I agree with Peter that there seem to be strange happenings this year. I have had two Frosted Greens in the last week, not a common moth in my garden usually. Last night Marbled Brown, Brimstone and Mullein among the more usual fare. I am also getting several out of the ordinary Clouded Drab, many of them very pale. I wonder if their colouration is a temperature dependent thing like pink Vestals. Well done with the Silver Cloud Dave. This is not a common moth in Somerset but seems to like that north coast area.
