zhu, 1994 — China *'' Diphya'' Nicolet, 1849 — Asia, South America, Africa *''Dolic ...

Sulawesi
Sulawesi (), also known as Celebes (), is an island in Indonesia. One of the four Greater Sunda Islands, and the world's eleventh-largest island, it is situated east of Borneo, west of the Maluku Islands, and south of Mindanao and the Sulu Archipelago. Within Indonesia, only Sumatra, Borneo, and New Guinea, Papua are larger in territory, and only Java and Sumatra have larger populations. The landmass of Sulawesi includes four peninsulas: the northern Minahassa Peninsula, Minahasa Peninsula, the East Peninsula, Sulawesi, East Peninsula, the South Peninsula, Sulawesi, South Peninsula, and the Southeast Peninsula, Sulawesi, Southeast Peninsula. Three gulfs separate these peninsulas: the Gulf of Tomini between the northern Minahasa and East peninsulas, the Tolo Gulf between the East and Southeast peninsulas, and the Bone Gulf between the South and Southeast peninsulas. The Strait of Makassar runs along the western side of the island and separates the island from Borneo. Etymology ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Conspecificity
Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organisms or constituents of living organisms of being special or doing something special. Each animal or plant species is special. It differs in some way from all other species...biological specificity is the major problem about understanding life." Biological specificity within ''Homo sapiens'' ''Homo sapiens'' has many characteristics that show the biological specificity in the form of behavior and morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other hominins. The reduction of dentition is a feature that allows for the advantage of adaptability in diet and survival. As a species, humans are culture dependent and much of human survival relies on the culture and soci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abdomen
The abdomen (colloquially called the belly, tummy, midriff, tucky or stomach) is the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. The abdomen is the front part of the abdominal segment of the torso. The area occupied by the abdomen is called the abdominal cavity. In arthropods it is the posterior (anatomy), posterior tagma (biology), tagma of the body; it follows the thorax or cephalothorax. In humans, the abdomen stretches from the thorax at the thoracic diaphragm to the pelvis at the pelvic brim. The pelvic brim stretches from the lumbosacral joint (the intervertebral disc between Lumbar vertebrae, L5 and Vertebra#Sacrum, S1) to the pubic symphysis and is the edge of the pelvic inlet. The space above this inlet and under the thoracic diaphragm is termed the abdominal cavity. The boundary of the abdominal cavity is the abdominal wall in the front and the peritoneal surface at the rear. In vertebrates, the abdomen is a large body c ...

Spider Web
A spider web, spiderweb, spider's web, or cobweb (from the archaic word '' coppe'', meaning "spider") is a structure created by a spider out of proteinaceous spider silk extruded from its spinnerets, generally meant to catch its prey. Spider webs have existed for at least 100 million years, as witnessed in a rare find of Early Cretaceous amber from Sussex, in southern England. Many spiders build webs specifically to trap and catch insects to eat. However, not all spiders catch their prey in webs, and some do not build webs at all. "Spider web" is typically used to refer to a web that is apparently still in use (i.e. clean), whereas "cobweb" refers to abandoned (i.e. dusty) webs. However, the word "cobweb" is also used by biologists to describe the tangled three-dimensional web of some spiders of the family Theridiidae. While this large family is known as the cobweb spiders, they actually have a huge range of web architectures; other names for this spider family include tangl ...

Leucauge
''Leucauge'' () is a spider genus of long-jawed orb weavers, with over 160 species and fully pantropical distribution. The genus was first documented in Scottish zoologist Adam White's 1841 ''Description of new or little known Arachnida''. Charles Darwin had suggested the name of the genus and collected the first specimen in May 1832, later named ''L. argyrobapta''. A vague description and the loss of the only specimen left the genus ill-defined. ''Leucauge'' developed into something of a wastebasket taxon containing 300 loosely related species, until research in the year 2010 resolved ''L. argyrobapta'' as a synonym of the quite common '' L. venusta'' and allowed revision and reclassing of the genus. However, a 2018 paper restored ''Leucauge argyrobapta'' as a separate species. The body and leg shapes and the silver, black and yellow markings of ''Leucauge'' females make identification of the genus relatively easy. They have two rows of long, slender curved hairs on the femu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
