A cockroach stowing away on a plane has gone viral after a passenger filmed it crawling inside a window.

The passenger, identified only by her last name as Guo, was flying in China from Ningbo, Zhejiang to Xishuangbanna, Yunnan on Wednesday when she said she saw a large cockroach in the window next to her, per local outlet Jimu News.

Guo thought the roach would only stick around for about "two minutes," and said she didn't tell any flight attendants about it, Jimu News reported.

"I didn't expect it to still be there after flying 3,000 kilometers. But I couldn't tell if it's outside the window or in the window's inner layer," Guo said.

In a video shot by Guo, the roach can be seen wiggling up and down while the plane cruises above the clouds.

The airline Guo was flying with was not named, but Jimu News wrote that a representative of the carrier confirmed the cockroach in the video was crawling between the window's layers of glass.

The staff said it was likely the roach was in the aircraft's cargo or luggage hold, and then climbed up to the window.

In an interview published by Boiling Point Videos, Guo said she found the cockroach "very entertaining" and spent the flight observing the unlikely passenger.

Guo's video went viral on Weibo, China's version of Twitter, and posts on the topic were viewed over 120 million times, per data seen by Insider.

"They can even survive above 10,000 meters?" one person commented with a crying emoji.

"As expected of the strong roach," another person wrote.
