Asian hornet may have become established in UK, sighting suggests

Predatory species, which poses huge danger to bee populations, spotted on 11 March, indicating winter stay

Asian hornets may have become established in the UK after the earliest-ever sighting of the predatory insect was recorded by the government this month.

This is a dangerous development for Britain's bee population and could have a knock-on effect on agriculture that needs the pollinators, because once hornets are established it is almost impossible to eliminate them.
