I spent a very relaxing afternoon yesterday cruising between Odiham and The barley Mow near Crookham on the John Pinkerton !!. The weather was ideal, sunny but not too hot. Sandwhiches, cake and a hot drink were provided by the organisers.. It was the first time I have been on the new John Pinkerton, the original having been replaced about 6 years ago.
I saw lots of ducks and dragonflies but was particularly impressed by a butterfly (I assume not a moth) that was present in abundance. Non of us on the boat could identify it and I couldn't find it in my butterfly book. It was quite large and from some angles appeared black, but when its wings tipped towards the sun it showed itself to be a rich, dark blue. There didn't appear to be any white or other markings on its wings.
Can anybody suggest what it might have been?
