Could be.................the Orange Ladybird, Halyzia 16-guttata, which is fairly widely distributed in the south of Britain. It breeds on Sycamore, Dogwood and a range of other deciduous trees and, interestingly in view of your sighting, hibernates in, among other things, the foliage of Scots Pine.
The colouring and markings of some of the ladybirds is quite variable among individuals of the same species and according to age; some that are supposed to have spots don't, and the pattern variations can be confusing. The Orange Ladybird has white spots and apparently is generally less prone to colour variants than most, but I'm not any sort of an expert to be able to say whether a ladybird was actually a 'wrong-coloured' 10-spot, rather than an orange. It could be this summer's special subject!
