Chimney Sweeper moth on Mount Caburn today on a "Pride of Sussex" flower? NO it is a Forester moth.

I thought that it looked like a Chimney sweeper moth, Odezia atrata but Colin Knight has kindly corrected the ID as a Forester moth.  See his wonderful pictures at https://www.colinknightimages.com/  Thanks Colin and best wishes with your pubic speaking!
  It looks similar to a Burnet moth but has no red spots at all.
