Detailed Analysis :
The description that comes with the images claims that they depict webs woven by millions of spiders that escaped to the safety of trees in response to widespread and prolonged flooding in Pakistan during 2010.
The photographs are genuine. A March 2011 report on the National Geographic website notes:
Trees shrouded in ghostly cocoons line the edges of a submerged farm field in the Pakistani village of Sindh, where 2010’s massive floods drove millions of spiders into the trees to spin their webs.
Beginning last July, unprecedented monsoons dropped nearly ten years’ worth of rainfall on Pakistan in one week, swelling the country’s rivers. The water was slow to recede, creating vast pools of stagnant water across the countryside.
And a March 2011 article published on Wired Science also reports on the phenomenon:
The unprecedented flooding in Pakistan in the latter half of 2010 disrupted the lives of 20 million people, but it also affected the country’s arachnid population.
With more than a fifth of the country submerged, millions of spiders climbed into trees to escape the rising floodwater. As the water has taken so long to recede, the trees quickly became covered in a cocoon of spiderwebs. The result is an eerie, alien panorama, with any vegetation covered in a thick mass of webbing.
