The BBKA has a map of Asian Hornet sightings here

My fear is that it will get more populated as time goes on. The fact that sightings are spread around the country means that Northerners (and Easterners in my case) need to worry as much as those living on the S coast and cannot assume that the hornet will just spread from Cornwall upwards.

It's inevitable that there will be continued accidental imports and some nests are going to get missed. They may already have been missed.
We need a hard Brexit and close our borders to Europe ;)

There's a paper:

Predicting the spread of the Asian hornet (Vespa velutina) following its incursion into Great Britain

The BBKA map is tabbed for years -so you can see this years, last and the year before. It'd be nice to think no more locations will be added, but ...

Interesting article : The invasion, provenance and diversity of Vespa velutina Lepeletier (Hymenoptera: Vespidae) in Great Britain

one of the references
Production of Early Diploid Males by European Colonies of
the Invasive Hornet Vespa velutina nigrithorax ... ne.0136680

Low genetic diversity means they produce more diploid males at the start of the colony rather then females - and that weakens the colony.
