I stumbled upon this sleeping butterfly while cleaning out an old pigsty. It looks quite the worse for wear – covered in dust and slightly caught up in old spider webs – but hopefully, having made it this far through the winter months, it will survive and soon fly away.
Several species of UK butterflies try to survive the winter in their adult form. Of those, the most common are the comma, the peacock, the small tortoiseshell and the brimstone.
