 This insect is not in Ryedale, yet….

…but it has been found in Scotland and Devon !

Vespa velutina on cotoneaster – Mensignac

If you should find yourself in the Dordogne region of France, near the market town of Riberac, there is every chance you will see Asian hornets. Even if you do not, there is a pest control operation based there called allo-3D [11, Place Nationale, 24600 Riberac] that has displays of cut-through nests and a host of current information. Did you know for example, that in this part of France at least, nests have been found at ground level in old tunnels left by moles? Talk to Elodie Cornu who is a beekeeper, speaks beautiful English [and French] and has a wealth of knowledge on current management practices and control strategies.

These pictures were taken on cotoneaster flowers at Mensignac in the Dordogne, where 4-5 hornets were seen feeding on a regular basis. A specimen of the European hornet was also captured at the same site.

And this is what you can do if you catch one…bottled hornet

*** New App for IOS and Android systems ***

A new App is now available. It has been developed by, and for, the Department for Environment, Food & Rural Affairs [DEFRA]. It is designed to be easy to use and allows fast reporting of possible Asian hornet sightings.

The interactive app, developed by the Great Britain Non-native Species Secretariat and the Centre for Ecology and Hydrology, will also make it easier for people to judge whether an insect may actually be an Asian hornet; with pictures available of other insects that it could be confused with and helpful information about their size, appearance and the times of year they are most likely to be spotted.

Martin Smith, Public Affairs Manager at the British Beekeepers’ Association, said: This new app launched today by DEFRA is a welcome addition to current reporting methods that have enabled beekeepers and members of the public to report possible sightings. The key to containment is catching outbreaks as early as possible and allowing fast tracking of the insects back to their nest. We will certainly be encouraging all our 25,000 beekeepers to install the app and use it if they see what might be an Asian hornet near their hives.
The Asian Hornet Watch app is available to download from the Apple and Android app stores.


 

Species Alert [see nonnativespecies.org]

Vespa velutina, also known as the Asian hornet is an invasive non-native species from Asia. It arrived in France in 2004 where it spread rapidly. As a highly effective predator of insects, including honey bees and other beneficial species, it can cause significant losses to bee colonies, and potentially other native species.

The National Bee Unit confirmed a sighting of the Asian hornet in the Tetbury area of Gloucestershire in September 2016 – the first time the hornet has been discovered in the UK. The places it is most likely to be found are in southern parts of England or goods among which it could be accidentally imported [such as soil with imported pot plants, cut flowers, fruit and timber]. it is inactive over the winter.

RBKA will post news on occurrence and distribution in the UK as and when it is received. One of our members was actively involved in the recent reporting from Tetbury and the latest news will be available here!

What to look out for…

  • Vespa velutina queens are up to 3 cm in length; workers up to 25 mm [slightly smaller than the native European hornet Vespa crabro]
  • Entirely dark brown or black velvety body, bordered with a fine yellow band
  • Only one band on the abdomen: 4th abdominal segment almost entirely yellow/orange
  • Legs brown with yellow ends
  • Head black with an orange-yellow face
  • Vespa velutina is a day flying species which, unlike the European hornet [Vespa crabro], ceases activity at dusk

There are some excellent publications prepared by the Non-Native Species Secretariat [NNSS] and available on their website

What you can do about it…although it is not in Ryedale as yet…

Trapping is an option, and RBKA has prepared instructions for a sentinel trap based on a publication provided by the National Bee Unit. The RBKA Nelson Trap is a simplified, and we believe easier to construct, trap. It is uses cheap and readily available materials. This trap reduces damage to other species and is specific for the Asian Hornet. Instructions may be downloaded [RBKA Nelson Trap] or  viewed online.

If you suspect you have caught an Asian hornet then send details, with a photograph and location information, by email to:  alertnonnative@ceh.ac.uk or you may submit details online through this link – Hornet Sighting

Do NOT under ANY CIRCUMSTANCES disturb or provoke an active hornets’ nest [as if you need telling!!].

Interesting videos…
