Weird news - massive swarm of ladybugs

Sometimes we come across natural behavior that seems incredible, and weird in some ways. The mass movement of animals is something that happens in many species, but when we come across it, it is an awe-inspiring experience. In earlier times, before man intervened in the environment, there were vast herds of large animals moving across the land (these were disrupted because of man settling in there, or shooting many of them), and in the skies, there are these huge movement of birds or insects as a part of their migration. Most of these are not seen now, and the ones that are seen are seemingly so out of the ordinary and incredible that they become news, such as this movement of ladybugs over California (link to article):

A huge blob that appeared on the National Weather Service’s radar wasn’t a rain cloud, but a massive swarm of ladybugs over Southern California. Meteorologist Joe Dandrea says the array of bugs appeared to be about 80 miles (129 kilometers) wide as it flew over San Diego Tuesday. But Dandrea tells the Los Angeles Times that the ladybugs are actually spread throughout the sky, flying at between 5,000 and 9,000 feet (1,525 and 2,745 meters), with the most concentrated group about 10 miles (16 kilometers) wide.
