A thick swarm of thousands of bees suddenly showed up at a Mexican restaurant in Florida and inexplicably began spiraling in a "tornado pattern," according to Local 6 News.

Diners at Oxie's in DeLand at first thought the huge cloud in the sky had formed Thursday because a rainstorm was coming.

But they soon fled to their cars in fear when they realized the cloud was actually a mass of bees — and the insects seemed to be taunting customers.

"It was scary," restaurant owner Oxie Ochiana told Local 6. "I was panicking. I didn't know what to do."

Bee experts said the insects were since resting in a tree in two giant cone-shaped formations, and would likely be gone within 24 hours. Ochiana said he called to get the bees removed.
