Harvard University Largest-ever study of spider genetics shows orb weaver spiders do not share common origins For decades, the story of spider evolution went like this: As insects became more and more diverse, with some species taking to the skies, spiders evolved new hunting strategies, including the ability to weave orb-shaped webs to trap their prey. From that single origin, the story goes, orb-weaver spiders diverged along different evolutionary paths, leading to today, where...

Spiders In Space Weave A Web Of Scientific Knowledge
2014-04-24 03:44:31

Laura Niles, NASA While spiders were busy spinning webs in space, researchers on Earth weaved their knowledge of this activity into educational materials to inspire and motivate students. Now, this free, Web-based guide is being re-released through Scholastic and Sony Pictures as curriculum for educators to leap on the excitement surrounding the release of the film, “The Amazing Spider-Man 2.” For those who may have missed it, this guide’s inspiration came from real science using...

New Spider Species Bagged By Students On Field Course
2014-03-28 18:07:58

Pensoft Publishers As a spin-off (pun intended) of their Tropical Biodiversity course in Malaysian Borneo, a team of biology students discover a new spider species, build a makeshift taxonomy lab, write a joint publication and send it off to a major taxonomic journal. Discovering a new spider species was not what she had anticipated when she signed up for her field course in Tropical Biodiversity, says Elisa Panjang, a Malaysian master's student from Universiti Malaysia Sabah. She is...

Spider Omnivore Eats Pollen
2013-12-18 11:24:48

[ Watch the Video: Pollen On The Menu For Orb-Weaver Spiders ] Brett Smith for redOrbit.com - Your Universe Online Spiders have long been thought of as creepy-crawly predators, but a new study from a couple of European researchers has found that these arachnids will munch on pollen from time to time as well. According to their report in the journal PLOS ONE, the study team found that the diet of younger, common orb-weaver spiders includes around 25 percent pollen. The spiders were...

Amber Catches 100 Million-year-old Spider Attack
2012-10-09 04:32:07

April Flowers for redOrbit.com - Your Universe Online Researchers at Oregon State University have found an extraordinarily rare fossil. Trapped in amber is what the research team describes as the only example of a spider attack on prey caught in its web — a 100 million year old snapshot of an engagement frozen in time. Found in the Hukawng Valley of Nyanmar, the fossil dates from the Cretaceous between 97 and 100 million years ago. Giving some evidence to oldest examples of spider...

Orb Weaver Spider Builds Intricate UV-Decorated Webs To Attract Insects
2012-09-20 10:29:19

Lawrence LeBlond for redOrbit.com - Your Universe Online The ultraviolet decorations and intricate patterns of the orb-weaver spider´s web is used to attract food, say scientists from the University of Incheon, whose studies of a common orb-weaver spider species are published in the journal Behavioral Ecology and Sociobiology. Researchers suggest that the UV light-reflecting patterns seen in the webs of orb-weavers, particularly the Wasp Spider, could trick flying insects into...

Scientists Search For Spider Web's  Strength
2012-02-02 09:38:05

Scientists report that they have solved the riddle of how spider webs can withstand different levels of stress - including hurricane force winds - without collapsing. Researchers, led by Markus Buehler of the Massachusetts Institute of Technology (MIT), used computer simulations to find out how silk structures respond to different levels of stress. What they found was quite remarkable. Reporting in the journal Nature, the researchers found that web durability does not only rely on silk...

Researchers have shown for the first time how Golden orb web spiders (Nephila antipodiana) add a chemical to their web silk to repel invading ants. The finding adds a chemical defense to the impressive properties of spider silk, already known to be very strong, elastic and adhesive, and may provide new opportunities for pesticide design. The study was led by researchers from the National University of Singapore (NUS) and the University of Melbourne, and is published in the journal...

A spectacular golden textile, conceived and created by Simon Peers and Nicholas Godley in Madagascar from silk thread collected from over one million Golden Orb spiders (Nephila madagascariensis), will go on exhibit at the Art Institute of Chicago, the country's second largest art museum. On special loan to the museum from Mssrs. Peers and Godley as part of the inaugural celebration of the museum's new galleries devoted to African art and Indian art of the Americas, the Spider Silk textile...

Decorative white silk crosses are an ingenious tactic used by orb-weaving spiders to protect their webs from damage, a new study from the University of Melbourne has revealed. The team, led by Dr Andre Walter and Professor Mark Elgar from the University of Melbourne's Department of Zoology, found that orb-weaving spiders respond to severe damage to their webs by building bigger silk crosses, but if the damage is mild they don't bother adding extra decoration. Professor Mark Elgar said web...

The Golden Silk Spider (Nephila clavipes) is a species of orbweaver spider. It is found in the warmer regions of the Americas. In the United States, this species ranges throughout the coastal southeast and inland, from North Carolina to Texas. In many areas its distribution is somewhat localized and may be absent in many areas over wide areas. In some arboreal or swampy areas, adults and their webs can be found in large concentrations, especially near the coast. This species is also...

The Joro Spider (Nephila clavata) is a species of arachnid that is a member of the golden orb-web spider group. It is found in Japan (except Hokkaidō), Korea, Taiwan and China. The web of the female can reach up to 39 inches in width. The yellow threads appear rich gold in sunlight. The web has three layers: the central orb, plus two irregular layers in front of and behind the orb. The adult female is about 1 inch. The male is much smaller and is no bigger than 0.4 inches. The female...

The Autumn Spider (Metellina segmentata) is a species of spider that has a Palearctic distribution and has been introduced to Canada. Adults are normally found from August to October. The preferred habitat is open wood edges or gardens. This is one of the most common orb-weaving spiders. The web of this spider has no threads at its center. Most webs are built low above the ground. The spider sits at the center during the day for long periods of time. Sometimes it will hide at the edge and...
