What is a Joro Spider?

Joro spiders are an invasive species that was first discovered in Georgia in 2014 and has since spread to several counties. This spider species is larger in size than most species found in the U.S., giving them a threatening appearance. The Joro spider is known to travel via ‘ballooning,’ in which young spiders or spiderlings release a small strand of silk allowing it to move by catching onto an air current.
