On Wednesday evening, the National Weather Service in San Diego posted a GIF showing a large cloud that had shown up on its radar in the San Diego County area. It wasn’t weather; it was a bloom of ladybugs. The Los Angeles Times reported that the swarm was about 80 miles long by 80 miles wide, with a concentrate mass 10 miles wide.
The bloom of ladybugs was flying at between 5,000 and 9,000 feet in altitude. According to SFGate, a ladybug blooms occur every year as the beetles move from the Sierras where they winter in order to find food.
