What's Buggin' You?

I'm not sure this is the best picture of the day, but it's my favourite. I happened to notice this bug, clinging to the window of the viewing gallery during our family visit to Pensthorpe. The day was bright and sunny, but the wind was cold. I snapped happily at many a water fowl, but this shot was suitably different and for that I like it. I hope you like it too.
