While there are no spiders that fly as say a bird for example, some spiders are known to engage in a behavior called “ballooning,” which is often misconstrued as flying. Ballooning is a form of spider transportation in which a spider will climb to a high point, release a silk thread into the air, and let the wind carry itself away. This behavior allows spiders to travel great distances, even crossing bodies of water or mountain ranges.

While ballooning might look like flying at first glance, it’s important to note that the spiders are not actively flying like birds or insects with wings do. Instead, they are passively drifting in the wind. So while spiders don’t technically fly, they can still travel through the air using this method.

It’s also worth mentioning that only certain species of spiders use ballooning as a method of travel. Not all spiders have this ability or exhibit this behavior and its usually very small spider species as well.
