Wikimedia Commons Millions of bright yellow, hand-sized spiders are spreading up the US East Coast. The Joro spider, originally from East Asia, probably arrived in the US in 2013 via a shipping container. They “aren’t subtle,” Scientific American reported, with their four-inch leg span, black-and-yellow coloration and huge golden webs. But they’re also “shy and docile,” and not going to “hurt you … your kids [or] your pets,” a biologist said. Their march is “probably unstoppable” — as juveniles they float on the wind, like dandelion seeds, using a thread of silk. Scientists say they’re best left alone: If one takes up residence in your backyard, it will likely be there for months, so “give it a name. Show your kids … Show them what spiders do.” |
