Unknown caterpillar

The weather was warm and sunny this morning so I went for a walk after school.  The first thing I saw was two jet black horses for a funeral, years ago the lady used to do my job and she was a real character, now in her final resting place.  I walked and then sat for a while, met some people on the walk that I haven't seen in a long while, so chatting, walking and photography filled the morning!  For the first time there were quite a few butterflies around and a tiny moth (I think) if anyone knows what it is I'd be pleased to know, first extra.
