Araneus praesignis | |
Araneus praesignis [1] is a species of orb-weaving spider found in Queensland, Australia, where it is widespread and common in well-vegetated areas. The Atlas of Living Australia [2] shows a record from New South Wales. It has bold black blobs on its rear, perhaps mimicking eyes. In 2014, Carly Brooke Martinetti gave it the common name "Alien Butt Spider," [3] by which it became internationally known. [4] [5] [6] [7]
Both males (body length 5 mm) and females (body length 7 mm) of Araneus praesignis have large black decorations on the dorsal posterior of the abdomen, which are thought to be a case of Batesian mimicry. [4] The spider was described by Ludwig Koch in Die Arachniden Australiens, 1872.
Araneus praesignis shelters during the day in a silk-bound retreat made in a non-fully-closed leaf nearby, where its web is erected at night. Its food is night-flying insects and other invertebrates. [4] It is harmless to humans and can be handled by people without medical consequences, although allergic reactions may be possible. [8]
The spider species Araneus diadematus is commonly called the European garden spider, cross orbweaver, diadem spider, orangie, cross spider, and crowned orb weaver. It is sometimes called the pumpkin spider, although this name is also used for a different species, Araneus marmoreus. It is an orb-weaver spider found in Europe, where it is native, and North America, where it was introduced.
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 and is endemic to Australia. They are relatively small spiders, reaching a maximum total body length of only around 12 mm (0.47 in) for females, and 5 mm (0.20 in) 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.
Araneus quadratus, the four-spot orb-weaver, is a common orb-weaver spider found in Europe and Central Asia, and as far as the Kamchatka Peninsula and Japan. Females can reach 17 mm in length, especially when gravid, with males around half that. They are quite variable in appearance, ranging from brown to bright orange or green, but they always have the characteristic four white spots on the abdomen. The darker color morphs are easier to identify, due to the contrast between the white spots and the rest of the body. The legs are sometimes brightly striped.
The black house spider or common black spider is a common species of cribellate Australian spider, introduced to New Zealand,Japan and South Africa. A closely related species, Badumna longinqua, the grey house spider, has a similar distribution, but has also been introduced to the Americas.
Phidippus audax, the Bold jumper or Daring jumping spider, is a common species of spider belonging to the genus Phidippus, a group of jumping spiders easily identified by their large eyes and their iridescent chelicerae. Like all jumping spiders, they have excellent stereoscopic vision that aids them in stalking prey and facilitates visual communication with potential mates during courting. Bold jumping spiders are native to North America and have been introduced to Hawaii, Nicobar Islands, Azores, and the Netherlands. They are typically black with a distinct white triangle on their abdomen.
The barn spider is a common orb-weaver spider native to North America. They are around three-quarters of an inch (20 mm) in length and are usually yellow and brown in color. They often construct their webs in wooden human structures, hence their common name. The species is notable for being the basis for the character Charlotte in the book Charlotte's Web by American writer E. B. White.
Nephilengys is a genus of tropical spiders of the family Nephilidae, consisting of two currently described species. The genus Nephilingis has been split off from this genus. Both genera have been called hermit spiders from the habit staying in their retreats during the day; the name eunuch spiders has been used for Nephilengys alone. Males may sever parts of their palpal bulbs after copulation.
Araneus marmoreus, commonly called the marbled orbweaver, is a species of spider belonging to the family Araneidae. It is sometimes also called the pumpkin spider from the resemblance of the female's inflated abdomen to an orange pumpkin. It has a Holarctic distribution.
Phonognatha graeffei, referred to as the leaf curling spider, is a common Australian spider found in woodlands and urban areas in the northeastern, eastern and southern states. A member of the family Araneidae, the orb-weavers, it was previously placed in Tetragnathidae.
Plebs bradleyi, synonym Araneus bradleyi, is a spider in the orb-weaver family Araneidae. Known as the enamelled spider, it is a common Australian spider. It occurs in Tasmania, New South Wales, Queensland and Victoria.
Tetragnatha extensa is a species of spider found across the Northern Hemisphere. It has an elongate body, up to 11 mm (0.43 in) long, and adopts a straight line posture when alarmed. It lives on low vegetation in damp areas, and feeds on flying insects which it catches in its web.
Araneus mitificus, commonly known as the kidney garden spider or pale orb weaver is a species of orb-weaver spider found in South, East, and Southeast Asia.
The spider species Plebs eburnus is commonly referred to as the eastern grass orb-weaver or the eastern bush orb-weaver, and sometimes more simply as the bush orb-weaver. It is an orb-weaver spider from the family Araneidae endemic to Australia. It is a very common spider with distinctive white markings, which give it the species name eburnus pertaining to ivory. It is found in scrub and tall grasses where the female constructs a vertical web usually no more than 2 metres from the ground, and stays there day and night. The web of some of these spiders has been seen to be decorated with nearly vertical stabilimentum. The stabilimentum of the related P.cyphoxis is usually observed vertical.
Neoscona theisi is a species of spider in the family Araneidae. Spiders in the genus Neoscona have a mostly pantropical distribution.
Cyrtophora hirta is a species of tent spider found in the Australia. The southern range of distribution is near Sydney, though there are New Guinea and Tasmanian records on the Atlas of Living Australia. Ludwig Koch described the species in 1872 from specimens from Bowen, Queensland.
Australomisidia cruentata, one of the crab spiders, is a small spider found in Australia. The body length of the female is up to 5 mm, the male 3 mm. An ambush predator, often seen on flowers in the Pultenaea group of egg and bacon plants, belonging to the pea family. The egg sac is also laid on the flowers. Petals being fastened with silk in a chamber. The spider stays with the eggs, probably still hunting from the entrance of the retreat, with the egg sac nearby. Prey is small flying insects. The genus Australomisidia was created in 2014, the word being a combination of Australia and Thomisidae, the crab spiders.
Tasmanicosa godeffroyi, a wolf spider, is a mid sized spider found in some states of Australia. It is perhaps the most commonly noticed of the wolf spiders in Australia. It is variable in pattern and colour, though the underside of the abdomen is black. Wolf spiders tend to rest at the entrance of their burrows, and their eyes reflect the light of passing cars or torchlight. The burrow has a thin veil of silk, without a lid, unlike some other wolf spiders. The burrow is circular in cross section and travels down for around 15 cm, then parallel with the ground for the next 15 cm. The body length of the female is up to 27 mm, the male 25 mm.
Cymbacha saucia is a crab spider found in Australia. The body length of the female is up to 7 mm, the male 4 mm. A cryptic small species, the colour is usually brown, grey and black. Often found in a folded leaf, used as a retreat.
Araneus talipedatus the slender green orb-weaver spider is a species of orb weaver in the family Araneidae. Found in many parts of Australia, this species is active in daytime and builds a conventional orb web. The female has a body length of up to 9 mm, males to 7 mm. Long hairs grow on the legs and pedipalps.
