Eighty nine Harlequin Ladybirds eliminated from one small cherry tree.

This cherry tree gets infected with aphids every year.  And in recent years has attracted Harlequin Ladybirds.
This is a Harlequin larva ready to start pupating.
 These are more advanced pupae.
An adult Harlequin beetle -- crushed for this picture.  Harlequins allegedly escaped from a greenhouse in Belgium after bringing them from Asia.  They outperform native British Ladybirds, which are threatened as a consequence.
Eighty nine Harlequin larvae, pupae and one adult beetle were collected in a small vessel from this one small tree...
 ... and then dispatched to give our native Ladybirds a better chance to compete.
This tiny native Ladybird, Propylea 14-punctata appeared yesterday in my house. 
I've done my bit to help it survive.
