Argiope (spider)
The genus ''Argiope'' includes rather large spiders that often have a strikingly coloured abdomen. These spiders are distributed throughout the world. Most countries in tropical or temperate climates host one or more species that are similar in appearance. The etymology of ''Argiope'' is from a Latin word '' argentum'' meaning silver. The carapace of ''Argiope'' species is typically covered in silvery hairs, and when crawling in the sun, they reflect it in a way that gives them a metallic, white appearance. Description As with most orb weavers, they have a third claw which is used to weave their complex webs. There is significant sexual dimorphism among the various species, with females measuring 19mm-28mm (0.75”-1.1”) and males coming in at 5mm-9mm (0.20”-0.35”). Their webs can be quite large, usually containing a signature zig-zag pattern, called a stabilimentum. They sport black and yellow patterning on their abdomen, and occasionally on their legs, although most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Argiope Bruennichi
''Argiope bruennichi'', commonly known as the wasp spider, is a species of orb-weaver spider found across Central and Northern Europe, several regions of Asia and Africa and the Azores. Like many other members of the same genus '' Argiope'', this species features distinctive yellow, white and black markings on its abdomen. Web The spider builds a spiral orb web at dawn or dusk, most often in long grass just above ground level. The zigzag-shaped web decoration, named the stabilimentum, is featured at the centre of the orb. Its function is not currently known, though studies have indicated that the webs containing stabilimentia are damaged less often by birds flying through them. When prey gets trapped in the web, the spider immobilizes it by wrapping it in silk. The prey is then bitten and injected with a paralyzing venom and a protein-dissolving enzyme.

UV Light
Ultraviolet radiation, also known as simply UV, is electromagnetic radiation of wavelengths of 10–400 nanometers, shorter than that of visible light, but longer than X-rays. UV radiation is present in sunlight and constitutes about 10% of the total electromagnetic radiation output from the Sun. It is also produced by electric arcs, Cherenkov radiation, and specialized lights, such as mercury-vapor lamps, tanning lamps, and black lights. The photons of ultraviolet have greater energy than those of visible light, from about 3.1 to 12 electron volts, around the minimum energy required to ionize atoms. Although long-wavelength ultraviolet is not considered an ionizing radiation because its photons lack sufficient energy, it can induce chemical reactions and cause many substances to glow or fluoresce. Many practical applications, including chemical and biological effects, are derived from the way that UV radiation can interact with organic molecules. These i ...

Spider Silk
Spider silk is a protein fibre or silk spun by spiders. Spiders use silk to make webs or other structures that function as adhesive traps to catch prey, to entangle and restrain prey before biting, to transmit tactile information, or as nests or cocoons to protect their offspring. They can use the silk to suspend themselves from height, to float through the air, or to glide away from predators. Most spiders vary the thickness and adhesiveness of their silk according to its use. In some cases, spiders may use silk as a food source. While methods have been developed to collect silk from a spider by force, gathering silk from many spiders is more difficult than from silk-spinning organisms such as silkworms. All spiders produce silk, although some spiders do not make webs. Silk is tied to courtship and mating. Silk produced by females provides a transmission channel for male vibratory courtship signals, while webs and draglines provide a substrate for female sex pheromone ...

Argiope Aurantia
''Argiope aurantia'' is a species of spider, commonly known as the yellow garden spider, black and yellow garden spider, golden garden spider, writing spider, zigzag spider, zipper spider, black and yellow argiope, corn spider, Steeler spider, or McKinley spider. The species was first described by Hippolyte Lucas in 1833. It is common to the contiguous United States, Hawaii, southern Canada, Mexico, and Central America. It has distinctive yellow and black markings on the abdomen and a mostly white cephalothorax. Its scientific Latin name translates to "gilded silver-face" (the genus name '' Argiope'' meaning "silver-face", while the specific epithet ''aurantia'' means "gilded"). The body length of males range from ; females range from . The average female body mass is about 752.0 mg. These spiders may bite if disturbed or harassed, but the venom is harmless to non-allergic humans, roughly equivalent to a bumblebee sting in intensity.

Web Decorations
A stabilimentum (plural: stabilimenta), also known as a web decoration, is a conspicuous silk structure included in the webs of some species of orb-web spider. Its function is a subject of debate. Origin Likely, the use of stabilimenta evolved independently at least nine different times. ''Araneus'' and ''Gasteracantha'' make silk stabilimenta, while ''Cyclosa'' and the closely related ''Allocyclosa bifurca'' make stabilimenta of silk, detritus, and their egg sacs. All those evolved independently from those of '' Argiope'', although some decorations of ''Allocyclosa bifurca'' closely resemble those of ''Argiope''.Eberhard 2006 Form Although web decorations are common in several spider species in the families Araneidae, Tetragnathidae, and Uloboridae, they are probably best known from spiders of the genus '' Argiope''. This genus includes several species known as the ''Saint Andrew's Cross spiders'', so named for their habit of resting in their webs with their legs outstretched ...

Saltire
A saltire, also called Saint Andrew's Cross or the crux decussata, is a Heraldry, heraldic symbol in the form of a diagonal cross. The word comes from the Middle French , Medieval Latin ("stirrup"). From its use as field sign, the saltire came to be used in a number of flags, in the 16th century for Flag of Scotland, Scotland and Cross of Burgundy, Burgundy, in the 18th century also as the ensign of the Ensign of the Russian Navy, Russian Navy, and Saint Patrick's Saltire, for Ireland. Notable 19th-century usage includes some of the flags of the Confederate States of America. It is also used in the flag of Jamaica and on Seal (emblem), seals, and as a Charge (heraldry), heraldic charge in Coat of arms, coats of arms. The term saltirewise or in saltire refers to heraldic charges arranged as a diagonal cross. The Escutcheon (heraldry), shield may also be Division of the field, divided per saltire, i.e. diagonally.

Spider Web
A spider web, spiderweb, spider's web, or cobweb (from the archaic word ''Wikt:coppe, 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. The term "spider web" is typically used to refer to a web that is apparently still in use (i.e., clean), whereas "cobweb" refers to a seemingly abandoned (i.e., dusty) web. 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 thi ...
