There are more insects in the atmosphere than you’ll ever see. In fact, you don’t see them all because they fly really high. How high? NPR has an animated video with the surprising answers.

Closer to the equator, he says, the numbers should rise. He wouldn’t be surprised, for example, that in the sky over Houston or New Orleans there could be 6 billion critters passing overhead in a month.
