Spiders Can Protect Plants From Insects
Spiders can protect plants from leaf-eating insects in exchange for dollops of sugary nectar. Researchers in New Jersey found that the presence of jumping spiders helped plants boost their seed production and scared off insects. (1999-05-12)

Spiders partial to a side order of pollen with their flies
Spiders may not be the pure predators we generally believe, after a study found that some make up a quarter of their diet by eating pollen. Dr Dirk Sanders of the University of Exeter demonstrated that orb web spiders -- like the common garden variety -- choose to eat pollen even when insects are available. (2013-12-18)

Scientists crack the spiders' web code
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, Australia, has revealed. (2011-05-31)

When enemies come to help
The enemy of my enemy is my friend. Now researchers at the University of Zurich show that this principle also holds for crab spiders and flowering plants. While it's true that the spiders do eat or drive away useful pollinators such as bees, they're also attracted by floral scent signals to come and help if the plant is attacked by insects intent on eating it. (2018-04-10)

What are 3-D spider webs for?
In an article published in the January 2003 issue of Ecology Letters, researchers led by a team at Cornell University report that three-dimensional spider webs are associated with a dramatic decrease in predation by mud-dauber wasps, major worldwide predators of spiders. (2003-01-02)

Pest control breakthrough - from a spider's stomach
DNA found in a spider's stomach could herald a breakthrough in the fight against farm pests, which cause millions of dollars of damage to crops. Cardiff University, UK, scientists, led by Dr Bill Symondson in the School of Biosciences, have become the first to use DNA-based techniques to analyse the content of spiders' guts to identify the prey they have eaten in the field. (2003-12-12)

Whip spiders only look terrifying, UCLA biologist reports
UCLA biologist Kenneth Chapin spent several weeks in dark caves in Puerto Rico inhabited by an estimated 300,000 bats -- many of which whizzed right by him -- as well as snakes, cockroaches and spiders. He was studying poorly understood whip spiders, which are related to spiders and scorpions. On March 14, 2016 he published his findings about their behavior. (2016-03-15)

Buzz kill: Ogre-faced spiders 'hear' airborne prey with their legs
In the dark of night, ogre-faced spiders with dominating big eyes dangle from a silk frame to cast a web and capture their ground prey. But these spiders also can capture insects flying behind them with precision, and Cornell University scientists have now confirmed how. (2020-10-29)

2 miniature spider species discovered in giant panda sanctuaries of China
Two tiny, bizarre shaped spider species have been discovered in the Sichuan province and Chongqing city of China. The two species belong to the understudied Mysmenidae family, which prove difficult to find due to their small size (under 2 mm in total) and their cryptic lifestyle habits. The study was published in the open-access journal Zookeys. (2013-05-22)

More than bugs: Spiders also like to eat vegetarian
Spiders are known to be the classic example of insectivorous predators. Zoologists from the University of Basel, the US and UK have now been able to show that their diet is more diverse than expected. Their findings show that spiders like to spice up their menu with the occasional vegetarian meal. The Journal of Arachnology has published the results. (2016-03-14)

World's most venomous spiders are actually cousins
Two lineages of dangerous arachnids found in Australia--long classified as distantly related in the official taxonomy--are, in fact, relatively close evolutionary cousins. The lineages include the most venomous spiders in the world. The findings could help in the development of novel antivenoms, as well as point to new forms of insecticides. (2018-02-15)

An end to arachnophobia 'just a heartbeat away'
Researchers have discovered that exposing people with phobias to their fear -- for examples, spiders for those who have arachnophobia -- at the exact time their heart beats, led to the phobia reducing in severity. (2018-10-30)

What's hiding behind the trapdoor?
A Griffith University researcher has discovered several new species of trapdoor spider -- and you'd never guess where. (2016-08-30)

Virtual opponents reveal fighting strategies of male jumping spiders
Jumping spiders are known for their excellent vision. This attribute may enable them to visually size up a potential opponent and decide whether to step away from a possible fight even before it starts. However, in live fights, jumping spiders may have limited opportunity to show this skill. This is according to Rowan McGinley and Phillip Taylor of Macquarie University in Sydney, Australia. Their findings are published in Springer's journal Behavioral Ecology and Sociobiology. (2016-04-21)

Caught in a trap: bumblebees vs. robotic crab spiders
Bumblebees learn to avoid camouflaged predators by sacrificing foraging speed for predator detection, according to scientists from Queen Mary, University of London. (2008-09-04)

Lurking in the darkness of caves In Southeast China, scientists discover and describe five new species of these exciting group of spiders. The study was published in the open access journal ZooKeys. (2014-03-14)

Temperature helps drive the emergence of different personalities in spiders
Not a single aggressive spider was able to reproduce at 93 degrees Fahrenheit and most of them died at that temperature. But when Ingley and his team added docile spiders to the mix, the aggressive spiders thrived in that diverse community at that temperature. (2016-07-21)

Fish-eating spiders discovered around the world
Spiders from five different families prey on small fish in the wild. (2014-06-18)

Spider baby boom in a warmer Arctic
Climate change leads to longer growing seasons in the Arctic. A new study, which has just been published in Proceedings of the Royal Society B, shows that predators like wolf spiders respond to the changing conditions and have been able to produce two clutches of offspring during the short Arctic summer. The greater number of spiders may influence the food chains in Greenland. (2020-06-25)

