I actually pulled over in two different locations last year to watch this. 
I stop outside of El Centro, CA and Gila Bend, AZ to watch the Orange 
Sulphurs getting wiped out on Interstate 8. If they weren't getting hitting 
square by the windshields and grills. It was the vortex caused by the 
speeding car, and the bugs were lifted up and over the cars and smashed to 
the ground behind the cars.
