Sheer FLUKE.

Jerra & I were having a wander, point, shoot, session this p.m. 
While looking at the Romneya coulteri I spotted this obliging bee keeping about the same distance from the lens as the flower was. It was NOT obliging enough to wait for me to set up the camera to suit wing beats - hence the unique One Winged Bee.
That aside, I was fair to middlin' chuffed, overall. Definitely an unlikely repeat; unlike the rest of the collection.
