On the way back I saw a ladybird and wondered if it was one of the new invasive breed, the harlequin ladybird. I am no ladybird expert. I took a picture to research later but while the spots are nice and clear it was not much help. It was disappointing to discover that identification as less easy as some of the ladybirds are very variable in colour, size and spot number, and the harlequin is one that is hugely variable. It might be, as a white triangle at the front was mentioned as a common feature, not the shape I had been looking for.
