Following the increase in Asian Hornets in the Channel Islands this summer, they have now been found in Cornwall and in September the first nest was located in Hampshire, at New Alresford. We all should remain vigilant and contact the local Bee Inspector or use our contact page to alert a member of the Association.
The nest is the size of a football and the colour is dependant upon the type of wood used for the nest.
Asian hornet in the UK: Update and Request for Heightened Vigilance.
An Asian hornet has been found in Lancashire and surveillance activity is underway.
Around April, surviving V. velutina queens begin a small primary nest, often in a sheltered location such as in the eaves of a roof or in a garden shed. Here they raise the first clutch of workers who take over the queen’s foraging duties. At this stage the nest grows quickly, and the hornets often move to establish a secondary nest where there is more space to expand.
These nests can become very large, and are often located high up in the tree canopy, close to a food source such as apiaries.
From late September to October, the mature nest produces males and then virgin queens which mate and disperse. However, the beginning of this stage of nest reproduction can vary, depending on climatic conditions. A single mature nest produces on average 11 foundress queens after taking into account overwintering mortality of the potentially hundreds of queens that first disperse in autumn.
A consortium of scientists from the NBU and the Universities of Warwick and Newcastle have used data on the spread of the Asian hornet in France to develop a mathematical model that can estimate the hornet spread in the UK. The highly mobile nature of the hornet means that the range of possible additional nest locations in 2016, estimated using the model, covers a wide area.
Asian hornets can be trapped by using either commercial traps to prevent populations expanding. Asian Hornet Identification sheet.
Should you find a suspect Asian hornet or nest, please contact the Non Native Species Secretariat immediately using their alert email address: email@example.com giving as much information as possible. Please include details such as your name, the location where the hornet was found and if possible an image of the specimen. Even if you are unsure of whether it is an Asian hornet, send it in any way – it’s better to be safe than sorry.
