Ladybird, Ladybird, fly away home!

I have been watching with fascination the life cycle of the ladybirds on the swan plant.  I have asked my hubby not to spray the aphid on this plant so that the ladybirds have a ready supply.  It has paid off as I can't count the number of adult ladybirds.  There are the larvae there and its an amazing journey watching them grow and change into the adult ladybird.
