Hi, Robert. Your Lygaeus saxatilis seems to be Corizus hyoscyami L. of the family Rhopalidae. Lygaeus has black lateral edge of its shards, but the bug on the photo has red one.
It is very likely that Lygus rugulipennis is Lygus pratensis in fact. L.rugulipennis has often W-shaped dark spot on its scutellum or at least bifurcated spot, but never has solid triangular spot unlike L.pratensis. Moreover, L.pratensis has reddish color pattern of its shards.
