Ladybirds a plenty

I went along to tennis and whilst I was waiting for a court had a walk around the park not expecting to find much but there were lots of htese Harlequin ladybirds in the hedges on the Ivy and the Rosehips. I was spoilt for choice so many different patterns and colouors too. I believe they are not native but don't seem to be upsetting the native varieties too much.
