Reply to captrjslog. Yes, hornets are getting more common and more widespread. They are mainly woodland creatures and the centres of their UK distribution used to be the New Forest, the West Country and the Shires between Bath and London. There used to be many gaps in the recording maps around south-east England, London, East Anglia and the Midlands. However, in the last 20 years hornets have spread to areas in which they used never to occur. I was really thrilled to see one in Dulwich a year or so ago and found the disused nest in a tree hollow. Despite their ill-deserved reputation, hornets are more docile and more secretive than the other social wasps. They are magnificent creatures and are a wonder to watch. Harry is lucky, I had to wait until I was 45 before I saw one.
