The Nevada desert that will host the annual Burning Man festival later this month is overrun by thousands of flying, biting, crawling bugs, according to a festival organizer. "They're everywhere. They bite. They crawl all over you. They get up and in you," said the organizer, John Curley.

The bugs are so pervasive that one went up a woman's t-shirt and settled in her bra, while others weaseled through a welding mask and made a home for themselves around another woman's eyes.

"What's going on? We don't know. We don't know how the little critters survive in the heat and the sun. All we know is that if you pick up some wood, you're likely to uncover hundreds or thousands of the things," Curley wrote.
Burning Man, a weeklong arts festival that attracts tens of thousands of people to the remote area of Nevada, starts Aug. 30.
