Scientists have found that spiders are able to determine the wind direction limbs. If the wind is warm and mild — they spin webs and move through it.

Their webs arthropods use different: weave her cocoon and catch victims, producing a protective film for the eggs. And besides, the spiders made the so-called "sails" with which traveling by air. Biologists knew about this phenomenon in the seventeenth century, but, until recently, it was not subjected to thorough study.

In the newest study, the researchers observed the behavior of species of the genus Xysticus, placing it on the specially designed shape of the fungus. The experiment was conducted in the Park Lilienthal in Berlin, named in honor of test pilot Otto Lilienthal. Biologists also conducted tests in a wind tunnel, where he was able to regulate the strength of the wind and air temperature.

So they found out that the spiders are aeronauts move only in warm weather. First, they lift for a few seconds the legs, fixing the wind direction. If blowing a pleasant breeze, the animals produce a wide web, building the sail is triangular in shape, which lifts them up. Thus, biologists were able to establish that before you go on a trip spiders are guided by weather conditions.
