redOrbit Staff & Wire Reports - Your Universe Online Living in the city can have its benefits – especially if you’re an arachnid, according to new research reporting that some types of spiders grow larger and have increased reproductive capabilities in urban areas. Writing in the latest edition of the journal PLOS ONE, scientists from the University of Sydney School of Biological Sciences explain that golden orb-weaving spiders tended to have smaller bodies when they lived in...

Cyclosa Spider Hunts With Decoys
2012-12-20 20:08:07

Lee Rannals for redOrbit.com — Your Universe Online While salt licks may be one intelligent ploy by man to attract deer for hunting, its got nothing on the method used by one Amazonian arachnid. One tiny spider in the Peruvian Amazon builds an elaborate decoy spider, and hangs it from its web in order to trick predators into getting stuck in its web. The artful dodger takes it time crafting up decoys from dead insects, debris and leaves as what scientists suspect is a defense...

Discerning Males Remain Faithful

Discerning males remain faithful...if you are a spider. Sex for male orb web spiders (Argiope bruennichi) is a two shot affair since the act of mating destroys their genitalia. If they survive being eaten during their first encounter with a female, they have two choices — to mate again with the same female (monogynous) or try to find a new partner (bigynous). New research published in BioMed Central's open access journal Frontiers in Zoology shows that choice of mating behavior for A....

According to new research published in the journal Naturwissenschaften, spiders do not stick to their own webs because of the way they move. The spiders ability to not stick to its own web was originally attributed to a special coating on their legs. However, researchers at the Smithsonian Tropical Research Institute and University of Costa Rica used modern imaging technology to record close-up footage that better explains the ability. The team combined a video camera and a...

(Ivanhoe Newswire) -- Young house spiders weave webs with perfect angles and regular patterns, but as they reach old age their webs deteriorate, showing gaping holes and erratic weaving. By using spiders as a simple model this research may provide insight into how age affects behavior in other organisms, including humans. The reason web building skills are lost as spiders grow older may be due to degeneration of the central nervous system. PhD researcher, Mylne Anotaux, from Nancy University...

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...

Studying spider silk, NSF-supported researchers learn about the properties of this sticky material, and their findings could lead to new bio-adhesives and glues that work under water Ali Dhinojwala and Vasav Sahni consider themselves materials scientists, not biologists. They study surfaces, friction and adhesion. Nevertheless, they have discovered that understanding how nature makes things stick sometimes means getting up close and personal with the creatures responsible. When they...

By Maggie Fox, Health and Science Correspondent WASHINGTON (Reuters) - A tiny piece of spider web, frozen in a drip of tree sap 110 million years ago, shows spiders that wove perfect orb webs evolved much earlier than had been believed, scientists reported on Thursday. A second study looking at spider genetics suggests that web-weaving arachnids evolved as long as 136 million years ago, in the Cretaceous period, when dinosaurs roamed and mammals were small, scurrying things. Both studies,...

The Leaf Curling Spider (Phonognatha graeffei) is a species of spider that is found in Australia. It is commonly found in urban areas in the northeastern, eastern and southern states. The spider is commonly found in open woodland and forest habitats as well as urban and suburban gardens. The adult female is about 0.45 inches while the male is about half the size of the female (about .025 inches). Both male and female are similar in appearance. The legs and body are reddish-brown and there...
