Common Name
In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is Latinized. A common name is sometimes frequently used, but that is not always the case. In chemistry, IUPAC defines a common name as one that, although it unambiguously defines a chemical, does not follow the current systematic naming convention, such as acetone, systematically 2-propanone, while a vernacular name describes one used in a lab, trade or industry that does not unambiguously describe a single chemical, such as copper sulfate, which may refer to either copper(I) sulfate or copper(II) sulfate. Sometimes common names are created by authorities on one particular subject, in an attempt to make it possible for members of the general public (including such interested par ...

Araneidae
Orb-weaver spiders are members of the spider family Araneidae. They are the most common group of builders of spiral wheel-shaped webs often found in gardens, fields, and forests. The English word "orb" can mean "circular", hence the English name of the group. Araneids have eight similar eyes, hairy or spiny legs, and no stridulating organs. The family has a cosmopolitan distribution, including many well-known large or brightly colored garden spiders. With 3,108 species in 186 genera worldwide, the Araneidae comprise the third-largest family of spiders (behind the Salticidae and Linyphiidae). Araneid webs are constructed in a stereotypical fashion, where a framework of nonsticky silk is built up before the spider adds a final spiral of silk covered in sticky droplets. Orb webs are also produced by members of other spider families. The long-jawed orb weavers (Tetragnathidae) were formerly included in the Araneidae; they are closely related, being part of the superfamily Araneo ...

Araneus Gemmoides
''Araneus gemmoides'', commonly known as the jewel spider (a name shared with ''Austracantha minax'') and cat-faced spider (a name shared with ''Araneus gemma''), is a common, outdoor, orb-weaver spider found in Canada and the USA. It is considered harmless and has a low-toxicity venom. ''A. gemmoides'' is a useful natural predator for insects. ''A. gemmoides'' makes its webs near lights, closed spaces, and on the sides of buildings. It can also be found under wood, overhangs, or guarded places such as animal burrows. The species occurs in varying colors, but is easily identified by the two horn-shaped growths on its relatively large abdomen. Its color changes from summer to winter. The females die within days of laying a single egg sac with hundreds of eggs. Egg sacs can survive over winter, and the emerging spiderlings eat their siblings. The babies ride strands of silk in warm air currents, which are able to transport them to locations miles away. Females have a larg ...

Austracantha Minax
''Austracantha'' is a genus of spider with a single species, ''Austracantha minax'', commonly known as the jewel spider or the Christmas spider. It is a member of the family Araneidae (the orb-weavers) and is endemic to Australia. They are relatively small spiders, reaching a maximum total body length of only around for females, and for males. Their abdomen has six distinctive projections ("spines") that makes them easy to identify. They are predominantly a shiny black, with variable white, yellow, and orange patterns. Melanistic forms also occur during autumn. They are facultatively gregarious, and can be found in large aggregations of overlapping orb webs. They feed on small flying insects that get entangled in their webs. They are harmless to humans, though the webs can be a nuisance for bushwalkers. They are most abundant during the summer months. Taxonomy and nomenclature ''Austracantha minax'' is most commonly known as "jewel spiders" due to their body colouration. ...

Gasteracantha Cancriformis
''Gasteracantha cancriformis'' (spinybacked orbweaver) is a species of orb-weaver spider (family Araneidae). It is widely distributed in the New World. The genus name ''Gasteracantha'' derives from the Greek words (', "belly") and (', "thorn"), while the specific epithet ''cancriformis'' derives from the Latin words ' ("crab") and ' ("shape, form, appearance"). Description Females are long and wide. The six abdominal spine-like projections on the abdomen are characteristic. The carapace, legs, and underside are black with white spots under the abdomen. Variations occur in the colour of the upperside of the abdomen - a white or yellow colour with both featuring black spots. A white upper side can have either red or black spines while a yellow upperbside can only have black ones. Like with many other spiders, males are much smaller (2 to 3 mm long) and longer than wide. All morphs have six abdominal spines. They are similar to the females in colour, but have a gray abdo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gasteracantha Fornicata
''Gasteracantha fornicata'' (northern jewelled spider) is a species of spiny orb-weavers (family Araneidae) found in Queensland Australia. It is similar in shape to ''Austracantha minax'' which was originally described as ''Gasteracantha minax''. It was described by Johan Christian Fabricius in 1775, the first Australian species of spider to be named and classified. One of the synonyms of the species is ''Gasteracantha vittata'', a name given to it by Ludwig Carl Christian Koch in 1871. However, it was later discovered that Fabricius had described the species earlier, and according to taxonomic rules, the earlier name has precedence and is the only one that should be used. Also, there are other species that were identified ''G. vittata'' at times, namely ''Gasteracantha irradiata'' (by Thorell, 1859), ''Gasteracantha sanguinolenta'' (by Keyserling, 1877) and ''Gasteracantha transversa'' (as subspecies ''G. v. longicornis'' by Strand, 1907), further complicating the i ...
