Can anybody tell me if these are normal ladybird larva and pupae, or are they the dreaded Harlequin sort. They appeared on my wife's clematis a few days ago, and we don't know whether to kill them, or nurture them.
Let nature take its course would be my suggestion
Best advice from all quarters nowadays is that Harlequin ladybirds are here to stay ... they cannot be eradicated and should be left to get on with eating aphids. They're certainly doing a fantastic job in my garden.
