Asian giant hornets

'Murder hornets' land in the US for the first time

The 2-inch long Asian giant hornets have landed in the US for the first time, spotted on the west coast.

Multiple stings are deadly to humans and in their "slaughter phase" the hornets destroy honeybees, whose bodies they feed to their young.

Scientists are now on a hunt for the hornets, hoping to eradicate the species before they wipe out US bees.

Though they typically avoid people, in Asia, "murder hornet" stings are thought to cause as many as 50 human fatalities a year, according to the New York Times.
