Some behaviour I haven't seen before. This Orange tip seems to have been taken by what I presume is a Sawfly. The fly with single the lifeless butterfly occasionally made flights up over the bush it was in, the 'flat', floating butterfly attracting my attention. My book (Collins Complete Guide to British Insects) says sawflies are partly carnivorous so perhaps proof of the pudding.
