No they do not, and indeed I have some doubts that the ladybirds shown here are in fact naughty ones. The incomers are, in my understanding, much flatter and larger than these. These seem to have the typical domed back that designates a 'good' ladybird. The 2 spot ladybird is a 'goodie', as shown on Springwatch recently. However, I do not pretend to be an expert.
The babies of ladybirds do indeed look like ferocious monsters when you first meet them, but what a delight to see on the roses!
