In 2010 a monsoon hit Pakistan that caused the rivers to swell and insects to run for cover. The strange anomaly was captured by aid worker Russell Watkins, a multimedia editor with the U.K.'s Department for International Development (DFID) in the Pakistani village of Sindh."There wasn't a scientific analysis of this being done. Anecdotally, I think it was pretty much any kind arachnid species, possibly combined with other insects," he toldNational Geographic. It was noted that because the flood waters took so long to recede, spiders who had sought asylum in the trees had just begun to spin weaves. Locals said they had never seen anything like it before.