Moving in for the winter toxic brown recluse spiders pose danger
As the cold weather creeps in, so do brown recluse spiders. True to their name, the brown recluse is a shy, reclusive spider looking for a warm home. Drawn to clutter, closets and complex storage environments, the spiders actually want to stay away from humans. But, if care is not taken, people could find themselves sharing their home with one of (2008-12-15)

Spiders eat 400-800 million tons of prey every year
It has long been suspected that spiders are one of the most important groups of predators of insects. Zoologists at the University of Basel and Lund University in Sweden have now shown just how true this is -- spiders kill astronomical numbers of insects on a global scale. The scientific journal The Science of Nature has published the results. (2017-03-14)

Web weaving skills provide clues to aging
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. This work will be presented at the Society for Experimental Biology Annual Conference in Glasgow on July 2, 2011. (2011-07-01)

New study provides key to identifying spiders in international cargo
Spiders found in international cargo brought into North America are sometimes misidentified, which can lead to costly and unwarranted eradication measures. A new study provides a key to identifying spiders commonly found in international cargo. (2014-10-01)

Giant Antarctic sea spiders weather warming by getting holey
Scientists have wondered for decades why marine animals that live in the polar oceans and the deep sea can reach giant sizes there, but nowhere else. University of Hawai'i at Manoa zoology Ph.D. student Caitlin Shishido, with UH researcher Amy Moran and colleagues at the University of Montana, went to Antarctica to test the prevailing theory -- the 'oxygen-temperature hypothesis' -- that animals living in extreme cold can grow to giant sizes because their metabolisms are very slow. (2019-04-10)

New research shows how male spiders use eavesdropping to one-up their rivals
Just published this month, new research shows how spiders eavesdrop on other males and copy their courtship signals as a likely means of stealing their mate. (2012-01-04)

Just right: A spider's tale
A new study from the University of Missouri shows that southern house spiders are making size-related choices about holes and cavities in which to build their nests. (2015-03-25)

Jumping spiders are masters of miniature color vision
Jumping spiders were already known to see in remarkably high resolution, especially considering that their bodies are less than a centimeter long. Now, researchers reporting in the Cell Press journal Current Biology on May 18 have figured out how spiders in the colorful genus Habronattus see in three color 'channels,' as most humans do. (2015-05-18)

Jumping spiders can hear sound without eardrums
There really is a 'spider sense.' With help from Binghamton University's Ron Miles, researchers found that despite not having ears -- or ear drums -- jumping spiders can perceive airborne sound. (2016-10-31)

Scientists discover heterospecific mating in spiders
Researchers from Slovenia and South Africa have discovered heterospecific mating in Nephila spiders, and have published their findings on Nov. 15, 2016 in the journal Scientific Reports. Heterospecific mating means sexual encounters between males and females of different species. Such sexual interactions in arachnids are rare, and generally not expected in cannibalistic animals such as spiders. They could play an important role in determining the community structure of Nephila, possibly through reproductive interference. (2016-11-16)

Amber reveals ecology of 30 million year old spiders
Scientists at The University of Manchester and the Manchester Metropolitan University have carried out the first comparative scientific study of ancient spiders trapped in amber more than 30 millions years ago. (2006-03-01)

A whole new meaning for thinking on your feet
Smithsonian researchers report that the brains of tiny spiders may fill their body cavities and overflow into their legs. As part of research to understand how miniaturization affects brain size and behavior, researchers measured the central nervous systems of nine species of spiders, from rainforest giants to spiders smaller than the head of a pin. As the spiders get smaller, their brains get proportionally bigger, filling up more and more of their body cavities. (2011-12-12)

Fish-eating spiders discovered in all parts of the world
Spiders are traditionally viewed as predators of insects. Zoologists from Switzerland and Australia have now published a study that shows: spiders all over the world also prey on fish. The academic journal PLOS ONE has just published the results. (2014-06-18)

Spiders who eat together, stay together: UBC research
The ability to work together and capture larger prey has allowed social spiders to stretch the laws of nature and reach enormous colony sizes, UBC zoologists have found. (2008-08-05)

Spiders target sexy signals from 'vibrating' insects
Insects using vibration to attract a mate are at risk of being eaten alive by killer spiders, Cardiff University scientists have discovered. (2011-03-29)

Survival instinct, not family bonds, weave massive spider colonies together
Spiders will live in groups if environmental conditions make it too difficult for single mothers to go it alone, new research shows. (2017-03-07)

2 new enigmatic spider species with peculiar living habits from Uruguay
Scientists describe two new spider species from the Nemesiidae family. The representatives of this family live in silk lined burrows covered by a flap-like door that they build for their protection and as an ambush cover when hunting. The description of the morphology of the two new species and their living habits was described in the open access journal Zookeys. (2013-10-03)

First 'mainly vegetarian' spider described
The 40,000 or so spiders that have been described are generally known as strict predators, trapping their prey in elaborate webs or hunting them down directly. But researchers have found one notable exception to this rule: The neotropical jumping spider known as Bagheera kiplingi represents the first instance known to science of a spider that dines primarily on vegetarian fare, according to a report published online on Oct. 12 in Current Biology, a Cell Press publication. (2009-10-12)

Walking like ants gives spiders a chance
To avoid being eaten, some jumping spiders pretend to be ants. (2017-07-14)
