No, joro spiders cannot fly. However, young joro spiders can travel through the air using a process called “ballooning.” Spiderlings release a silk thread that is caught by the wind, carrying them to new locations. Depending on air currents, ballooning can potentially transport young spiders long distances. The spread of the spiders from Georgia to neighboring states is thought to be the result of ballooning spiderlings as well as accidental human transport.
