Although the others you describe are probably the harlequin ladybird, Harmonia axyridis, your metallic stripy 'ladybird' is almost certainly a rosemary leaf beetle, Chrysolina americana. Look out for the pale grey grubs, up to 10 mm long, sitting hard up to the stems, nibbling the edges of the leaves. The beetle rarely does much damage and it is such a wonderful looking insect.
