Big Venomous Spiders From South Carolina Now Invading Other States
An invasive spider species is spreading…everywhere! We have South Carolina to thank for its big venomous spiders moving to other states. A study from Clemson University says Joro spiders are spreading beyond South Carolina and are expected to spread through most of the eastern U.S. and eventually the entire country. The spiders are large, brightly colored yellow and black and use their webs to travel in the wind. Whaaaaat??? I’m down with any of this ha!
The females have a bright, distinct color pattern.
They are typically black or dark brown with yellow, orange, or red markings on their abdomen. These markings give them a visually striking appearance. Making them more attractive to a mate. Joro spiders are also pretty big. How big? According to Wikipedia, Females reach sizes of around 1-1.5 inches (2.5-3.8 centimeters) in body length and a leg span of up to 4-6 inches (10-15 centimeters). Males are much smaller though. The males are also much smaller and less colorful than the females. They are often difficult to spot in the wild because they don’t build webs for capturing prey. (What kind of spider doesn’t make a web?)
The female Joro spider makes huge webs. Some of these webs can be a few feet wide and long. They make them in gardens and other open spaces. Have fun running through that thing!
The good news? Joro spiders are not known for being dangerous to humans. They’re venomous spiders, but researchers say they don’t bite humans or pets unless they are cornered. While they possess venom to immobilize their prey, their venom is not considered harmful to humans. Their bites are generally not medically significant for humans. I once heard the same thing about daddy long legs.
Good news on the venom front though! I got bit by a fire ant a few weeks ago, and that thing hurt like hell!
