Im 90% sure it was, and ive reported it to beekeepers and some govt body, but as I didnt get a photo they wont follow up. One said unlikely to be the giant asian hornet, more likely just the asian hornet, though this thing was a good 2 inches long. Fairly sure it wasnt a giant woodwasp, which are harmless, it didnt have the egg laying tube. I know for fact it was not our native hornet which I see every year. Trouble is, if one nest gets going, by the end of the season 250 new queens will leave to start new nests, and then thats it. They destroy bee colonys in a short space of time. If anyone sees any try and get photo and report to relevant people and they should follow up/try and track them to nest and destroy. Most likely in south of country where milder weather
