The species was identified as arachnids as Anelosimus eximius, which is extremely rare in the spider world as it is a social spider. They are usually in trees during the day and in the late afternoon and early evening construct giant sheets of webs, in order to trap insects. Marta Fischer, a biologist who specializes in spiders at the Pontifical Catholic University of Paraná, examined the picture and said that the phenomenon is normal and occurs mainly in the cities of São Paulo.

‘This type of spider is known to be quite social,’ she said.

There are  around 40,000 species of spiders around the world – but only 23 species are scattered around the world that are known to swarm, like ants or bees.

If strong winds come along, the web may detach from its anchors, carrying the spiders and their ruined home to new sites where they appear to ‘rain down.’

These clusters and flocks of spiders signify nature’s innate principle that in order to co-exist one has to be united and democracy has to be practiced in place of anarchy. 

Humans, a relatively younger species need to take time to realize and practice that.
