An invasive hornet that kills honey bees has been spotted in Britain for the first time, experts have confirmed.

The Asian hornet was found near Tetbury, Gloucestershire. Work is under way to find and destroy its nests. The Department for Environment, Food and Rural Affairs (Defra) has set up a three-mile (5km) surveillance zone. Defra said it had been anticipating the hornets' arrival "for some years" and had a "well-established protocol in place to eradicate them". The Asian hornet (Vespa velutina), which is up to 2.5cm (1in) long, is now common across Europe after being accidentally introduced to France in 2004 in a shipment of pottery from China. In the summer, the non-native species was discovered in the Channel Islands of Jersey and Alderney for the first time.

Image by PA Nicola Spence, from Defra, said: "It is important to remember they pose no greater risk to human health than a bee, though we recognize the damage they can cause to honey bee colonies. "That's why we are taking swift and robust action to identify and destroy any nests." A Defra spokesman said, the hornet found in the Tetbury area had been killed and was undergoing DNA testing to establish how it arrived in the UK. Meanwhile, bee inspectors are using infrared cameras and traps in a bid to locate and destroy any nests in a three-mile area radius around the initial sighting.
