The Asian or “Yellow Legged” Hornet, Vespa velutina, is spreading in Europe and in 2016, reached the UK. First found in France in 2004, perhaps imported in a shipment of pottery from Asia, the Asian Hornet has adapted to European climate. This hornet, like all wasps, is a predator. Most worrisome is the ability of the Asian Hornets to enter bee hives, attack and kill bees. Hornets have been known kill sufficient bees to eliminate colonies.
