Description

Female is about 8–12 mm long and male is 3.5-4.5 mm. After Cephalothorax greyish brown with hairs. Sternum heart shaped with hairy pubescent white patch. Palps bear spines. Legs greyish brown and hairy. Femora dorsally yellowish. Abdomen pentagonal and hairy. Dorsum yellowish with brown transverse bands. Three sigilla pairs distinct. Ventrum dark brownish with two longitudinal white patches.[ citation needed ]

Ecology

Like other species of the same genus, it is known as a "signature spider"; it builds a web with a zig-zag stabilimentum somewhat resembling letters. The mature female of A. anasuja always rests at the centre of the orb with her head facing downwards. The orb has an opening at the centre and when disturbed she goes through the hole and exits on the other side of the plane of the web. [2]

They are commonly found on flora of Mimosaceae family. They prefer to make the web in a plane of shadow in the daylight.[ citation needed ]

Reproduction

Male is smaller than female. Male spins a web around the female's web, which is known as a companion web. After the mating, as in other common spiders, female kill the male. Female lay eggs on the companion web and wrap them up into a sac. Spiderlings eat each other in the sac until the strongest spiderling break the sac wall. [3] The sac can hold from 400 to 1,400 eggs.

<i>Argiope</i> (spider) Genus of spiders

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.

<i>Heteropoda venatoria</i> Species of spider

Heteropoda venatoria is a species of spider in the family Sparassidae, the huntsman spiders. It is native to the tropical regions of the world, and it is present in some subtropical areas as an introduced species. Its common names include giant crab spider, pantropical huntsman spider or cane spider.

<i>Nephila</i> Genus of spiders

Nephila is a genus of araneomorph spiders noted for the impressive webs they weave. Nephila consists of numerous species found in warmer regions around the world, although some species formerly included in the genus have been moved to Trichonephila. They are commonly called golden silk orb-weavers, golden orb-weavers, giant wood spiders, or banana spiders.

<i>Argiope keyserlingi</i> St Andrews cross spider

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 spiders, A. keyserlingi shows considerable sexual dimorphism, with the females being 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.

The black house spider or common black spider is a common species of cribellate Australian spider, introduced to New Zealand and Japan. A closely related species, Badumna longinqua, the grey house spider, has a similar distribution, but has also been introduced to the Americas.

<i>Argiope bruennichi</i> Species of orb-weaver spider

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, plus parts of the Middle east, North 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.

<i>Argiope aurantia</i> Species of spider

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 body length of males range from 5–9 mm (0.20–0.35 in); females range from 19–28 mm (0.75–1.10 in). 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.

<i>Araniella cucurbitina</i> Species of spider

Araniella cucurbitina, sometimes called the "cucumber green spider", is a spider of the family Araneidae. Araniella cucurbitina is found across Europe, Western Asia, Central Asia and Japan. The cucurbitina in the name comes from the word cucurbit which is a family of plants including cucumbers.

They are solitary spiders, residing in daily spun orb webs. Z. x-notata is a member of the genus Zygiella, the orb-weaving spiders. The adult female is easily recognized by the characteristic leaf-like mark on her posterior opisthosoma, caudal to the yellow-brown cephalothorax.

<i>Mastophora hutchinsoni</i> Species of spider

The genus is distributed extensively throughout various subtropical geographical areas including Australia, South Africa, Oriental Asia, and the Americas and is not found in Europe. The hunting behavior of adult female M. hutchinsoni is unusual because they are bolas spiders. They mimic moth pheromones to attract male moths, and female M. hutchinsoni have evolved to alter their chemical release to target different moths. They then capture their prey with a sticky drop on the end of a silk line, resembling a bolas.
