Citizens of the Chinese province of Liaoning were told to find shelter after it started to rain worms.

A viral clip showed the area apparently being showered with little worms, which were splattered all over cars.

In the video residents could be seen covering themselves with umbrellas as they go along with their routines.

While the cause of the phenomena is unknown, the scientific journal Mother Nature Network suggested that the animals were dropped after being swept up by heavy winds.

The periodical also noted that this type of occurrence happens after a storm when insects are caught up in a whirlpool.

Another theory suggested that the worms were actually poplar flowers — a tulip tree whose blooms resemble the squirmy insects.

Viewers were stunned by the city’s current problem, with one person on Twitter stating: “These are not worms or animals, but flower stalks dropped from trees.”

Someone else claimed that the video was fake and looked like a prank.

Another tweeted, “If I was just minding my business on a casual day in China and it started raining worms?? I’d just die.”

A similar odd event occurred last December when it was believed that iguanas would rain down from trees in Florida due to colder temperatures.

“They slow down or become immobile when it’s below 40,” WFTV meteorologist Brian Shields posted on Twitter last winter. “They may fall from trees, but they aren’t dead.”

The incident is reportedly not uncommon when colder weather hits the Sunshine state. When temperatures drop, the reptiles become stiff and tumble to the ground.
