Information leaflet on Vespa velutina

Vespa-velutina-flyer-1st-pageThe Asian predatory wasp (Vespa velutina), also known as the Asian Hornet or yellow-legged hornet, is a species of hornet indigenous to Southeast Asia, particularly the tropical regions, from Northern India, Pakistan, Afghanistan, Bhutan, China, Taiwan, Burma, Thailand, Laos, Vietnam, Malaysia, the Indo-Chinese peninsula and surrounding archipelagos.

As an invader in Europe the hornet has appeared in France, Spain, Portugal. Further invasions are expected in various countries including much of Europe.

As it is currently spreading from South towards the North of France, we expect this wasp species to arrive in Luxembourg quite soon. This is why a leaflet was produced to enable people and especially bee keepers to identify the species and report its presence to the authorities.
