Asian hornet

The striped menace

Asian hornet sightings are at highest levels yet – know what they look like and report them to save our native species.

The invasive Asian hornet is a serious threat to the UK’s wildlife, especially our native honeybees and other insects. They impact the pollination of plants and crops, which in turn affects us all, and they are a substantial risk to the beekeeping community. There are also concerns about risks to people and animals should the insects attack them. 

Unfortunately, since 2016 they have been spotted on the Channel Islands and all across southern England with Defra regular reporting showing numbers of sightings fluctuating between years. However, this year has so far seen a substantial increase in reports, 28 to date, mainly in Kent and Devon according to the National Bee Unit website which provides the most up-to-date records.  

If that’s where you are based or travel to regularly, you need to be vigilant. However, as Asian hornets have popped up all over the UK, it’s important that all of us know how to ID them correctly and know the differences between the Asian and our native hornets. You also need to know how to report a sighting. 

Shooters are ideally placed to monitor this species as we often have access to privately owned land, far away from public rights of way. Our sightings could be critical in the early detection of new arrivals or spotting out-of-the-way colonies.

Reporting a sighting is easy

  1. The preferred way is to use the Asian Hornet Watch App which you can download for Android or Apple devices.
  2. Alternatively, you can use a form on the UK Centre for Ecology and Hydrology website, or send a photograph and location details to  alertnonnative@ceh.ac.uk  

How can you be sure you’ve seen an Asian hornet?

The GB Non-native Species Secretariat has some excellent resources on its alert pages, which include a clear two-page identification sheet in English and Welsh. I thoroughly recommend looking at these because they also cover similar-looking species like the native European hornet, giant woodwasp and the median wasp.

You are most likely to confuse the Asian hornet with its European counterpart but there is an obvious difference in the pattern of black and yellow on the abdomen. Asian hornet’s abdomen segments are almost entirely black apart from the fourth segment which is yellow. European hornet’s abdomen is mostly yellow, with only the first and second segments being black.

The nests themselves are often rugby-ball sized but can get substantially bigger and are often high up in the canopy of trees. However, there are exceptions to the rules, with a nest being found in a derelict building on Jersey in August this year, and nests found in Guernsey were tucked into hedges and brambles.

Make sure you know the difference between the Asian hornet and our native species. If you spot the dangerous invader, or if you see evidence of its presence, please report it without delay!
