During any average summer day, there may be literally billions of insects flying in the sky directly over your head.
What bugs lack in overall size they more than make up for in the altitude at which they fly. Lady bugs and other beetles regularly fly thousands of feet up, gypsy moths have been found 10,000 feet in the air, and even higher than that are the spiders clinging to pieces of silk flying 12,000 feet up.
But all of those are heights are dwarfed by a single termite that was found at 19,000 feet up, which is just under the height of Mount McKinley in Alaska.
On any given summer day, you can look up and know that there are billions of bugs passing directly over, flying along different bug highways of varying altitudes. It sounds like a Pixar movie.
Here's a wonderfully produced video that explains it all:
