I think that these are both forms of the same species Apologies for the poor photos, especially the second one.
No interactions present.
I've recently taken part in the Bugs Count run by OPAL. The 2-spot ladybird is one of six bugs they are keen to record sightings of. You can upload your photos to www.OPALexplorenature.org/bugscount or email them to bugscount@OPALexplorenature.org, giving date and location details.
I've sent them to the UK Ladybird Survey site as usual.
