Giant spider webs, spun by long-jawed spiders (Tetragnatha), cover sections of the vegetation along the Soreq creek bank, near Jerusalem on November 7, 2017. Science and nature combined to create the unusual sight: the Soreq creek largely contains treated sewage full of nutrients that promote the proliferation of mosquitoes that serve as a source of food for spiders, which then reproduce in multitudes.
