According to experts, the spiders built a giant cobweb above ground to catch mosquitos overnight.
Residents in the rural area of southern Minas Gerais in Brazil woke up to warm weather with a bit of spider raining down the sky. While parts of the US dealt with snow last week, one town in Brazil experienced something that doesn't typically show up in your regular weather forecast - airborne spiders.
Fourteen-year-old João Pedro Martinelli Fonseca told a local newspaper he saw the sky covered with black dots while traveling with his family to his grandparents' farm in Espírito Santo do Dourado, about 155 miles north-east of São Paulo, according to the Guardian.
His grandmother Jercina Martinelli, told local paper Terra Do Mandu: "There were many more webs and spiders than you can see in the video".
"There were many more webs and spiders than you can see in the video", she shared. "We've seen this before, always at dusk on days when it's been really hot". The intricate and fine web is nearly invisible to the naked eye, which results in the visual seen in the video.
While the spiders appear to be floating, they're actually suspended in a giant web.
The movie, directed by Frank Marshall, is based on a foreign spider finding its way to a small town in America and which then creates a species of deadly arachnids. The spiders, belonging to the parawixia bistriata species, weave a web so fine it is almost impossible for the human eye to see - and that gives the illusion that they are floating in air. The spiders feast on their prey in the morning before retreating to the undergrowth.
Skin-crawling footage shows a sky filled with spiders in Minas Gerais, south eastern Brazil, as the eight-legged creatures weaved a giant ceiling-shaped web.
Some have been quick to share just how much they are scared of the creepy crawlies.
