Some years there are lots of ladybirds and others there are very few. I believe the Summer of 2010 was very rich in ladybirds, particularly this sort – which I had never seen before.
A little research online, tells me that it is a Harlequin Ladybird (Harmonia Axyridis), which is apparently an invasive species.
At the time, I thought it looked rather neat and beautiful, perched on a wrought iron railing in one of the squares in Bath.
Close-up photography is much harder than most people credit, so I am rather pleased this worked out.
