It turned out that the “big mystery shadow” caught by the weather radar was actually a large group of ladybirds. The shadow that meteorologists insisted 'it is not a cloud' seems to have a tremendous size of 128km square.

The National Weather Service, located in San Diego, USA, captured a huge cloud-like shadow on the night of June 4, 2019. Subsequent research has revealed that this shadow was not a cloud but a ladybird.

According to meteorologist Joe Dandrea, hordes of ladybirds appear on the radar as 80-mile (about 128 km) masses, flying 5000-9000 feet (1.5-2.7 km) from the San Gabriel Mountains to San Diego About.

Having confirmed the shadow of the mystery in the radar, Dandrea instincted that 'it's not a shadow of a cloud' and asked the observer of the place where the mysterious object was generated, 'Can't you see something?' And what the observer said was that the answer 'I saw something like a small point flew away' was obtained.

According to the IPM program of the University of California, there are approximately 200 types of ladybirds in California, but it is unclear at the time of writing which type of ladybird caused this phenomenon.
