It looks like something out of Harry Potter, but a real monster spider's web has been found in Lake Tawakoni State Park in Texas, USA. Apparently the web, stretching 180 metres, is the result of millions of spiders working together, to the mystification of park rangers.
The web is proving effective in controlling the mosquito population. Donna Garde, park superintendent, said that “There are times you can literally hear the screech of millions of mosquitoes caught in those webs.”
