'Spider rain' phenomenon explained

Thousands of small spiders rained down on the Southern Tablelands, Australia. The houses of citizens not only met the creatures that can make the skin crawl, but also covered the net of the arachnid animal.

The incident is an example of a phenomenon called 'spider rain' or 'angel hair' - which refers to a silk-like threads were left behind. Ian Watson, a resident described the strange weather that houses the location of his home when the incident occurred in the Facebook page. Starting cloudy.

"Has anyone experienced 'angel hair' or millions of spiders falling from the sky today? My house is about 10 minutes from the city, and from here we can see hundreds of little spiders last fall floating in the net. My house is covered by the nest. Someone, please contact scientists!, "writes Watson in the Facebook's Goulburn Community Forum page.

Rick Vetter, retired spider expert from the University of California, Riverside, said Watson and his neighbors may witness a form of transport spiders called 'ballooning'.

"Balloning not unusual behavior among spiders," he said as quoted by LiveScience on Tuesday, May 19, 2015. "They climb to high altitudes and exposes the buttocks into the air, releasing the net. Then take off," he said , "It happens all around us all the time. We just do not realize it."

Spiders do like to fly. Before removing the net and drifted thousands of kilometers, the animal check weather conditions as well as human pilots before flying a plane. However, why the spider fly simultaneously to cause a rain-like phenomenon? Todd Blackledge, professor of biology at the University of Akron, Ohio said, that is an unusual view of the millions of spiders to fly at the same time.

He added, the spider rain may occur when a group of spiders ready to balloning, but hampered weather factors, for example. "So when the weather turns to the right conditions do balloning, they do it simultaneously," says Blackledge told LiveScience.

Goulburn residents and surrounding area were panic when the small spider falling from the sky. However, both Blackledge and Vetter said, the animals were harmless to humans.

"There are a number of small-sized species, venomous, and can be harmful to humans. However, the spider that immature still too small to have a bite force," says Blackledge.

However, large numbers of spiders could damage the plants, cover the leaves with a net so do not get enough light, "says Vetter.

Watson said the small spider can be caught in the hair on the human face. "There's no way out of the house without the escape of cobwebs," he said. "Included in my beard."
Not only spiders, other animals are also falling from the sky. One of them, a toad. It's a fact: the frog was showered Odzaci in Serbia in 2005. Also there is a rain of fish in the area of ​​barren Lajamanu, Australia in 2010. Also the small frog rain in Nanao and Hakusan in Japan in 2009. However, the exact cause of the incident is unknown.

Initially suspected that the act of birds. Meanwhile, the scientists are skeptical about the animal rain. However, there is one simple explanation by French physicist in the 19th century: that the strong winds lifted and then dropped the small animals that.

A slightly more complex theories involving the 'whirlwind' - a tornado that crossed the pond or lake, sucking water animals. The fish can be drawn by the vortex and dropped anywhere pickaxe running out of power. *** [EKA | FROM VARIOUS SOURCES | LIVESCIENCE]
