The female Joros ensnare prey, including unlucky males, using large golden or yellow-hued orb webs.<\/p>\n<p>Perhaps most shocking is how well the species has adapted to life in US cities. <\/p>\n<p>According to a study by the <a href=\"https:\/\/www.mdpi.com\/2813-3323\/2\/1\/4\" target=\"_blank\" rel=\"noopener nofollow\">University of Georgia\u2019s Odum School of Ecology<\/a>, the species tolerates the urban cacophony better than other animals, which, along with preternatural cold tolerance, allows the critter to proliferate in Southeast towns.<\/p>\n<p>The team tested the species\u2019 resilience by simulating prey sounds with tuning forks by the side of the road, discovering that the Joro was unaffected by traffic and other urban factors.<\/p>\n<p>\u201cFor some reason, these spiders seem urban tolerant,\u201d noted study lead Andy Davis, adding that the webs are everywhere in the fall, including next to busy roads.<\/p>\n<p>Joro spiders, while venomous, pose no threat to people, experts say. <\/p>\n<p>\u201cThere have been no documented fatalities, nor any notable\u00a0medically significant bites,\u201d Jos\u00e9 R.
