Vatic Note: There are a billion and 5 reasons why we should watch the skies. Its a virtual separate planet from earth, just like under the sea is the same way. We miss out in many different ways and on many different levels when we do not take the time to examine our world on all three levels. Today this is about the world above us and this video only covers a portion of what is up there. Besides these, you also find flocks of birds migrating or simply enjoying a free glide on the winds and we miss out on magical figures created by our clouds, faces, animals, and other magical creatures and places, palaces etc. But best of all is the "BILLION BUG HIGHWAY"....... something a bit different, but also to remind us that under the banker system, who has time to know, see, or experience our world??? No one. Now that the bankers are gone per se and we are going to choose to live as we should have been doing all this time, we can enjoy such wonders that we did not know existed. Here is a video to show us so enjoy something different from the mudane and manmade and watch something created by nature. Who would have thought the wind had such an important job, huh???? Pay attention to the spiders and how they hitch a ride. Its a trip.

Step outside on a clear day this summer and look up. What do you see? Blue. And maybe a plane or a bird up there, but otherwise ... nothing. Or so you think. It turns out that right above you, totally invisible, is an enormous herd of animal life. There are so many creatures up there, they are so busy, so athletic, so tiny, that we had to fly up and give you a peek.

When British scientist Jason Chapman told us (listen to the radio piece or watch our video) there are 3 billion insects passing over your head in a summer month, he was talking about his survey in Great Britain. 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.
What Are They Doing Up There?
Sometimes insects and spiders need to leave where they are and go someplace else for food, for sex, for space. For a variety of reasons bugs disperse. You can see them launching themselves, says entomologist Matt Greenstone:
"They just stand straight up on their little back legs and just by doing that they can get part of their body up into this layer [of air] where it’s more turbulent and then, if you can get a ride on a parcel that's going up, you can get off the ground and then if you’re lucky you can get carried aloft."

How High Can They Go?
Writing in American Entomologist recently (Spring 2010 "Frequent Flyer Miles"), May Berenbaum says pilots have long known insects can fly very high.
"Beginning in 1926, Tanglefoot-coated slides were affixed to airplanes to collect insects, with famed aviator Charles Lindbergh contributing to the data-collection effort by carrying sticky glass slides on his 1933 flight crossing the Atlantic at 2,460 to 5,410 feet and over Greenland at 7,870 to 12,135 feet."
Now 12,000 feet is pretty high, but the all-time champ is, of all things, a termite!
In Berenbaum's article, she mentions a 1961 study by J.L. Gressit in which an insect trap was placed on a Super-Constellation airplane. That plane flew 116,684 miles sampling the air, catching whatever was up there, and, Berenbaum says, "the trap managed to capture a single termite at 19,000 feet." That's the record.

You wonder how a little critter can survive the wind, the cold, the absence of company. "Wind dispersal at great heights can be rough on insects," Berenbaum writes. And yet they are very tough. Of 1,610 insects captured by another team of scientists led by L.R. Taylor in 1960, 97 percent were alive and undamaged, 2 percent were alive and damaged, and 1 percent were dead. The flying corpse was, it turns out, a rarity.
If all this interests you, check out Insectopedia by Hugh Raffles, just published, whose essay on bugs in the air (Chapter 1) is how I bumped into this subject. Raffles (briefly), Berenbaum and Greenstone all appear in our radio story; Benjamin Arthur's animations are lovingly and meticulously (OMG, does he work hard) constructed (and he drew the heroic British mouse in an earlier post).
