Meteorologists in southern California June 4, 2019 fixed on a clear day on the radar of the National weather service giant blur. According to the researchers, it arose due to the unprecedented large swarm of ladybugs from tens of millions of animals, which occupied an area of about 16 square kilometers. However, the exact cause remains unknown. This publication reports Science Alert.

Experts believe that the “cloud” formed by the species Hippodamia convergens, although in California there are about 200 species of ladybugs. Insects, probably flying at a height of 1.5-2.7 km. This behavior is due to normal annual migration, but at the time Roy appeared in an unusual time of the year and was too big. In the cold season they migrate to wintering, and spring back to begin the hunt for aphids.

Scientists believe that unusually wet and warm winter has contributed to the survival of a large number of beetles. However, it is not clear what factors played a role in the emergence of the swarm. Ladybugs appeared a little later than usual.

However, some experts, including entomologists and ecologists doubt the version that the cause of the spots on the radar were just ladybugs. The air temperature was not optimal for insects, and the insects usually form swarms with a population of several thousand individuals, not tens of millions.
