Meet Vespa mandarinia

From CNN:

Killer hornets sting at least 19 people to death in China, nearly 600 stung
At least 19 people have been stung to death by hornets -- which may include the world's largest hornet species Vespa mandarinia -- in China's central Shaanxi province in the last three months, according to the city government of Ankang, the apparent epicenter of a recent spate of fatalities and injuries.

A total of 583 people in the area have been stung by hornets since July 1, say city officials. Seventy victims are still recovering in hospitals.

Chen Changlin was hospitalized after being attacked by hornets, while harvesting rice last week.

"I ran and shouted for help, but the hornets chased me about 200 meters, and stung me for more than 3 minutes," he recounted to the state-run China Youth Daily.

Chen said hornets had first swarmed a woman and child working nearby, who then ran towards him. Both later died from the hornets' toxins.

"The more you run, the more they want to chase you," said another victim, whose kidneys were ravaged by the venom. When he was admitted to the hospital, his urine was the color of soy sauce, according to local reports.

Good thing it can't happen here - Oh. Wait. From the Arlington Heights, IL Arlington Cardinal:

Deadly Asian Giant Hornet Spotted in Arlington Heights, Illinois: Not Cicada Killer Wasp
Wasps, hornets and bees are in the news this summer. Last week bees swarmed Des Plaines Fire Department firefighter/paramedics as they rescued a man with an ankle injury about 5:54 p.m. on July 25, 2012. The firefighter/paramedics and their patient were stung by the bees as the victim was rescued up an embankment near Golf Road and River Road.

Sunday, an Asian Giant Hornet or Japanese Giant Hornet (Vespa mandarinia) was spotted at a residence west of St. Viator High School. The insect was at least two inches long and as thick as a human thumb. It had a wide orange-yellow head with large eyes, and distinct yellow-orange and brownish-black bands on its body � like a bee. The Asian Giant Hornet patrolled around a house in the front yard � occasionally hovering and landing on shrubbery. The Asian Giant Hornet studied a yellow-jacket nest that was recently destroyed with Raid wasp spray on the property. Yes, the giant hornets attack Yellow Jacket nests.

A forum on DSLReports.com Need to kill Asian Hornets and comments on a BadSpiderBites.com Giant Hornet article includes reports of Asian Giant Hornets in Alabama, California, Georgia, Illinois, Indiana, Iowa, Kentucky, Louisiana, New Hampshire, New Jersey, New York, North Carolina, Ohio, Oklahoma, Pennsylvania, Tennessee, Texas, Vermont, Virginia, and West Virginia. One of the pictures from a contributor from Tennessee shows a European Hornet. Last Fall posters reported aggressive infestations in recent years. In Georgia a poster reports he doesn�t go a day without seeing one of the giant hornets. One poster reports the insects flying into lights at night, and an infestation in a chimney with about 200 hornets getting inside the house. Many posters scoff at the comments that the insects aren�t aggressive. Some posters report that the large hornets are not affected by wasp/hornet spray.

Yikes!
