15-mile-long cloud of ladybugs over California

“15-mile-long cloud of ladybugs over California appears on weather radar
It turns out a massive cloud of ladybugs, called a bloom, measuring 10 miles wide and 15 miles long was flying around above 5,000 feet elevation.
"He said it's an annual bloom that happens around this time of year," says Moede.
In California, the beetles are known to winter in the Sierra and gather in huge masses in valley areas in the spring to feed and mate, usually in the same places year after year.”

That's because the Californians don't vacuum their forests, like the Finns do.
