Valerie Castro (00:00):
If you have a fear of spiders, this venomous flying arachnid will send you running.
Speaker 2 (00:06): Oh, no, I got to go. No. Mm-mm.
Valerie Castro (00:09): And experts believe the Joro spider could descend on the East Coast later this year. The brightly-hued bug native to East Asia first arrived on US soil years ago. A leading theory suggests the critters were unintentionally transported here via cargo shipments and personal travel for settling in Georgia.
Jose Ramirez-Garofalo (00:28): The climate here actually mimics their habitat in their native range, so it's really, really similar. So, they can exist from the southeastern US all the way north into Canada.
Valerie Castro (00:39): They'll be hard to miss.
Speaker 4 (00:41): They are quite large.
Valerie Castro (00:43): With a leg span of up to four inches and the ability to fly by releasing silk threads into the air, reminiscent of this scene from Charlotte's Web.
Video (00:52): Goodbye. Goodbye. [inaudible 00:00:54].
Valerie Castro (00:54): But this is not fiction.
Jose Ramirez-Garofalo (00:56): Across the Eastern US, they're probably here to stay for the long term.
Valerie Castro (01:00): They might look scary, but experts say they don't pose any real risk to humans and pets, except for maybe some itching and irritation if bitten.
Speaker 4 (01:08): They are not notoriously aggressive.
Valerie Castro (01:10): They feed mostly on yellow jackets, mosquitoes, stink bugs, and that invasive species, the spotted lanternfly. While the Joro is also considered an invasive species, experts say, if you do see one, it's okay to leave it alone.
Jose Ramirez-Garofalo (01:25): There are a lot of native spiders that look almost identical to Joro spiders, so we definitely don't want to encourage people to start squashing them, because they could be killing native species.
