Be On The Lookout For A New Invasive Species Of Spider In Iowa This Year

The news reports are both fascinating and terrifying - a new invasive species of spider is crossing the ocean to make its appearance in the United States. While it's starting on the east coast, many residents of Iowa are wondering - should I be keeping an eye out for the Joro Spider in my backyard? Here's everything you need to know about this distinctive arachnid.

Trichonephila Clavata is one of the largest spiders out there, commonly found in Japan, China, and Korea. But it's more commonly known as the Joro Spider.

At up to 25 millimeters at its largest and with a distinctive yellow color, it can be identified from a large distance - and many people give it a wide berth.

It behaves similarly to other spiders, lurking in corners to hunt its prey and spinning webs.

But what makes it stand out are its webs - long and strong, they're often seen covering power lines in Japan and can be used to make a durable silk.

If you see a Joro Spider, the odds are it will be a female - they're over twice the size of the tiny and harmless males.

They're already in the southeastern United States and are expanding their range - partially by "parachuting" when their large webs are carried by the wind.

They might look intimidating, but the spiders aren't aggressive and don't have strong venom. Their jaws aren't large enough to pose a danger to humans.

In fact, they might be helpful - their favorite food is insects, so they may just get rid of some household pests.

The Joro Spider may not be in Iowa - yet - but the Hawkeye State has no shortage of its own unique wildlife. Let us know about your encounters in the comments section.
