Had to try.

       Mary's Buddleja is seldom devoid of a handful of Butterflies and I can't resist having a go.
       Yesterday, if I remember right I thought I'd shot my last Butterfly (s)  for this year - FAT chance; who was I kidding?
       However, I finally changed Tack and had a go at a flight.  Imagine the speed of BRRRRRT of what mine chooses to call "High speed continuous".  What you see here is the flight distance between a couple of RR  in the BRRRRRT.
