Saw a black ladybird in the allotment this morning. I think it could be a Pine Ladybird except that it's pretending to be a blackcurrant!
"He had softly and suddenly vanished away---For the Snark was a Boojum, you see." The Hunting of the Snark, Lewis Carroll
It's an alien, harlequin ladybird doing a good impression of a pine ladybird.
