This little moth I have found is called a Brimstone Moth, it's yellow like the Brimstone Butterfly but not as bright yellow. Strangely I only see these at work when I am on night shift, they are obviously attracted to the lights which are on all night in some rooms. This was on the office wall. I wonder what it lives on as it always seems to be in the building somewhere.
