A mysterious blob picked up on National Weather Service radar over Southern California last week turned out to be a swarm of ladybugs measuring 80 miles by 80 miles wide. The so-called ladybug bloom was seen Tuesday at around 8 p.m., 5,000 to 9,000 feet over San Bernardino County, as reported by NBC News

According to Science Daily, ladybugs use pheromones to follow one another, making it possible to travel in large groups. Tuesday’s swarm, which was headed for the mountains and desert for the summer months, was visible to climatologists because of significant advancements in Doppler radar.

The ladybug bloom is the second major migratory event by insects to captivate SoCal in the past several months. In March, SoCal neighborhoods were dazzled by millions of “painted lady” butterflies heading north toward Oregon.
