Along with most of the UK we have been having a rather mild couple of weeks. So mild in fact that I've already seen a butterfly!
I'm not sure where it had been over wintering but on the 24th of February my attention was distracted by a Speckled Wood sunning itself on the inside of my study window. It was a warm enough day to have the window open but I wouldn't have thought it was late enough in the year for butterflies. Unfortunately I have a number of plants on my windowsill which got in the way of a decent photo (every time I tried to move one of them it upset the butterfly so it didn't seem worth trying too hard). After about twenty minutes it eventually flew out of the open window.
I've no idea if it will have survived the cooler temperatures overnight, but there is definitely something weird going on with the seasons this year. There was blossom on a cherry tree nearby just after Christmas and now a butterfly in February!
