Nature is full of surprising and sometimes terrifying phenomena. Case in point: this film of spiders seems to rain from the sky.
Shot in the Minas Gerais in southern Brazil, these spiders are Parawixia bistriata, a rare "social" spider working together to build giants, thin nets at the top.
And on the contrary of how it might seem, do not worry, they are not really raining from the top.
In reality, these harmless orb weavers are housed in a giant, thin net that is almost invisible to the naked eye, hunting for prey. At the end of the video you can see them moving on the web.
As apocalyptic as it may seem, this phenomenon is quite common in the area when the weather is hot and humid ̵
His grandmother Jercina Martinelli, told a local newspaper Terra Do Mandu : "In the video there were many more webs and spiders than you see before, always at dusk on days in which was very hot. "
Adalberto dos Santos, professor of biology specializing in arachnology at the Federal University of Minas Gerais The Guardian who Parawixia bistriata work together in the evening to build networks that can be up to 4 meters wide (13 feet) and often 3 meters
At dawn, they eat prey caught on the net during the night – small insects and sometimes even small birds – before passing the day hidden in the vegetation
The good news is that these spiders are harmless to human beings – indeed, they actually help us by getting rid of insects like mosquitoes and flies.
"They benefit us far more than they can harm us," said dos Santos. The Guardian.
