In the strange but true department, Brazilian news-site G1 is reporting that web designer Erick Reis, 20, filmed this shuddersome 'spider shower' last Sunday at a party he was attending in Santo Antonio da Platina, a small town in the southern state of Parana.

Reis told G1, 'I was shooting an engagement party for some friends of mine and saw the spiders when I was leaving in the late afternoon. It was an amazing situation. I'd never seen anything like it and could hardly believe what I was seeing.'

After looking at the video, Marta Fischer, a biologist from a local university who specializes in the study of arachnids, said that the phenomenon is normal and is observed most often in the Brazilian state of Sao Paulo.

'These are spiders of the Anelosimus Eximius species, also known as social spiders,' she explained. 

'They usually stay in trees during the day and in the evening and early night they build a sort of spiderweb sheet. Each one makes its own part and then they join them all together. The objective is to capture insects. During the day they destroy the webs to prevent the  birds from doing it.'

Although the biologist gave assurances that this particular bug's venom is not poisonous to humans, I am sure most of us would rather avoid not only a bite from them, but even the sight of them.
