Whole trees covered with spiders’ web

Trees covered in ghostlike cocoons line the edges of a submerged farm field in the Pakistani village of Sindh, where 2010's massive floods drove millions of spiders and possibly other insects into the trees to spin their webs.

Beginning July 2010, 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.

Locals said that they’d never seen anything like it before. It was said to be a slow motion type of disaster. Spiders and other insects sought refuge in the trees. There were so many that entire trees became massive cocoons for them. They spun webs that covered the trees as a whole. People standing under the trees had lots of little spiders falling down on their heads.
