A few years ago we went to Greece for a holiday and there, one sunny afternoon we saw hornets buzzing past our wide patio. These were far bigger than your average wasp. The largest we saw was close to 2 inches/5cm!
I had a plate of steak and chips and a few salad leaves, and one of those hornets landed quite gracefully onto my piece of meat. While we kept very still, I watched as it literally gnawed a piece of meat beofre tucking it beneath its legs and flying off. The hornet returned to take another little piece, about 4mm I reckon and its thirdf return, the hornet cleverly cut a circle of spinach leaf, curled it up like carpet beneath its legs and took off!
It was a WOW moment! Just beyond our patio wall was the hornets' flight path. Thankfully not inside it. It was a fascinating watch, but we never discoved their nest. Probably up in the hills of Koss, we thought.
