In Southern California, meteorologists realized there was something unusual on the radar, on Tuesday. The tiny specks that appeared on the screen turned out to be a swarm of ladybugs, or what's known as a ladybug bloom.
The National Weather Service meteorologist, Joe Dandrea, told The Los Angeles Times that this bloom was about 80 miles by 80 miles. The colossal bloom was flying high, at around 5,000 to 9,000 feet in the air.
California is home to many different types of ladybugs, totaling nearly 200 different species, which made figuring out who the culprit in the sky was a challenge. The convergent lady beetle turned out to be the species responsible for this scare. Lady beetles are very similar to your average ladybug—they're longer than some and have reddish, orange-ish forewings with up to 13 spots. But not all of them have spots.
Ladybugs migrating in massive swarms are not uncommon, but this size swarm may be a new record high.
The LA Times also reported that this is not a strange occurrence. Every spring, when the temperature begins to reach 65 degrees or above, this particular species of ladybugs mates before migrating from the Sierra Nevada to the valley to lay their eggs and be surrounded by a plethora of food.
Don't worry, the ladybugs won't be gone for long. Once they eat all of the aphids down in the valley, they will migrate to higher elevations and start the process all over again.
