Butterworts were quite common where I used to live. I lived at the base of a mountain and literally a two minute drive up the hill landed me in grandiflora territory. I've still never seen a sundew though. I don't know the areas they tend to like. I know the pings prefer high regions, I've even seen them growing out of cliff faces on the Connor Pass on the way to the Dingle Peninsula. Kerry is good for Pings. Any advice on the sundew habitats would be good as I'd love to see some.
butterworts usually grow in base rich (calcareous) flushes and seepages, not necessarily in bogs,although you will find some on acid peat too, but often on cliffs (I suspect that exposed cliffs are oxidisng and raising nutrient levels, which the Pings like). look for slightly grey looking short vegetation patches on hillsides, which can indicate patches of glaucous sedges (carex) which like the same conditions. Not sure about P.lusitanica preferences though...
Drosera like acid conditions, in raised or blanket bogs, or acid flushes on moorland. D.rotundifolia is usually growing on Sphagnum, so look for this as an indicator, also on bare peat and sand beside paths, sometimes quite dry. D.intermedia and anglica like the really wet areas, usually on bare peat with a little standing water
