Using My 50mm Lens: A Picture for Photo Challenge #3

When I came home from work I noticed a Swallow Tail butterfly was flittering around in our front garden.  I grabbed my camera and whatever lens was attached and ran out the door.  This was one of a dozen pictures I snapped.

Check out the lovely bokeh this lens produces:
