These ladybirds are the invasive harlequin ladybird (succinea form)- thanks to the excellent wild about britain forum with help with the identification.
These ladybirds are believed to be a threat to the UK native species and a survey of how they are spreading can be found at: http://www.harlequin-survey.org/default.htm - Where this small population has been recorded.
