The Asian hornet was confirmed for the first time in Lot-et-Garonne in the South West of France in 2005. It was thought to have been imported in a consignment of pottery from China and it quickly established and spread to many areas of France. It is reported to be causing many problems for both beekeepers and biodiversity in the country. The hornet can predate on colonies, causing significant harm. All beekeepers should be on the look out for this hornet. Vespa velutina is smaller than our own native European hornet Vespa crabro (see the information sheets that should help with identification). Vespa velutina should not confused with the Giant Asian hornet, sometimes referred to as the "Japanese hornet" Vespa mandarinia.
To protect bees from invasive threats it is important for all beekeepers in England, Scotland and Wales to sign up to BeeBase.
If you think you have seen an Asian hornet, please notify the GB Non Native Species Secratariat alert email address at immediately.
You can also send a suspect sample to the NBU laboratory for examination if possible. Use a suitable sturdy container (cardboard rather than plastic) and provide as much detail as possible about the hornet and where you found it. See 'How to Send Samples into the Laboratory' page. Digital photographs are also very useful to help with identification.
The message to Beekeepers from the NBU is as follows:
There are a number of links to useful information on the hornet, plus details of how to distinguish between the native hornet Vespa crabro and Vespa velutina. Although they are a similar size, a very distinguishing characteristic between the two is the dark brown thorax, hence the name "nigrithorax".
To help distinguish between the many species of Vespa species, the French Museum of Natrual History have produced an Identification Information Sheet
In the event that Asian hornets arrive in GB:

BeeCraft magazine published a detailed article covering the lifespan, habitat and spread of the Asian hornet through France. Please see the article 'Vespa velutina – The Asian Hornet' which also covers the impact on agriculture and honey bees. Follow-up articles have been produced in September and October 2011. These can be viewed here. Thanks to Bee Craft for allowing us to provide this article.
Biologist Magazine published an article in May 2009 'A foreigner in France: the Asian hornet' written by Marie-Pierre Chauzat of the French Food Safety Agency and Stephen Martin from the University of Sheffield. We thank the authors for allowing us to attach this piece.
There is also an article in 'Aliens- The Invasive Species Bulletin' (Issue No 31, 2011) titled: Monitoring and control modalities of a honeybee predator, the yellow-legged hornet Vespa veluntina nigrithorax (Hymenoptera: Vespidae)

The Great Britain Non-Native Species Secretariat website provides a great deal of information about invasive non-native species, including this Asian hornet. The wesbite covers the wide ranging work that is being done to tackle invasive species across Great Britain and provides tools to facilitate those working in this area.
