Spiders fly on the currents of Earth's electric field (2018)

Spiders don’t have wings, but they can fly across entire oceans on long strands of silk. For more than a century, scientists thought it was the wind that carried them, sometimes as high as a jet stream — in a process known as “ballooning.” A new study shows that the Earth’s electric field can propel these flying spiders too.
