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.
A stabilimentum, 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.
Argiope keyserlingi is a species of orb-web spider found on the east coast of Australia, from Victoria to northern Queensland. It is very similar in appearance to a closely related north Queensland species, Argiope aetherea. A. keyserlingi is commonly found in large populations in suburban parks and gardens, particularly among the leaves of Lomandra longifolia. Like many species of orb-web spider, A. keyserlingi shows considerable sexual dimorphism, as the females are many times larger than the males. Mature females can be seen during the summer, and seeing multiple males on the web of one female is not uncommon.
Argiope picta is a species of orb web spider found in tropical areas of Queensland, Australia and Papua New Guinea up to the Moluccas. This species is similar in size to the sympatric Argiope aetherea; females can be distinguished from those of A. aetherea via extensive differences in abdominal colouration and patterns. The males of these two species are almost indistinguishable.
Argiope mascordi is a species of orb-web spider found in Queensland, Australia. The females of this species are smaller and less colourful than many other spiders in the genus Argiope. Males are larger than many other Argiope. Web decorations in this species are interesting in that A. mascordi juveniles construct a cross and adults construct a disc. The reason for this apparent reversal in decorating behaviour remains unknown.
Argiope bruennichi is a species of orb-web spiders distributed throughout Central and Northern Europe, North Africa, parts of Asia, and the Azores archipelago. Like many other members of the genus Argiope, it has strikingly yellow and black markings on its abdomen.
Argiope appensa, also referred to as the Hawaiian garden spider or banana spider, is an orb-weaving spider belonging to the family Araneidae.
Argiope argentata, commonly known as the silver argiope or silver garden spider due to the silvery color of its cephalothorax, is a member of the orb-weaver spider family Araneidae. This species resides in arid and warm environments in North America, Central America, the Caribbean and widely across South America. In the United States, it is found at least in Southern California, Florida, Arizona, and Texas. A. argentata create stabilimenta and a unique zig-zag in its web design, and it utilizes its UV-reflecting silk to attract pollinating species to prey upon. Like other species of Argiope, its venom is not harmful to humans; however, it can be employed to immobilize its prey. A. argentata engages in sexual cannibalism either mid- or post-copulation. One aspect of particular interest regarding this species is its extinction patterns, which notably have minimal correlation with its population size but rather occur sporadically for the species.
Argiope trifasciata is a species of spider native to North and South America, but now found around the world. It can be found in certain areas of Europe, namely the Iberian Peninsula, the Canary Islands, and Madeira. The similar looking Argiope bruennichi is common in the Azores. They typically begin to appear during autumn from early September to late October as temperatures start dropping.
Argiope protensa, commonly known as the tailed grass spider or teardrop spider, is a species of spider in the orb weaver family, Araneidae. This species is fairly common and widespread in Australasia, but like many spider species, little is known of its ecology, biology, or life history.
Argiope anasuja, is a species of harmless orb-weaver spider found from the Seychelles to India, Pakistan and Sri Lanka, in the Maldives and in the Brazil.
Argiope catenulata, also known as the grass cross spider, is a species of orb-weaver spiders ranging from India to the Philippines and Papua New Guinea, and also found in Australia in 2019. Like other species of the same genus, it builds a web with a zig-zag stabilimentum.
Argiope pulchella is a species of the orb-weaver spider family, Araneidae. It ranges from India to China and can be found on Java. It is a synanthropic species, often living in habitats associated with humans.
Argiope aemula, commonly known as the oval St Andrew's cross spider, is a species of spider in the family Araneidae which is native to southeast Asia, found from India and Sri Lanka to the Philippines, Indonesia, and Vanuatu. It is one of the giant, conspicuous "signature spider" species of the genus Argiope, observed in tropical and subtropical grasslands.
Argiope magnifica is a species of orb web spider found in tropical areas of north-east Queensland, Australia, eastern Papua New Guinea and the Solomon Islands. It is commonly known as the magnificent St Andrew's cross spider. This species is similar in size to the sympatric Argiope keyserlingi; females can be distinguished from those of A. keyserlingi via extensive differences in abdominal colouration and patterns. The males of these two species are almost indistinguishable.
Argiope radon is a species of orb web spider native to Australia. It is found in tropical areas of the Northern Territory, Western Australia and Queensland. It is commonly known as the Northern St Andrew's cross spider.
Argiope versicolor, the multi-coloured Saint Andrew's cross spider, is a species of orb-weaver spider found mostly in Southeast Asia, from China to Indonesia.
Argiope australis, the common garden orb web spider, is an orb-web spider.
Argiope dietrichae is a rare species of orb-web spider found in the northern parts of Western Australia and the Northern Territory. It was first described by Levi in 1983, and it was named for Amalie Dietrich who collected specimens for the Godeffroy Museum in Hamburg.
Gea eff is a species of orb-weaver spider. It is found in Papua New Guinea. The arachnologist Herbert Walter Levi formally described the species in 1983. While it was still undescribed, Michael H. Robinson and colleagues reported on its courtship and mating behaviors. Gea eff has the shortest scientific name of any spider species.
