Spiders are already known to fly by using their silk to catch the wind. The spiders were able to point their legs up to catch the wind, acting as a sail. The scientists gathered 325 adult spiders from several nature reserves around Nottinghamshire and placed them on water trays to observe how they would react to air generated through a pump. As awesome as it would be to have a fleet of blimp-bound spiders chasing down prey, the behavior has little to do with hunting – at least not directly. “We have to change our idea of risk concerning ballooning“, he says.

These skills could help spiders who are not capable of ballooning or could be useful in case of heavy rain or floods. And like it or not, that’s exactly what spiders have done. Ballooning spiders are estimated to move up to 30 km per day when wind conditions are suitable, helping in their quest for new habitats and resources.
Researchers from the originial and University of Nottingham have investigated 352 robots, sense 21 growers allotted, which often they actually harvested from quality supplies in Nottingham.
On Friday, the journal BMC Evolutionary Biology published a research report that shows how spiders have this unique ability to move across significant distances and how they colonize new areas pretty quickly. These spiders were then taken back to the universities “Spider Lab” for testing.
All of the spiders were able to stand on water thanks to their highly water-repellent legs. Most notably, numerous spiders demonstrated what the researchers term “sailing” behavior. They even used the web silk as an anchor to stop them or help them slow down their movement on water.

Spiders are able to travel across water using their legs as sails and silk as an anchor, scientists have found. The arachnids came from the linyphiid and tetragnathid families, which together represent around 13 percent of all known species. Though the adapting ability of spiders differed from species to species, researchers found that the one that used ballooning method, were the best suited for water landing. Images taken from the paper. It allowed these creatures to sail virtually in turbulent, still, fresh and salt water conditions. When confronted with wind on a dry surface, nearly all of the spiders hunkered down to duck out of the gust. “Death mimicry behavior is likely to be a predator avoidance strategy, as is common to many animals”. But with these behavioral adaptations, it could allow spiders to survive encounters with aquatic environments. Such spiders will also have greater protection from flash floods.
