The map is the latest I can find of the progression of vespa velutina nigrithorax (asian hornet) in its colonisation of France. It has been progressing at about 100 km. per season. The 3 isolated areas indicate where an egg laying female has obviously found some other form of transport than flying. Its installation and progression are now considered irreversible, and it will only be a matter of time before the rest of Europe is *invaded*. In France it is considered a very serious problem.
Their nest can be up to a metre high, with a diameter of 80 cm. The carapace is about 8 cm. thick. The nest can contain up to 20.000 cells.
Perhaps you still have time in Scotland to start rebuilding Hadrian's wall.
