There were so many ladybirds at the visitor's centre and I was intrigued to see a black one with one red spot as I have never seen one like that before.
I have just noticed that this collage says May 2016 and I have no idea why as the photos were all taken today. It was made in Picasa so perhaps that's when I uploaded Picasa to my laptop?
Lovely collage Rosie, Mark @markp is absolutely correct the black one is an alien Harlequin one that carries a disease that killing off our native ones:)
I found one like that last year and discovered the same as Peter and Mark have commented above. A real shame. Surprised that there are so many still around. They make a lovely collage.
