Trees cocooned in spiders webs, an unexpected side effect of the flooding in Sindh, Pakistan

An unexpected side-effect of the 2010 mega-flood in parts of Pakistan was that millions of spiders climbed up into the trees to escape the rising flood waters.


Because of the scale of the flooding and the fact that the water took so long to recede, many trees became cocooned in spiders webs. People in this part of Sindh had never seen this phenomenon before - but they also reported that there were less mosquitos than they would expect, given the amount of stagnant, standing water that was around.


UK aid - in response to the Pakistan floods - helped millions of survivors return home and rebuild their lives.
