I've photographed small moths on flowering composites recently, and think they may be the same species. The first was on 23rd Sep on common thistle, the second on hawkweed oxtongue on the 25th. Both were on farmland paths nr Beverley, East Riding.
It is a nettle-tap moth, Anthophila fabriciana
I notice some of yours are on a hawkweed. Yellow composites seem to be popular with this species, as shown by this recent ID posting - http://www.nhm.ac.uk/natureplus/message/34352#34352
Thanks Mike. I think I've got my eye in for it now. It was the only insect on yellow composite flowers [Picris, Leontodon & Taraxacum] I saw on a walk yesterday, apart from a few small flies.
