Hertfordshire Notes: Though quite widespread across the county the Frosted Orange is somewhat locally distributed and never arrives at the light trap in any great number. The need for thistles, burdocks or similar plants that will survive the summer without being cut or pulled must be a limiting factor.

Middlesex Notes: Widespread and common but completely avoiding the south-east area of dense urbanisation.
