Cold Edge and Ovenden Moor

I did the Wider Countryside Butterfly Survey late morning around the usual Tetrad. It was reasonably warm but not really enough sunshine. I ended up with more day-flying moths than butterflies but both were good even if the butt's were in short supply.

Same species Pug x 2 near The Withens former pub - photo's below for scrutiny. 

Very small pugs (second individual not very good photo) - both were flying when the sun shone, both feeding on small white flowers ! Nearest I can get is Marsh Pug.......any thoughts ?
