I heard Vaughan's call of "awesome" when I was getting lunch items from the caravan. This fabulous cricket-like fellow had run up onto Vaughan's chair, surprising all of us!
He/she was very speedy and it was hard to capture good shots. After racing around the table a few times, our lunchtime guest found shelter under one of our plates - and seemed happy to stay there until being returned to ground level. (I haven't yet sought to identify the interloper but if I work out his/her proper name, I'll include it here).
