NEW SOUTH WALES, AUSTRALIA – Spider shower took place in a town Goulburn, in New South Wales, approximately 195 km south-west of Sydney, where millions of baby spiders rained down from the sky and blanketed the countryside with their webs.
This phenomenon was quiet natural as Australian Museum Naturalist Martyn Robinson said a migration technique called “ballooning” could explain the phenomenon.
During a “ballooning” event, the spiders will climb up as high as they can, stand on raised legs with its abdomen pointed upwards and release several silk threads into the air. These strands form triangular shaped parachutes that allow them to be carried away by the wind hundreds of miles to a new territory. In windless conditions, the Earth’s static electric field may also provide lift.
The vast majority of these spiders die during the journey, eaten by predators or killed by harsh weather conditions. But a small fraction survives to set up a new colony. Once they land, the spiders disappear into the ground.
According to a resident Ian Watson ,”The whole place was covered in these little black spiderlings and when I looked up at the sun it was like this tunnel of webs going up for a couple of hundred meters into the sky.”
