Mumbai, June 8: The Joro spider or Trichonephila clavata is an East Asian native arachnid recognised for its striking appearance and significant size. Characterised by vibrant yellow, blue, and red colouration, the female Joro spider can reach up to four inches in leg span, making it one of the largest spider species in its native regions. Its intricate, golden-hued webs are both strong and expansive, often spanning several feet.

Earlier in 2024, sightings of the Joro spider were reported across various states in the southeastern US, including Georgia, Alabama, North Carolina, South Carolina, and Tennessee, extending to Oklahoma, West Virginia, and Maryland. This rapid spread observed this year has sparked curiosity and concern among residents and scientists alike. Let's answer some of the most common questions about these fascinating spider species. What Is Spider Rain?

Where Are Joro Spiders From?

Joro spiders originate from East Asia, with their natural habitat encompassing regions in Japan, Korea, China, and Taiwan. Recently, these spiders have made their way to the southeastern US, first being spotted in Georgia in 2014. It is believed that they arrived accidentally via shipping containers.

Can Joro Spiders Fly?

Joro spiders cannot fly in the traditional sense. However, they can travel considerable distances through a behaviour known as "ballooning." In ballooning, spiders release silk threads into the air, allowing them to be carried by the wind. This method of aerial dispersal enables them to colonise new areas. Venomous Spider That Can Cause Long and Painful Erections Spotted in Austria Supermarket; Leads to Temporarily Closure of Store.

How Venomous Is the Joro Spider?

The venom of the Joro spider is primarily used to subdue its prey, which consists mainly of small insects. While their venom is effective against their prey, it is not considered dangerous to humans. Most reactions to their bites are mild, similar to a bee sting.

Can Joro Spiders Kill Humans?

No, Joro spiders cannot kill humans. Their venom is not potent enough to cause significant harm to humans. While their bites may cause minor discomfort or allergic reactions in some individuals, they are not lethal.

Do Joro Spiders Bite?

Joro spiders are generally not aggressive towards humans and will only bite if they feel threatened. Bites are rare and typically occur if the spider is accidentally handled or trapped against the skin. The bite may result in mild pain, redness, and swelling, but it is not dangerous.

The Joro spider's rapid expansion in the southeastern US has undoubtedly captured the attention of both the scientific community and the general public. Despite their striking appearance and large size, these spiders pose minimal threat to humans. Understanding their origins, behaviours like ballooning, and the mild nature of their venom can help alleviate concerns and promote coexistence with these fascinating arachnids. As they continue to establish themselves in new territories, ongoing research and public awareness will be crucial in monitoring their impact on local ecosystems and biodiversity.
