Spiders rained from the skies in Brazil this weekend.
Footage was captured of hundreds of the eight-legged creatures spiralling through the air and dangling from telephone poles in the southern Brazilian town of Santo Antônio da Platina.
Brazilian news channel G1 quotes biologist Marta Fischer as saying the occurrence is "normal".

Fischer, who specialises in the study of spiders at the Pontifical Catholic University of Paraná identified the arachnids as Anelosimus Eximius, which are "also known as social spiders."
She added: "They are usually in trees during the day and in the later afternoon and early evening construct a sort of sheet web.
"Each makes his and then they come together. The goal is to capture insects."
Anelosimus Eximius inhabits tropical environments throughout South America. Scientists have determined that social spiders work in teams to catch much larger prey than otherwise possible.
The spiders are apparently not venomous to humans. Oh so that's alright then.
