Spiders Use Earth's Electric Field to Fly Hundreds of Miles - The Atlantic
"Spiders have no wings, but they can take to the air nonetheless. They’ll climb to an exposed point, raise their abdomens to the sky, extrude strands of silk, and float away. This behavior is called ballooning. It might carry spiders away from predators and competitors, or toward new lands with abundant resources. (..)
Every day, around 40,000 thunderstorms crackle around the world, collectively turning Earth’s atmosphere into a giant electrical circuit. The upper reaches of the atmosphere have a positive charge, and the planet’s surface has a negative one. Even on sunny days with cloudless skies, the air carries a voltage of around 100 volts for every meter above the ground. In foggy or stormy conditions, that gradient might increase to tens of thousands of volts per meter. Ballooning spiders operate within this planetary electric field."

Spiders Use Earth's Electric Field to Fly Hundreds of Miles - The Atlantic
Electrostatic charges in the air can and are sensed by spiders who spin long filaments during gentle breezes to fly, sometimes tens or even hundreds of miles. A pair of scientists recently proved that electrostatic charge alone is enough to buoy spider's silk. Previously it was thought that it was friction of the wind and silk that was solely responsible. It may be that the wind is more responsible for stretching out the silk and providing horizontal travel, while electric repulsion between the silk and the earth may be responsible for most lift.
