This unusual sight was filmed along the Soreq creek near Jerusalem.
Long-jawed spiders spinned huge cobwebs, transforming the creek into a Halloween landscape, glistening in the sunshine.
According to scientists, this giant web phenomenon was triggered by treated sewage full of nutrients that promoted the proliferation of mosquitoes.
The insects are a source of food for spiders, which then reproduce in multitudes covering part of a forest in a giant web.
Colder temperatures to come, however announce the end of mosquitoes and thus of the spiders and their giant web.
