Am I right in thinking that this is Catoptria margaritella? Possibly a wanderer as the micro book describes its habitat as boggy heaths, mosses and moors, which doesn't sound like Rhoose Point to me...!
Puzzled by this one - I'm assuming it's a melanic form of a geometrid, unless I've missed something!
I first thought this might be Acrobasis advenella, which I have recorded here before. The inner pale cross-line doesn't look quite right to me though. Possibly A marmorea? It's also lacking the paired black dots at two thirds.
