The 'rain of spiders' was filmed in Santo Antonio da Platina by a local resident Erick Reis.
"I was shooting an engagement party for some friends of mine and I saw the spiders when I was leaving, in the late afternoon. I've never seen anything like it before", Erick said that the spiders were trapped in webs and moved a lot.
